Product details
Overview
P6SMAJ15ADFQ-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for automotive-grade overvoltage protection in DC power lines and signal paths. It features a 15V reverse standoff voltage, 24.4V max clamping voltage at 24A peak pulse current, and AEC-Q101 qualification for under-hood and infotainment system applications.
For engineers reviewing the P6SMAJ15ADFQ-13 datasheet, P6SMAJ15ADFQ-13 pinout, P6SMAJ15ADFQ-13 application, or P6SMAJ15ADFQ-13 equivalent, this device delivers verified surge immunity per ISO 7637-2 and IEC 61000-4-5 in compact D-FLAT packaging with cathode-band polarity marking and automotive PPAP support.
Technical Context
This unidirectional TVS diode operates as a clamping device in parallel with sensitive circuitry, conducting only when reverse voltage exceeds its 16.7–19.2V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1µA at 15V), critical for battery-backed systems.
With 600W peak pulse power handling (10/1000µs waveform), 64°C/W junction-to-terminal thermal resistance on FR-4, and 115°C/W junction-to-ambient rating, it sustains repeated transients without thermal runaway in constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - withstands ISO 7637-2 Pulse 1 (−100V/2Ω) and Pulse 3a/b without failure |
| Reverse Standoff Voltage | 15V - blocks normal operating voltage while remaining fully inactive below threshold |
| Breakdown Voltage Range | 16.7–19.2V @ 1mA - tight VBR window enables precise overvoltage triggering |
| Max Clamping Voltage | 24.4V @ 24A - limits downstream IC stress to safe levels during 10/1000µs surges |
| Leakage Current | ≤1.0µA @ 15V - negligible standby power loss in always-on automotive modules |
| Package | D-FLAT - 2.25–2.95mm width, 3.95–4.60mm length, 0.90–1.10mm height for high-density routing |
Pinout & Package
Package: D-FLAT surface-mount package with cathode band marking; terminals are anode (pin 2) and cathode (pin 1); molded plastic case rated UL 94V-0; weight ≈0.035g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode Band) | Transient return path | Connected to ground or low-impedance reference; carries full surge current during clamping |
| 2 (Anode) | Protected line input | Connected to supply rail or signal line; voltage referenced to cathode during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive temperature range (−55°C to +150°C) and humidity cycling per IATF16949 manufacturing |
| Glass-passivated die | Eliminates moisture-induced parameter drift and improves long-term VBR stability in harsh environments |
| Low-profile D-FLAT | Reduces board footprint by 40% vs. SMA; enables placement near connectors and ESD-sensitive ICs |
| Lead-free & green | RoHS 3 compliant with <900ppm Br/Cl and <1000ppm Sb; compatible with lead-free reflow profiles (J-STD-020 Level 1) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/5A (Vishay) | Same 15V VRWM, but lower 400W PPK; non-AEC-Q101; higher leakage (5µA) | Limited to industrial/commercial use; not PPAP-capable or IATF16949-manufactured | Select only for cost-sensitive non-automotive designs where 600W margin is unnecessary |
| 1.5SMC15A (ON Semiconductor) | Same 15V rating, 600W rating, but SMC package (4.5×7.0mm) - 2.5× larger footprint than D-FLAT | Acceptable for space-tolerant boards; lacks automotive qualification documentation | Choose when board layout allows larger package and AEC-Q101 traceability is not required |
Compared with SMAJ15A-E3/5A and 1.5SMC15A, P6SMAJ15ADFQ-13 uniquely combines AEC-Q101 qualification, D-FLAT miniaturization, and 600W clamping in a single automotive-compliant component-enabling direct integration into space-constrained, safety-critical vehicle ECUs without derating or secondary qualification.

FAQ
What is the maximum clamping voltage of P6SMAJ15ADFQ-13 at rated peak pulse current?
The maximum clamping voltage is 24.4V at 24.0A peak pulse current (10/1000µs waveform), measured per IEC 61000-4-5 test conditions. This value ensures protected downstream ICs remain within absolute maximum ratings during surge events, with no derating required up to +125°C ambient.
Is P6SMAJ15ADFQ-13 suitable for bidirectional transient protection?
No - P6SMAJ15ADFQ-13 is a unidirectional TVS diode, optimized for DC power line protection where polarity is fixed. For AC or bidirectional signal lines, Diodes Incorporated offers the P6SMBJ15CA-13 variant, which provides symmetrical clamping in both directions with identical 24.4V VC.
How does the D-FLAT package improve thermal performance versus standard SMA?
The D-FLAT package reduces thermal resistance to 64°C/W (junction-to-terminal) due to its flat, low-profile copper lead-frame design and direct thermal path to PCB copper. This is 22% lower than standard SMA packages, enabling higher surge repetition rates without exceeding 150°C junction temperature.
Does P6SMAJ15ADFQ-13 require external current limiting for surge protection?
No - as a shunt-type TVS, it operates without series impedance; however, system-level fusing must be sized to clear sustained overcurrents beyond its 60A IFSM rating. Its 1.0W steady-state dissipation supports continuous operation only at voltages below VRWM, not during clamping.
