Product details
Overview
P6SMAJ26ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in D-FLAT package, with 26V reverse standoff voltage, 42.1V max clamping voltage at 14.2A peak pulse current, and <1µA reverse leakage at rated VRWM - deployed for automotive power line surge protection in engine control units and infotainment power rails.
For engineers reviewing the P6SMAJ26ADFQ-13 datasheet, P6SMAJ26ADFQ-13 pinout, P6SMAJ26ADFQ-13 application, or P6SMAJ26ADFQ-13 equivalent, this device is selected for high-reliability 12V/24V automotive systems requiring IATF16949-manufactured, PPAP-capable TVS components with verified clamping performance under ISO 7637-2 pulse 1/2/5a stress conditions.
Technical Context
This unidirectional TVS diode operates as a shunt-type overvoltage protector, triggered when reverse voltage exceeds 26V standoff level and clamping within 1ns to limit transients to ≤42.1V. Its glass-passivated junction ensures stable breakdown behavior across -55°C to +150°C operating range.
Designed for automotive-grade robustness, it delivers 600W non-repetitive peak pulse power handling per 10×1000µs waveform, with thermal resistance of 57°C/W (junction-to-terminal) on optimized 0.4"×0.5" FR-4 copper pad - enabling direct integration into compact ECU PCB layouts without external heatsinking.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A-Q | Same 26V VRWM and 42.1V VC, but SMA package (higher profile, 2.2mm height) and no AEC-Q101 qualification | Not approved for automotive production; limited to industrial or consumer designs without PPAP requirements | Select only if cost sensitivity outweighs automotive compliance and board height constraints |
| 1.5SMC27A | 27V VRWM, 43.0V VC, DO-214AB package, 1500W rating - larger footprint and higher clamping voltage | Used where higher surge margin is needed but board space allows larger package | Choose when system-level testing shows 1.5kW pulse immunity is required beyond ISO 7637-2 baseline |
Compared with SMAJ26A-Q and 1.5SMC27A, P6SMAJ26ADFQ-13 uniquely combines AEC-Q101 qualification, D-FLAT low-profile packaging, and precise 26V/42.1V electrical matching - making it the only option for space-constrained, PPAP-mandated automotive ECUs requiring validated IATF16949 traceability.

FAQ
What is the maximum operating temperature for P6SMAJ26ADFQ-13?
The device operates from -55°C to +150°C junction temperature. Its thermal resistance is 57°C/W (junction-to-terminal) when mounted on a 0.4"×0.5" FR-4 board with 2oz copper, allowing sustained operation at full 600W pulse rating without derating below +125°C ambient in properly designed layouts.
Is P6SMAJ26ADFQ-13 compatible with lead-free reflow processes?
Yes - it features matte tin annealed terminals and is rated for standard lead-free reflow profiles (JEDEC J-STD-020, peak 260°C). The D-FLAT package has moisture sensitivity level 1, eliminating bake requirements prior to assembly.
How does the clamping voltage of P6SMAJ26ADFQ-13 compare to its breakdown voltage?
Breakdown occurs at 28.9–33.2V (min/max at 1mA), while clamping is specified at 42.1V under 14.2A 10×1000µs pulse. This ~10V differential ensures robust margin between turn-on and safe limiting, preventing false triggering while guaranteeing downstream IC protection.
Can P6SMAJ26ADFQ-13 be used in bidirectional configurations?
No - it is a unidirectional TVS diode with cathode/anode polarity marking. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional part like P6SMBJ26CA should be selected instead.
