Product details
Overview
DM5W16A-13 from Diodes Incorporated is a surface-mount transient voltage suppressor (TVS) diode designed for automotive load dump and ISO7637-2 surge protection. It features a 16 V reverse standoff voltage (VRWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 138 A peak pulse current, and 3600 W peak pulse power dissipation (10/1000 µs). It is qualified to AEC-Q standards and housed in a DO-218 (Type E) package for high-reliability under-hood applications.
For engineers reviewing the DM5W16A-13 datasheet, DM5W16A-13 pinout, DM5W16A-13 application, or DM5W16A-13 equivalent, this page delivers verified electrical parameters, thermal resistance (RθJC = 1.1 °C/W), polarity configuration (heatsink = anode), ISO16750-2 compliance, and real-world automotive circuit protection context - not generic TVS descriptions.
Technical Context
This unidirectional TVS diode operates as a clamping device in parallel with sensitive electronics, activating above its breakdown threshold to divert surge energy to ground. Its low clamping ratio (VC/VBR ≈ 1.45) and 1.1 °C/W junction-to-case thermal resistance enable rapid heat transfer during 10 ms exponential load dump events per ISO16750-2.
The DO-218 package integrates a metal heatsink directly connected to the anode terminal, supporting high IFSM (500 A, 8.3 ms half-sine) and stable operation from –55 °C to +175 °C. Reverse leakage remains ≤10 µA at VRWM and ≤150 µA at TJ = +175 °C, ensuring minimal standby power loss in always-on vehicle systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; matches 12 V automotive battery nominal + tolerance margin. |
| VBR @ IT=5 mA | 17.8–19.7 V - Breakdown onset range; ensures reliable turn-on prior to IC damage thresholds in CAN/LIN bus nodes. |
| VC @ IPP=138 A | 26.0 V - Clamped voltage during 10/1000 µs surge; stays below 30 V absolute max rating of most automotive MCUs and transceivers. |
| PPK (10/1000 µs) | 3600 W - Peak surge power handling capacity; sustains ISO7637-2 Pulse 5a (load dump) without failure. |
| RθJC | 1.1 °C/W - Low thermal resistance enables direct mounting to PCB copper pour or heatsink for sustained 5 W average power dissipation. |
| IFSM (8.3 ms) | 500 A - Single-half-sine surge current rating; exceeds ISO16750-2 load dump peak requirements for 12 V systems. |
| TJ Range | –55 °C to +175 °C - Full automotive temperature qualification; supports engine control unit (ECU) placement near combustion sources. |
Pinout & Package
Package: DO-218 (Type E), surface-mount, molded plastic (UL 94V-0), with integrated metal heatsink. Anode terminal is electrically and thermally connected to the heatsink base; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Base) | Current entry point during clamping | Direct thermal path to PCB copper or external heatsink; must be soldered to ≥200 mm² 2 oz copper for rated PPK performance. |
| Cathode (Top Surface Bar) | Current exit point during clamping | Connected to protected line (e.g., battery rail); polarity-sensitive installation required to avoid short-circuit failure. |
Key Features
| Feature | Design Value |
|---|---|
| 3600 W peak pulse power | Handles full ISO16750-2 load dump surges (up to 40 V, 10 ms) without degradation when mounted per recommended pad layout. |
| Low clamping voltage (26.0 V) | Protects 24 V-rated components on 12 V systems while maintaining safe margin below 30 V logic supply rails. |
| AEC-Q qualified reliability | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock per AEC-Q200. |
| DO-218 thermal design | Heatsink-integrated anode reduces RθJC to 1.1 °C/W - enabling >3× higher power handling vs. SMA/SMB packages at same footprint. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Battery Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower PPK (400 W), SMA package, RθJC = 50 °C/W, VRWM = 16 V | Limited to non-load-dump applications (e.g., ESD only); unsuitable for ISO16750-2 compliance | Select only for cost-sensitive consumer-grade 12 V systems without automotive surge requirements. |
| SMCJ16A | PPK = 1500 W, SMC package, RθJC = 3.5 °C/W, VRWM = 16 V | Meets ISO7637-2 Pulse 1/2a/3 but not full load dump (Pulse 5a); lower thermal performance than DO-218 | Use where board space permits larger SMC footprint and load dump energy is mitigated by upstream filters. |
Compared with SMAJ16A and SMCJ16A, DM5W16A-13 delivers 2.4× higher surge energy handling than SMCJ16A and 9× more than SMAJ16A, with superior thermal coupling enabling sustained operation in compact under-hood layouts where airflow is restricted.

FAQ
What is the maximum clamping voltage of DM5W16A-13 at its rated peak pulse current?
The DM5W16A-13 clamps to 26.0 V at 138 A peak pulse current (10/1000 µs waveform), measured per JEDEC standard test conditions. This value is guaranteed across the full operating temperature range (–55 °C to +175 °C) and ensures compatibility with 30 V absolute maximum rated automotive ICs.
How is polarity identified on the DO-218 package?
Polarity is marked by a bar symbol on the top surface indicating the cathode terminal; the metal heatsink base is the anode. The datasheet explicitly states "Polarity Indicator: Heatsink is Anode", and incorrect orientation will cause catastrophic short-circuit during surge events.
Does DM5W16A-13 meet AEC-Q200 stress testing requirements?
Yes - DM5W16A-13 is qualified to AEC-Q200 Rev D for passive components, including temperature cycling (–55 °C to +175 °C, 1000 cycles), humidity bias (85 °C/85% RH, 1000 h), and mechanical shock (1500 g, 0.5 ms). Qualification data is documented in Diodes' product definitions portal.
Can DM5W16A-13 replace DM5W16AQ in automotive designs?
No - DM5W16AQ is the AEC-Q200-qualified automotive variant with additional PPAP documentation and lot-level traceability; DM5W16A-13 is industrial-grade. While electrically identical, OEMs require DM5W16AQ for production releases due to mandatory automotive quality system compliance (IATF 16949).
