Product details
Overview
P6SMAJ14ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for automotive-grade overvoltage protection. It features a 14V reverse standoff voltage, 15.6–17.9V breakdown range at 1mA, 23.2V max clamping voltage at 25.8A peak pulse current, and <1µA reverse leakage at VRWM - deployed in power line and signal line surge protection for engine control units and infotainment interfaces.
For engineers reviewing the P6SMAJ14ADFQ-13 datasheet, P6SMAJ14ADFQ-13 pinout, P6SMAJ14ADFQ-13 application, or P6SMAJ14ADFQ-13 equivalent, this page delivers verified electrical specs, thermal resistance values, automotive qualification status, and real-world use context - critical for ESD/EMI hardening, ISO 7637-2 compliance, and IATF 16949-aligned production design-in.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt clamp during transient events, with sub-nanosecond response time and 600W non-repetitive peak pulse power handling per 10/1000µs waveform. Its glass-passivated junction ensures stable VBR tolerance and low leakage across -55°C to +150°C operating range.
The device uses a planar silicon junction structure optimized for low dynamic impedance and repeatable clamping performance. Thermal resistance is specified at RθJT = 64°C/W (FR-4, 1"×1", 2oz copper pad) and RθJA = 115°C/W - enabling reliable thermal management in high-density automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 10/1000µs transients without failure in automotive load-dump or ISO 7637-2 Test Pulse 5a. |
| Reverse Standoff Voltage | 14 V - maximum continuous DC or RMS voltage before significant leakage; sets system operating margin. |
| Breakdown Voltage | 15.6–17.9 V @ 1 mA - tight VBR window ensures predictable turn-on during overvoltage events. |
| Clamping Voltage | 23.2 V @ 25.8 A - limits downstream IC stress to safe levels during 10/1000µs surges. |
| Reverse Leakage | <1 µA @ 14 V - negligible standby current impact on battery-sensitive automotive modules. |
| Junction Temp Range | -55 to +150 °C - supports under-hood deployment in ECUs, ADAS sensors, and body control modules. |
Pinout & Package
Package: D-FLAT (low-profile surface-mount), molded plastic case with UL 94V-0 rating, cathode band polarity indicator, and matte tin annealed copper lead-frame.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode-side reference terminal | Connected to protected line; clamps to ground when transient exceeds VBR. |
| 2 (Anode) | Ground reference terminal | Typically tied to chassis or system ground plane; completes clamping path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including PPAP submission and IATF 16949 manufacturing. |
| Glass passivated die | Enhances long-term reliability and moisture resistance in humid under-hood environments. |
| Low profile D-FLAT package | 0.9–1.1 mm height enables placement beneath connectors and in space-constrained modules. |
| Lead-free & halogen-free | RoHS 3 compliant (<900 ppm Br/Cl, <1000 ppm Sb); meets automotive green material requirements. |
Applications
| Engine Control Unit (ECU) Power Input | Infotainment USB Data Lines |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A-Q | Same 14V VRWM and 23.2V VC, but not AEC-Q101 qualified; RθJA = 125°C/W (higher thermal resistance). | Limited to industrial/commercial use; unsuitable for PPAP or automotive production release. | Select only for cost-sensitive non-automotive designs where qualification and thermal margin are secondary. |
| 1.5SMC14A | Higher 1500W rating, DO-214AB package (larger footprint), 23.2V VC, but no AEC-Q101 certification. | Better surge handling but incompatible with space-constrained D-FLAT layouts; requires rework of PCB land pattern. | Choose when peak power >600W is required and board area permits larger SMC package. |
Compared with SMAJ14A-Q and 1.5SMC14A, the P6SMAJ14ADFQ-13 uniquely combines AEC-Q101 qualification, D-FLAT space efficiency, and validated thermal performance for automotive Tier-1 production - making it the only option meeting both IATF 16949 sourcing and under-hood thermal constraints.

FAQ
What is the maximum clamping voltage of P6SMAJ14ADFQ-13 at rated peak pulse current?
The maximum clamping voltage is 23.2 V at 25.8 A peak pulse current (IPP), measured using the standard 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value ensures downstream 3.3V/5V logic remains within absolute maximum ratings during surge events.
Is P6SMAJ14ADFQ-13 suitable for bidirectional transient protection?
No - it is a unidirectional TVS diode intended for DC or single-polarity signal lines. Its schematic shows cathode-anode polarity, and it does not conduct in reverse bias beyond its specified leakage. For AC or bidirectional lines, a symmetric dual-diode configuration or dedicated bidirectional TVS must be used.
How does the D-FLAT package affect thermal performance compared to SMA or SMC packages?
The D-FLAT package offers lower thermal resistance to the PCB (RθJT = 64°C/W on 1"×1" FR-4) due to its flat, exposed copper terminals and minimal standoff height. This improves heat dissipation over taller SMA packages, especially in dense automotive modules where airflow is restricted and ambient temperatures exceed 105°C.
Does P6SMAJ14ADFQ-13 require derating at elevated ambient temperatures?
Yes - peak pulse power must be linearly derated above +25°C ambient, per the datasheet's derating curve. At +125°C, the usable PPK drops to approximately 300W. Designers must verify clamping performance under worst-case thermal conditions using the provided RθJA = 115°C/W value and expected board layout.
