Product details
Overview
P6SMAJ9.0ADFQ-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 power line and signal line protection. It features a 9.0V reverse standoff voltage, 10.0–11.5V breakdown range at 1.0mA test current, 15.4V max clamping voltage at 39.0A peak pulse current, and <5.0µA reverse leakage at VRWM - enabling robust ESD and surge immunity in 12V automotive systems.
For engineers reviewing the P6SMAJ9.0ADFQ-13 datasheet, P6SMAJ9.0ADFQ-13 pinout, P6SMAJ9.0ADFQ-13 application, or P6SMAJ9.0ADFQ-13 equivalent, this TVS diode supports critical design tasks including ISO 7637-2 pulse suppression, CAN/LIN bus overvoltage hardening, and battery rail transient clamping in engine control units and ADAS sensors.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt clamp during voltage transients, with sub-nanosecond response time and glass-passivated junction construction ensuring stable breakdown behavior across temperature. Its low-profile D-FLAT package enables high-density PCB layouts while maintaining thermal resistance of 57°C/W (junction-to-terminal) on optimized 0.4" × 0.5" copper pads.
The device complies with AEC-Q101 stress testing requirements and is manufactured in IATF16949:2016 certified facilities. It delivers 600W non-repetitive peak pulse power handling per the 10/1000µs waveform, with steady-state power dissipation rated at 1.0W and operating junction temperature spanning −55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - withstands ISO 7637-2 Pulse 1 (−150V/2Ω) and Pulse 3a/b without failure |
| Reverse Standoff Voltage | 9.0V - sets minimum operating voltage threshold before clamping activates on 12V automotive rails |
| Breakdown Voltage Range | 10.0–11.5V @ 1.0mA - ensures reliable turn-on margin above nominal supply under temperature variation |
| Max Clamping Voltage | 15.4V @ 39.0A - limits downstream IC stress during 10/1000µs surges to safe levels for 16V-tolerant receivers |
| Reverse Leakage | <5.0µA @ 9.0V - negligible standby current draw, preserving battery life in always-on modules |
| Thermal Resistance (J–T) | 57°C/W - enables efficient heat transfer to PCB copper when mounted on 0.4" × 0.5" 2oz pad |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A-Q | Same 9.0V VRWM and 15.4V VC, but not AEC-Q101 qualified; JEDEC-standard SMA package (higher profile) | Limited to industrial/commercial use; unsuitable for PPAP-controlled automotive production | Select only for cost-sensitive non-automotive designs where D-FLAT footprint is not required |
| TPSMD9.0 | Higher 600W rating but 16.5V clamping voltage; TO-277 package with higher RθJA (115°C/W) | Less effective clamping margin for 12V systems; requires larger thermal pad area | Prefer only if legacy TO-277 layout compatibility is mandatory and clamping voltage margin allows |
Compared with SMAJ9.0A-Q and TPSMD9.0, the P6SMAJ9.0ADFQ-13 uniquely combines AEC-Q101 compliance, D-FLAT space efficiency, and tight 15.4V clamping - making it the only choice for volume automotive electronics requiring PPAP documentation and compact 12V rail protection.

FAQ
What is the maximum peak pulse current rating for P6SMAJ9.0ADFQ-13?
The P6SMAJ9.0ADFQ-13 is rated for 39.0A peak pulse current (IPP) under the standard 10/1000µs double-exponential waveform. This value is measured at 15.4V clamping voltage and reflects its ability to safely divert transient energy without degradation when applied within specified duty cycle limits (≤4 pulses/minute).
Does P6SMAJ9.0ADFQ-13 support bidirectional transient suppression?
No - P6SMAJ9.0ADFQ-13 is a unidirectional TVS diode, configured to clamp positive transients on a line referenced to ground. Its schematic shows cathode (pin 1) connected to the protected line and anode (pin 2) to ground. For bidirectional protection (e.g., data lines), a dedicated bidirectional variant like P6SMBJ9.0ADFQ-13 would be required.
How does the D-FLAT package improve thermal performance versus standard SMA?
The D-FLAT package reduces junction-to-terminal thermal resistance to 57°C/W (vs. ~80°C/W for SMA) due to its flat, exposed copper leadframe design and optimized solder joint geometry. When mounted on a 0.4" × 0.5" 2oz copper pad, it achieves lower steady-state junction temperatures during repetitive surge events, extending operational lifetime in thermally constrained automotive modules.
Is P6SMAJ9.0ADFQ-13 compatible with lead-free reflow profiles?
Yes - the device uses matte tin annealed terminals and is qualified for standard lead-free reflow profiles (JEDEC J-STD-020, peak temperature up to 260°C). Its moisture sensitivity level is rated at Level 1, meaning it can be stored indefinitely at ambient conditions without baking prior to assembly.
