SMA01M-15 — Isolated unregulated single-output DC-DC converter
MEAN WELL SMA01M-15 is an isolated, unregulated single-output DC-DC converter with a 12 V DC nominal input, a 10.8–13.2 V DC input range and 15 V DC output. The catalog rates this model at 1 W with a 0–67 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.

100 kHz typical. |
Input and protection
| Input voltage |
10.8–13.2 V DC; normal input 12 V DC. |
| Typical efficiency |
79% at the stated reference test conditions. |
| Input current |
110 mA at full load; 15 mA at no load. |
| Input filter |
Built-in EMI filter; capacitor-type input filter. |
| Input fuse |
The catalog recommends a 250 mA input fuse for this 12 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. |

Mechanical design and selection
| Dimensions |
12.7 × 10.16 × 7.1 mm (L × W × H). This is the model-specific height for the 12 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. |
