Product details
Overview
DRDP006W-7 from Diodes Incorporated is a dual-function SOT-363 packaged device integrating a PNP bipolar transistor and a switching diode for relay driver applications. It delivers -60 V VCEO, -600 mA IC, 100–300 hFE, 4.0 ns trr, and 75 V VRWM, enabling compact, high-reliability current-source relay control in automotive body electronics and industrial PLC I/O modules.
For engineers reviewing the DRDP006W-7 datasheet, DRDP006W-7 pinout, DRDP006W-7 application, or DRDP006W-7 equivalent, this page provides verified electrical parameters, validated SOT-363 terminal mapping, relay-driving use-case context, and two functionally comparable alternatives with documented differences in bias configuration and polarity.
Technical Context
The DRDP006W-7 implements a discrete PNP transistor (VCEO = -60 V, hFE = 100–300 at -150 mA) paired monolithically with a fast-switching diode (trr = 4.0 ns, VRWM = 75 V) in a single SOT-363 package. Both elements share thermal coupling but operate independently under separate bias networks.
No internal resistors are integrated - external R1/R2 biasing is required for transistor operation, distinguishing it from pre-biased alternatives like DRDNB16W. The diode supports flyback energy clamping during relay coil de-energization, with 500 mA IF rating and 8 pF Cobo at -10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60 V - Enables safe switching of 24 V/48 V relay coils with margin against inductive kickback. |
| IC (max) | -600 mA - Supports driving medium-power relays (e.g., 1 A coil rating with derating). |
| hFE | 100–300 - Ensures reliable saturation with modest base drive (e.g., -15 mA for -150 mA collector load). |
| trr | 4.0 ns - Minimizes switching loss and EMI during diode freewheeling in high-frequency relay cycling. |
| VRWM | 75 V - Clamps coil flyback voltage below destructive levels for typical 24 V systems. |
| PD | 200 mW - Total device power limit at TA = 25°C; requires thermal pad design for >100 mA continuous use. |
| RθJA | 625 °C/W - Confirms need for copper pour and layout-aware thermal management on FR-4 PCBs. |
Pinout & Package
SOT-363 (SC-70-6) surface-mount package with 6 terminals, molded green plastic housing, UL 94V-0 rating, and matte tin-plated Alloy 42 leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | PNP Emitter | Common emitter node for current-source output; connects to positive rail in relay driver topology. |
| 2 | PNP Base | Control input for transistor turn-on; requires external current-limiting resistor. |
| 3 | Diode Anode | Anode of integrated switching diode; ties to relay coil cathode for flyback protection. |
| 4 | Diode Cathode / PNP Collector | Shared terminal: diode cathode and PNP collector - connects to relay coil anode and load return path. |
| 5 | NC | No internal connection; electrically isolated; may be left floating or grounded per layout needs. |
| 6 | PNP Collector / Diode Cathode | Redundant connection to Pin 4 - confirmed identical node per DS30573 Fig. 6 and top-view diagram. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic PNP + diode integration | Reduces board area by eliminating discrete diode placement and routing; improves layout repeatability for relay drivers. |
| Epitaxial planar die construction | Ensures stable hFE and low leakage (<10 nA ICBO) across -55°C to +150°C operating range. |
| Lead-free, halogen-free "Green" packaging | Meets RoHS 3 (2015/863/EU), AEC-Q200 readiness, and IATF 16949 manufacturing compliance. |
| Fast reverse recovery (4.0 ns) | Suppresses voltage overshoot during coil de-energization, reducing stress on MCU GPIO or driver ICs. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Output Module |
|---|---|
Use Scenario: Driving 12 V/24 V electromagnetic relays for headlight, wiper, or door lock actuation. IC Role / Device Role / Timing Role: PNP transistor acts as high-side current source; integrated diode clamps inductive flyback. Use Value: Eliminates need for external flyback diode, reducing BOM count and PCB footprint by ~3 mm² per channel. |
Use Scenario: Controlling 24 V DC solenoid valves and contactors in factory automation I/O racks. IC Role / Device Role / Timing Role: Provides isolated, thermally coupled switching and protection in multi-channel output stages. Use Value: Enables 100 kHz+ relay cycling without thermal runaway due to shared RθJA and matched junction temperatures. |
| Smart Home HVAC Control Board | Medical Equipment Power Sequencing |
Use Scenario: Switching fan motors and compressor relays in residential HVAC controllers. IC Role / Device Role / Timing Role: Functions as fail-safe current-source driver with built-in overvoltage clamp. Use Value: Meets IEC 61000-4-4 EFT immunity requirements via fast trr and low CT (4.0 pF). |
Use Scenario: Enabling controlled power-up sequencing of isolated subsystems in diagnostic imaging devices. IC Role / Device Role / Timing Role: Delivers precise timing-margin control via predictable VCE(SAT) (-0.4 V typ.) and minimal propagation delay. Use Value: Guarantees <1 µs turn-off delay variation across temperature, supporting deterministic safety interlocks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar relay driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRDNB16W-7 | Pre-biased NPN with integrated 1 kΩ/10 kΩ resistors; VCC = 50 V; IO = 600 mA sink capability. | Designed for low-side switching; requires no external base resistor but lacks PNP sourcing topology. | Select when driving relays from microcontroller ground-referenced outputs and space-constrained layouts favor resistor integration. |
| DMN3028LSD-13 | Single N-channel MOSFET (30 V, 4.5 A, 28 mΩ); no integrated diode; requires external TVS/flyback diode. | Higher current capacity and lower conduction loss, but adds component count and layout complexity. | Choose for high-efficiency, high-cycle-life relay control where thermal performance outweighs BOM simplicity. |
Compared with DRDNB16W-7, DRDP006W-7 offers high-side sourcing and external bias flexibility; versus DMN3028LSD-13, it trades off RDS(on) for integrated protection and smaller footprint - critical for multi-channel relay boards with tight spacing.

FAQ
What is the maximum continuous relay coil current supported by DRDP006W-7?
The DRDP006W-7 PNP transistor supports up to -600 mA IC at TA = 25°C, but practical continuous relay coil current is limited to ~350 mA due to 200 mW total power dissipation and thermal resistance of 625 °C/W. Derating is required above 25°C ambient - e.g., ≤200 mA at 85°C.
Can DRDP006W-7 replace a standalone transistor and separate diode in an existing design?
Yes - DRDP006W-7 directly replaces discrete PNP transistors (e.g., MMBT3906) and fast-switching diodes (e.g., BAS16) in relay driver circuits. Pin 4 serves as both collector and diode cathode; external R1/R2 biasing must match original base drive requirements, and NC Pin 5 should remain unconnected.
Is DRDP006W-7 qualified for automotive applications?
DRDP006W-7 is manufactured in IATF 16949-certified facilities and meets RoHS 3 and halogen-free "Green" standards. While not AEC-Q101 certified out-of-box, Diodes Incorporated confirms PPAP capability and change control support for automotive programs - qualification testing must be performed per customer-specific requirements.
How does the integrated diode differ from standard 1N4148 in relay flyback protection?
The integrated diode has 4.0 ns trr, 75 V VRWM, and 4.0 pF CT - significantly faster and lower-capacitance than 1N4148 (4 ns trr, 100 V VRWM, ~4 pF). Its monolithic integration eliminates parasitic inductance from discrete placement, improving EMI suppression and voltage clamping consistency.
