Product details
Overview
DM6W22A-13 from Diodes Incorporated is a 4600W surface-mount transient voltage suppressor (TVS) diode in DO-218 (Type E) package, designed for automotive load dump and ISO7637-2 surge protection. It features 22V reverse standoff voltage, 35.5V max clamping voltage at 130A peak pulse current, and 1.0°C/W junction-to-case thermal resistance - enabling robust overvoltage protection in 12V/24V vehicle power systems.
For engineers reviewing the DM6W22A-13 datasheet, DM6W22A-13 pinout, DM6W22A-13 application, or DM6W22A-13 equivalent, key selection criteria include clamping voltage margin vs. system rail, peak pulse power handling under ISO16750-2 load dump waveforms, thermal derating at elevated case temperatures, and DO-218 mechanical compatibility with high-current PCB layouts.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped crowbar device: it remains high-impedance below 22V VRWM, then avalanches sharply at 24.4–26.9V VBR (5mA test current) to clamp transients. Its 4600W peak pulse rating applies to 10/1000µs waveform, with derated capability down to 3600W for 10/10000µs pulses.
Thermal design is critical: RθJC = 1.0°C/W enables effective heat transfer to heatsink-mounted copper planes, while operation up to +175°C TJ supports under-hood automotive placement. Polarity is fixed - anode connects to heatsink tab, cathode to PCB trace - requiring correct orientation during layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 4600W (10/1000µs); sustains single load dump events per ISO16750-2 without failure |
| Reverse Standoff Voltage | 22V; blocks normal 12V/24V system operation while allowing minimal leakage (<10µA) |
| Clamping Voltage | 35.5V @ 130A; limits downstream IC voltage stress during worst-case surge |
| Junction-to-Case Thermal Resistance | 1.0°C/W; enables direct thermal coupling to heatsink for sustained power dissipation |
| Operating Temperature Range | −55°C to +175°C; qualified for engine compartment and powertrain control module environments |
| Surge Standards Compliance | ISO 7637-2 (Pulse 1, 2a, 3a, 3b) and ISO 16750-2 load dump; validated per automotive requirements |
Pinout & Package
Package: DO-218 (Type E), molded plastic UL 94V-0 housing with matte tin-plated terminals. Heatsink tab serves as anode; cathode is marked by bar symbol on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Positive connection point for clamping path | Must be soldered to large copper pour or external heatsink for thermal management and low-inductance surge return |
| Cathode (Top Marked Pin) | Transient current sink to ground/rail | Connected to protected circuit node; polarity must match schematic to avoid forward conduction during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| High Peak Pulse Power | 4600W rating ensures survival of severe load dump surges without degradation |
| Low Clamping Ratio | VC/VRWM = 1.61 enables tighter voltage margin over protected ICs compared to standard TVS devices |
| Automotive-Qualified Reliability | AEC-Q200-compliant construction with JEDEC-qualified materials for long-term under-hood stability |
| Green Manufacturing | Halogen- and antimony-free, RoHS 3 compliant (Br+Cl <1500ppm, Sb <1000ppm) |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |

FAQ
What is the polarity configuration of DM6W22A-13?
The DM6W22A-13 is a unidirectional TVS diode with anode connected to the heatsink tab and cathode marked by a bar on the top surface. This configuration requires the anode to be tied to the protected power rail (e.g., battery+) and cathode to ground or return path to enable proper clamping action during positive transients.
How does DM6W22A-13 differ from the automotive-qualified DM6W22AQ-13?
The DM6W22AQ-13 variant undergoes additional AEC-Q200 stress testing including extended temperature cycling, board-level vibration, and high-temperature operating life validation. The base DM6W22A-13 meets JEDEC reliability standards but lacks full automotive qualification documentation required for safety-critical modules.
Can DM6W22A-13 be used in 48V mild-hybrid systems?
No - its 22V VRWM and 35.5V clamping voltage are optimized for 12V/24V architectures. For 48V systems, Diodes offers higher-voltage variants such as DM6W43A-13 (43V VRWM, 69.4V clamping), which maintains comparable 4600W pulse capability while matching the higher nominal rail.
What is the recommended PCB layout for thermal performance?
Maximize copper area under the heatsink tab using multiple thermal vias (≥8×0.3mm diameter) to inner-layer ground or dedicated thermal plane. Maintain ≥3.5mm pad width (X dimension) and ≥11.0mm length (X1) per Diodes' suggested layout; avoid solder mask over thermal pads to ensure optimal heat transfer.
