Product details
Overview
DM6W27Q-13 from Diodes Incorporated is a 4600W surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO 7637-2 surge protection. It features a 22V reverse standoff voltage, 40V clamping voltage at 65A peak pulse current, and AEC-Q101 qualification for under-hood applications such as engine control units and body control modules.
For engineers reviewing the DM6W27Q-13 datasheet, DM6W27Q-13 pinout, DM6W27Q-13 application, or DM6W27Q-13 equivalent, key selection criteria include ISO16750-2 Pulse A/B compliance, DO-218 package thermal performance, 1.1°C/W junction-to-case thermal resistance, and 600A 8.3ms forward surge rating in automotive power rail protection.
Technical Context
This unidirectional TVS diode uses glass-passivated silicon construction to withstand repetitive load dump transients up to 4600W (10/1000µs) and 3600W (10/10000µs). Its low 0.99V forward voltage at 6.0A enables minimal conduction loss during sustained overvoltage events.
The device operates across –55°C to +175°C with a Zener voltage temperature coefficient of 36mV/°C and exhibits <0.5µA reverse leakage at 22V VRWM. Its DO-218 (Type E) package provides 1.1°C/W thermal resistance from junction to case, enabling high-power dissipation without external heatsinking in constrained automotive layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower 400W peak power, SMA package, 1.5°C/W RθJC, 30A IPP | Not qualified to AEC-Q101; limited to non-automotive or low-energy surge environments | Select when cost sensitivity outweighs automotive qualification and surge energy requirements |
| SMCJ22A | 1500W peak power, SMC package, 2.0°C/W RθJC, 65A IPP, same VRWM | Lacks ISO16750-2 Pulse A/B validation; requires system-level requalification for load dump | Choose only if board space allows larger SMC footprint and full automotive certification is not mandated |
Compared with SMAJ22A and SMCJ22A, DM6W27Q-13 delivers 3× higher surge energy handling, certified automotive qualification, and superior thermal performance in the compact DO-218 package-making it the only option for production-grade 12V automotive power rail protection meeting OEM load dump specifications.

FAQ
What is the clamping voltage of DM6W27Q-13 at its rated peak pulse current?
The DM6W27Q-13 clamps to a maximum of 40V at 65A peak pulse current (10/1000µs waveform), as specified in the Electrical Characteristics table. This value is measured under standardized transient conditions and ensures downstream 40V-rated components remain within safe operating limits during load dump events.
Can DM6W27Q-13 be used in 24V automotive systems?
No-DM6W27Q-13 is rated for 22V reverse standoff voltage and optimized for 12V nominal systems. For 24V applications, Diodes offers the DM6W33Q (33V VRWM) and DM6W36Q (36V VRWM), which share identical DO-218 packaging, AEC-Q101 qualification, and 4600W surge capability.
How does the DO-218 package improve thermal performance over SMA or SMC packages?
The DO-218 (Type E) package features a large metal anode tab that serves as both electrical terminal and thermal path, achieving 1.1°C/W junction-to-case resistance-nearly half that of SMC (2.0°C/W) and significantly better than SMA (1.5°C/W). This allows higher sustained power dissipation without external heatsinking.
Is DM6W27Q-13 compliant with PPAP requirements for automotive production?
Yes-DM6W27Q-13 is PPAP capable and manufactured in IATF 16949 certified facilities. Diodes provides full PPAP documentation including part submission warrant, design records, process flow diagrams, PFMEA, control plans, and measurement system analysis upon request for qualified automotive customers.
