Product details
Overview
DRDPB16W-7 from Diodes Incorporated is a dual-function SOT-363 packaged device integrating a pre-biased NPN transistor and a fast switching diode for relay driver applications. Confirmed parameters include 50 V supply voltage, 600 mA output current, 75 V peak reverse voltage, 0.3 V output saturation voltage, and 4.0 ns reverse recovery time. It operates across –55°C to +150°C and is used in automotive body control modules for driving electromagnetic relays.
For engineers reviewing the DRDPB16W-7 datasheet, DRDPB16W-7 pinout, DRDPB16W-7 application, or DRDPB16W-7 equivalent, key selection criteria include integrated bias resistor network (1 kΩ/10 kΩ), low VCE(SAT), fast diode recovery, thermal performance under pulsed relay loads, and AEC-Q101 qualification status for automotive use.
Technical Context
The DRDPB16W-7 combines a pre-biased NPN transistor with built-in base resistors (R1 = 1 kΩ, R2 = 10 kΩ) and a 75 V, 500 mA switching diode in a single SOT-363 package. Its transistor delivers 600 mA output current with 0.3 V saturation voltage at IO/IL = 50 mA/2.5 mA, while the diode exhibits 4.0 ns reverse recovery time and 4.0 pF capacitance at 0 V.
This configuration eliminates external bias components and provides integrated flyback protection for inductive relay coils. The device supports direct microcontroller GPIO interfacing with logic-level input compatibility (VIN = –5 V to +10 V) and operates reliably up to +150°C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar relay driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD120DP5T1G | Single NPN pre-biased transistor (no integrated diode); 100 V VCEO, 100 mA IC. | Requires external flyback diode and base resistor; limited to low-power signal relays. | Select when only transistor function is needed and board space allows discrete diode placement. |
| DMN3028LSD-13 | 30 V, 6.5 A logic-level N-channel MOSFET in SOT-23; no integrated diode or biasing. | Higher current capability but requires gate driver IC or resistor network; no flyback protection. | Choose for high-efficiency, high-current DC loads where active clamp or TVS is already implemented. |
Compared with NSVD120DP5T1G and DMN3028LSD-13, DRDPB16W-7 uniquely integrates both biasing and flyback functions in one AEC-Q101-qualified SOT-363 device-reducing component count, layout complexity, and failure modes in automotive relay interfaces.

FAQ
Is DRDPB16W-7 pin-compatible with DRDP006W-7?
No. DRDPB16W-7 contains a pre-biased NPN transistor and switching diode, while DRDP006W-7 integrates a PNP transistor and diode. Their internal configurations differ: DRDPB16W-7 has base resistors (1 kΩ/10 kΩ) and emitter-grounded topology; DRDP006W-7 is PNP-based with collector-grounded operation. Pin assignments and electrical behavior are not interchangeable.
Does DRDPB16W-7 require external base resistors?
No. DRDPB16W-7 includes integrated 1 kΩ series and 10 kΩ pull-down base resistors. This allows direct connection to 3.3 V or 5 V logic outputs without external components. The internal resistor network ensures proper biasing, noise immunity, and guaranteed turn-off-verified across –55°C to +150°C operating range.
Can DRDPB16W-7 drive a 24 V relay with 100 mA coil current?
Yes. With 600 mA rated output current and 0.3 V VCE(SAT), DRDPB16W-7 fully supports 24 V relays drawing up to 100 mA coil current. Power dissipation remains below 30 mW (100 mA × 0.3 V), well within its 200 mW total device rating. Thermal performance is validated per Figure 1 derating curve on FR-4 PCB.
What is the maximum inductive load energy DRDPB16W-7 can safely clamp?
Based on its 75 V VRWM and 500 mA IF, DRDPB16W-7 safely clamps flyback energy from relays with L × I²/2 ≤ 0.5 × (24 V)² / 75 V ≈ 7.7 mJ. This covers typical 12 V/24 V automotive relays (e.g., 12 V, 80 Ω coil = 150 mA, ~0.9 mJ). For higher-energy loads, external TVS or RC snubbers are recommended.
