Description

DETN01M-12SC — 1W isolated DC/DC converter

MEAN WELL DETN01M-12SC is a 1 W isolated, unregulated DC/DC converter in an SMD package. It accepts 10.8–13.2 VDC input (12 V nominal) and provides ±12 VDC dual output at 4.2–42 mA per rail. This SC-suffix version offers continuous short-circuit protection; observe its thermal derating and case-temperature limits.

Output and model selection

Complete model / series DETN01M-12SC / DETN01. Input code M: 12 V nominal; output code 12: ±12 V dual output. SC selects the optional continuous-short-protection version.
Conversion and rated power Isolated, unregulated dual output; 1 W total rated power. The positive and negative rails share this total; rounded current values do not increase the rated power.
Output voltage and current ±12 VDC relative to Common; 4.2–42 mA per rail. Observe the stated minimum load on each rail.
Efficiency 82% typical for this model; the series feature statement is up to 83%.
Maximum capacitive load 220 µF, as listed in the model-selection table.
Voltage accuracy ±2.0%.
Line regulation 1.2% for 1% input variation; measured from low line to high line at rated load.
Load regulation ±8%; measured from 10% to 100% rated load.
Ripple and noise 75 mVp-p. Measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Switching frequency 100 kHz typical.
Specification conditions Normal input voltage, rated load, 25°C and 70% RH, unless otherwise specified.

Input, isolation and protection

Input voltage 12 VDC nominal; operating range 10.8–13.2 VDC.
Input current No load: 12 mA; full load: 103 mA.
Input surge 16 VDC for 100 ms maximum; this does not extend the continuous input range.
Input filter Internal capacitor.
Recommended input fuse 300 mA slow-blow fuse.
Internal power dissipation 500 mW.
Input/output withstand voltage 3 kVDC input to output.
Isolation resistance 100 MΩ between input and output, tested at 500 VDC, 25°C and 70% RH.
Isolation capacitance 80 pF typical.
Short circuit Continuous short-circuit protection for the optional SC-suffix version.

Environment, reliability and compliance

Operating temperature and derating −40 to +105°C ambient, subject to the derating curve. SC curve: 100% load through +100°C; derate above +100°C toward zero at +105°C. The 40% point is close to, but below, +105°C; it is not a 40% rating at +105°C.
Maximum case temperature +100°C maximum. The ambient range and derating curve do not override this case-temperature limit.
Cooling Free-air convection.
Working humidity 20–90% RH, non-condensing.
Storage temperature and humidity −55 to +125°C; 10–95% RH, non-condensing.
Temperature coefficient 0.03%/°C over 0–85°C.
Soldering Hot-air reflow only: peak 240°C for 10 seconds maximum; above 220°C for 60 seconds maximum. The separate soldering specification is 240°C maximum for 1–10 seconds, measured 1.5 mm from the case.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes.
Safety standards UL62368-1 and EAC TP TC 020/2011 approved, as listed in the specification.
EMC emission BS EN/EN55032 (CISPR32): radiated Class B without additional components; the conducted-emission entry is N/A.
ESD immunity BS EN/EN61000-4-2: Level 3, ±8 kV air.
Other immunity BS EN/EN61000-4-3: Level 2, 3 V/m; -4: Level 1, 0.5 kV; -5: Level 2, 0.5 kV line-to-line; -6: Level 2, 3 V; -8: Level 1, 1 A/m.
External input capacitor for EFT and surge An external input filter capacitor is required to meet BS EN/EN61000-4-4 and BS EN/EN61000-4-5. The datasheet recommends 470 µF / 100 V.
MTBF 880,000 hours minimum, MIL-HDBK-217F at 25°C; a reliability estimate, not a warranty duration.
Warranty 3 years, as stated in the datasheet.
