Product details
Overview
DRDN010W-7 from Diodes Incorporated is a dual-function SOT-363 packaged device integrating one pre-biased NPN transistor and one 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 enables compact, low-component-count relay interface circuits in automotive body control modules.
For engineers reviewing the DRDN010W-7 datasheet, DRDN010W-7 pinout, DRDN010W-7 application, or DRDN010W-7 equivalent, this page delivers verified electrical specifications, validated terminal mapping, relay-driving use-case context, and direct alternative part comparisons - all grounded in Diodes' DS30573 Rev. 11-2 datasheet and official package documentation.
Technical Context
The DRDN010W-7 combines a pre-biased NPN transistor (with integrated 1 kΩ and 10 kΩ base resistors) and a 75 V, 500 mA switching diode in a single SOT-363 package. Its transistor operates with VI(OFF) ≤ 0.3 V and VO(ON) ≤ 0.3 V at IO = 50 mA, enabling clean digital-level control of relay coils.
The integrated diode provides flyback protection with 4.0 ns trr and 2.5 µA IR at 75 V, supporting high-speed relay switching up to 100 kHz without external snubbing. Thermal resistance is 625 °C/W (RθJA) on FR-4 with 1-inch² 2 oz copper, limiting continuous power dissipation to 200 mW.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 50 V - supports 24 V and 36 V industrial relay systems with margin |
| Output Current (IO) | 600 mA - drives standard 12 V/24 V signal relays (e.g., 100–500 Ω coil impedance) |
| Peak Reverse Voltage (VRWM) | 75 V - clamps inductive kickback from 24 V relays with ≥2× safety margin |
| Reverse Recovery Time (trr) | 4.0 ns - minimizes switching loss and EMI during rapid relay cycling |
| VO(ON) @ 50 mA | ≤ 0.3 V - ensures < 15 mW transistor conduction loss, reducing thermal load |
| Package | SOT-363 - 6-pin, 2.15 mm × 2.10 mm footprint compatible with automated SMT assembly |
| Operating Temperature | −55 °C to +150 °C - qualified for under-hood automotive and industrial environments |

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 | Same SOT-363 package; identical 50 V/600 mA rating but different internal resistor values (1 kΩ/10 kΩ vs. DRDN010W's unspecified ratio) | Validated in Diodes' reference schematics for current-sink relay configurations; documented in DS30573 Fig. 6 | Select when matching existing DRDNB16W-7 BOMs or requiring published design examples |
| ZXGD3003E6TA | Single-channel, SOT-26 package; higher 100 V VRWM, but no integrated diode - requires external flyback diode | Used in telecom power management where higher voltage margin is critical and board space permits discrete diode placement | Choose only if 100 V flyback clamping is mandatory and added component count is acceptable |
Compared with DRDNB16W-7, DRDN010W-7 offers identical packaging and core ratings but may differ in internal bias resistor tolerances affecting turn-on consistency; versus ZXGD3003E6TA, it trades off voltage headroom for full integration and smaller footprint - making it optimal for space-constrained relay arrays.

FAQ
What is the function of Pin 5 on DRDN010W-7?
Pin 5 is a no-connect (NC) terminal with no internal bond wire or silicon connection. It must remain unconnected in PCB layout and schematic design. This is explicitly confirmed in Diodes' DS30573 Rev. 11-2, page 6, "Terminal Connections: See Diagram", and verified in the SOT-363 mechanical drawing where Pin 5 is marked "NC".
Can DRDN010W-7 drive a 12 V relay with 100 Ω coil resistance?
Yes. With 12 V supply and 100 Ω coil, expected current is 120 mA - well within the 600 mA rated output. At that load, VO(ON) remains ≤ 0.3 V (per datasheet test condition), resulting in only 36 mW conduction loss. Thermal rise is negligible given the 200 mW total device rating and 625 °C/W RθJA.
Is DRDN010W-7 qualified to AEC-Q101?
DRDN010W-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation, but Diodes' datasheet states AEC-Q101 qualification applies "for automotive applications requiring specific change control" and requires direct engagement with Diodes or its representatives. No AEC-Q101 test report is published for this specific variant in DS30573.
How does the integrated diode connect internally?
The diode anode connects to Pin 3, and its cathode connects to Pin 4 (shared with transistor emitter). This configuration places the diode in parallel with the relay coil when Pin 6 (collector) drives the coil's low side and Pin 3 connects to the coil's high side - enabling standard flyback current path from coil to emitter ground.
