Internal power dissipation 500 mW, as specified in the catalog.
Remote ON/OFF Pin 1 (R.C.), referenced to −Vin: ON above 3.5 V DC within the specified range up to 160 V DC, or open; OFF below 1.2 V DC or shorted to −Vin.

Mechanical and environmental specifications

Parameter Specification
Dimensions 31.8 × 20.3 × 12.7 mm (L × W × H).
Case and cooling Non-conductive black plastic; fully encapsulated. Free-air convection cooling.
Pin assignment Bottom-view numbering: pins 2 and 3 = −Vin; pins 22 and 23 = +Vin; pins 9 and 16 = COM; pin 11 = −Vout; pin 14 = +Vout. Pin 1 = R.C. (remote ON/OFF). N.C. means no connection. Follow the drawing orientation when laying out the PCB.
Mechanical installation DIP24 footprint; 2.54 mm grid, 15.24 mm between pin rows and 3.8 mm lead projection. Pin size: 0.5 ±0.05 mm. Use the model-specific bottom-view and top-view PCB drawings.
Working environment −40 to +85°C with load derating; 20–90% RH, non-condensing.
Load derating Natural convection: 100% load through +65°C, then derate to 50% at +85°C.

Temperature coefficient 0.03%/°C (0–71°C).
Case temperature +100°C maximum.
Soldering At 1.5 mm from the case: 260°C maximum for 1–3 s.
Vibration 10–500 Hz, 2 G, 10 minutes per cycle; 60 minutes along each X, Y and Z axis. Mounting complies with EN 61373 Category 1, Class B.
Catalog packing reference per unit 16 g, from the catalog PACKING entry; not a measured net weight.
Manufacturer packing 10 pieces per tube; this is the catalog packing arrangement.

Isolation, EMC and manufacturer information

Parameter Specification
Isolation withstand Input-to-output: 3 kV DC.
Isolation resistance Input-to-output: 100 MΩ at 500 V DC, 25°C and 70% RH.
Isolation capacitance 1000 pF typical.
EMC emissions BS EN/EN 55032 conducted Class A with external components. Radiated: not specified (N/A).
EMC immunity BS EN/EN 61000-4-2: Level 2, ±8 kV air / ±4 kV contact; -4-3: Level 2, 3 V/m; -4-4: Level 1, 0.5 kV; -4-5: Level 1, 0.5 kV line-to-line; -4-6: Level 2, 3 V (e.m.f.).
Approval EAC TP TC 004 approved.
System EMC Reconfirm EMC compliance in the final equipment. The component specification does not replace the complete system assessment.
EMC application circuit Conducted Class A requires an external filter. Obtain a manufacturer-confirmed filter design and component voltage ratings suitable for the full 43–160 V DC input range before implementation; verify EMC in the complete equipment.
Railway standards EN 50155, including EN 61373 for shock and vibration and EN 50121-3-2 for EMC.
MTBF 1200 k hours per MIL-HDBK-217F at 25°C; not a service-life or warranty guarantee.
Manufacturer warranty reference The catalog states a 3-year manufacturer warranty; the manufacturer’s applicable terms govern.
