Product details
Overview
DM5W16AQ-13 from Diodes Incorporated is a 3600W 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 16V reverse standoff voltage (VRWM), 26.0V max clamping voltage at 138A peak pulse current (10/1000µs), and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the DM5W16AQ-13 datasheet, DM5W16AQ-13 pinout, DM5W16AQ-13 application, or DM5W16AQ-13 equivalent, this device delivers verified 3600W peak pulse power dissipation, low thermal resistance (RθJC = 1.1°C/W), and compliance with ISO16750-2 Pulse A/B and ISO7637-2 Pulse 1/2a/3a/3b surge waveforms in automotive power rail protection.
Technical Context
This unidirectional TVS diode operates with anode-connected heatsink polarity and exhibits sharp avalanche breakdown at 17.8–19.7V (VBR @ 5mA). Its low clamping ratio (VC/VRWM ≈ 1.63) ensures effective overvoltage suppression during fast transients while maintaining <10µA reverse leakage at VRWM and +25°C.
Thermally optimized for high-power surge handling, it sustains 5W steady-state power at TC = +25°C and derates linearly above that temperature, with junction-to-case thermal resistance of 1.1°C/W enabling efficient heat transfer to PCB copper or external heatsinks in engine control units and body electronics modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3600W (10/1000µs waveform; enables single-event load dump suppression up to 3600W without failure) |
| Reverse Standoff Voltage | 16V (maximum continuous DC operating voltage before clamping begins; matches 12V automotive battery nominal systems) |
| Clamping Voltage | 26.0V @ 138A (limits downstream IC voltage to safe level during ISO16750-2 load dump events) |
| Peak Pulse Current | 138A (10/1000µs; supports robust surge immunity per ISO7637-2 Pulse 5a requirements) |
| Thermal Resistance | RθJC = 1.1°C/W (enables direct thermal coupling to PCB copper pour or heatsink for sustained power dissipation) |
| Operating Temperature | −55°C to +175°C (supports under-hood placement in engine control modules and transmission ECUs) |
| AEC-Q101 Qualified | Yes (certified for automotive-grade reliability including temperature cycling, HTRB, and surge endurance testing) |

Use Scenario: Protects image sensor power supply and serializer ICs from ESD and conducted transients induced by nearby radar or motor actuation. IC Role / Device Role / Timing Role: Secondary-level TVS after primary fuse and LC filter, targeting fast-rising transients (<1ns rise time) near camera module PCB edge. Use Value: Achieves 26.0V clamping at 138A with <1.1°C/W thermal resistance, ensuring stable 12V rail during simultaneous ADAS subsystem activation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower peak power (400W), SMA package, RθJC ≈ 50°C/W, no AEC-Q101 certification | Limited to non-automotive or low-energy surge environments (e.g., industrial I/O) | Select only if cost sensitivity outweighs automotive qualification and thermal performance requirements |
| SMCJ16A | Same DO-214AB package as SMAJ but higher 1500W rating; lacks DO-218's 1.1°C/W thermal path and AEC-Q101 validation | Suitable for commercial-grade 12V systems but not validated for automotive PPAP or temperature cycling | Use where ISO16750-2 compliance is not required and board space permits larger SMC footprint |
Compared with SMAJ16A and SMCJ16A, DM5W16AQ-13 provides 2.4× higher peak power than SMCJ16A and 9× more than SMAJ16A, with certified automotive reliability, superior thermal management, and guaranteed clamping performance across −55°C to +175°C - essential for safety-critical ECU and ADAS power rails.

FAQ
What is the maximum clamping voltage of DM5W16AQ-13 at its rated peak pulse current?
The maximum clamping voltage (VC) is 26.0V at 138A peak pulse current using the 10/1000µs waveform, measured per JEDEC standards. This value is guaranteed across the full operating temperature range of −55°C to +175°C and ensures downstream 24V-rated ICs remain within safe operating limits during load dump events.
How does the DO-218 package improve thermal performance compared to SMA or SMC packages?
The DO-218 (Type E) package features an integrated metal heatsink tab directly bonded to the anode, achieving RθJC = 1.1°C/W - over 45× better than SMA (≈50°C/W) and ~4.5× better than SMC (≈5°C/W). This enables reliable 5W continuous dissipation when mounted on ≥250mm² 2oz copper with thermal vias, critical for under-hood automotive placement.
Is DM5W16AQ-13 suitable for bidirectional surge protection?
No - DM5W16AQ-13 is a unidirectional TVS diode with anode-connected heatsink polarity. It protects against positive-going transients only. For bidirectional protection (e.g., data lines), a separate symmetric TVS array or dual-diode configuration is required; this part must be used with correct polarity orientation relative to the protected rail.
What AEC-Q101 test conditions validate DM5W16AQ-13 for automotive use?
It passes AEC-Q101-004 (HTRB), AEC-Q101-005 (HTGB), AEC-Q101-006 (TCT), and AEC-Q101-011 (surge) tests, including 1000 cycles from −55°C to +175°C and 30-minute high-temperature reverse bias at 125°C. All testing occurs in IATF 16949-certified facilities with full PPAP documentation support for Tier 1 automotive programs.
