MEAN WELL SMA01 series: Isolated unregulated single-output DC-DC converter - SMA01N-05

Description

SMA01N-05 — Isolated unregulated single-output DC-DC converter

MEAN WELL SMA01N-05 is an isolated, unregulated single-output DC-DC converter with a 24 V DC nominal input, a 21.6–26.4 V DC input range and 5 V DC output. The catalog rates this model at 1 W with a 0–200 mA output-current range. It uses a non-conductive plastic dual-in-line package, internal SMD construction and natural convection cooling. Account for input and load variation when using this unregulated output.

Model and output specifications

Complete model / series SMA01N-05 / SMA01.
Model selection Input code N selects 24 V DC nominal input; output code 05 selects 5 V DC.
Output voltage 5 V DC, single output.
Output current range 0–200 mA.
Rated output power 1 W.
Voltage accuracy ±2.0%.
Line regulation ±1.2% for each 1% input-voltage variation; measured from low to high input at rated load.
Load regulation ±8.0%, measured from 20% to 100% rated load.
Ripple and noise 100 mVp-p maximum. Measured at 20 MHz bandwidth with a 12-inch twisted pair terminated by 0.1 µF and 47 µF capacitors.
Switching frequency 100 kHz typical.

Input and protection

Input voltage 21.6–26.4 V DC; normal input 24 V DC.
Typical efficiency 77% at the stated reference test conditions.
Input current 57 mA at full load; 11 mA at no load.
Input filter Built-in EMI filter; capacitor-type input filter.
Input fuse The catalog recommends a 150 mA input fuse for this 24 V input type.
Overload protection Momentary. The datasheet lists the protection type as “Broken”; it does not specify continuous-fault operation or automatic recovery.
Short-circuit protection Momentary. The datasheet lists the protection type as “Broken”; use the recommended input fuse and do not rely on automatic fault recovery.

Operating conditions and isolation

Operating temperature and cooling −40 to +90°C, with free-air convection. Full load is specified through +85°C; apply derating above +85°C.
Load derating The curve permits 100% load through +85°C and 50% at +90°C. The operating rating ends at +90°C.
Working humidity 20–90% RH, non-condensing.
Storage conditions −55 to +125°C; 10–95% RH.
Temperature coefficient ±0.05%/°C over 0–50°C.
Vibration 10–500 Hz, 2G; 10 minutes per cycle, for 60 minutes along each of the X, Y and Z axes.
Reference test conditions Normal input of 24 V DC, rated load, 25°C and 70% RH, unless otherwise specified.
Input-to-output withstand voltage 1.5 kV DC.
Isolation resistance 100 MΩ between input and output, tested at 500 V DC, 25°C and 70% RH.
Isolation capacitance 80 pF maximum.

Mechanical design and selection

Dimensions 12.7 × 10.16 × 7.62 mm (L × W × H). This is the model-specific height for the 24 V input type.
Pin assignment Bottom view: pin 1: −Vin; pin 4: +Vin; pin 5: +Vout; pin 7: −Vout.
Mechanical drawing details Dual-in-line package with the catalog industry-standard pinout. Pin section 0.50 × 0.25 mm; lead projection 3.81 mm. Use the complete bottom-view footprint and the model-specific body height above.
Unit weight reference 1.6 g, explicitly stated as a catalog packing reference per unit.
Manufacturer packaging reference 40 pieces per tube; tube gross weight 90 g. Up to 6000 pieces in 150 tubes per carton; carton gross weight 14.3 kg. These packaging weights are separate from the per-unit reference.
Optional isolation version The series lists a 3000 V DC input-to-output isolation option. This separate factory option does not change the standard 1500 V DC rating of the model shown here; confirm the required configuration before ordering.

EMC and manufacturer references

Safety standards EAC TP TC 020/2011 approved.
Catalog markings FCC, EAC, CE and UKCA are shown in the catalog.
EMC emission BS EN/EN55032 Class B, FCC Part 15 Class B and EAC TP TC 020.
EMC immunity BS EN/EN61000-4-2, -3, -4, -5, -6 and -8; light-industry level, criterion A; EAC TP TC 020.
Design features Internal SMD technology and a non-conductive plastic case. The manufacturer describes a low-cost, high-reliability design.
Manufacturing test 100% burn-in test.
MTBF reference 700 khrs minimum, MIL-HDBK-217F at 25°C; a reliability reference, not a service-life guarantee.
Manufacturer warranty reference The catalog states a 2-year manufacturer warranty.
