Product details
Overview
P6SMAJ36ADF-13 from Diodes Incorporated is a 600W surface-mount transient voltage suppressor (TVS) diode designed for unidirectional overvoltage protection in DC power rails and signal lines. It features a reverse standoff voltage of 36 V, breakdown voltage range 40.0–46.0 V at 1.0 mA test current, clamping voltage of 58.1 V at 10.3 A peak pulse current, and D-FLAT package for space-constrained PCB layouts-used in industrial power supplies and automotive body electronics.
For engineers reviewing the P6SMAJ36ADF-13 datasheet, P6SMAJ36ADF-13 pinout, P6SMAJ36ADF-13 application, or P6SMAJ36ADF-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak pulse current capability under IEC 61000-4-5 surge conditions, thermal resistance to PCB copper pad area, and RoHS-compliant green packaging for high-reliability manufacturing.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains non-conductive below 36 V reverse standoff voltage and rapidly avalanches above its 40.0–46.0 V breakdown threshold to limit transient energy. Its glass-passivated junction ensures stable leakage (<1 µA at VRWM) and repeatable clamping performance across temperature.
The device uses a low-profile D-FLAT package with cathode band polarity marking, optimized for automated placement and reflow soldering. Thermal resistance is 57 °C/W (junction-to-terminal, small pad) or 92 °C/W (junction-to-ambient), directly linking PCB layout to sustained surge handling capability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-Q | Same 36 V VRWM, but SMA package (larger footprint, higher RθJA = 115 °C/W) | Less suitable for ultra-dense layouts; lower thermal performance on minimal copper | Select when legacy board design uses SMA pads or when cost sensitivity outweighs size constraints |
| 1.5SMC36A | 600 W rating, same clamping (58.1 V), but SMC package (7.1 mm × 6.2 mm) | Higher mounting height and larger area; better for high-volume manual inspection | Prefer for high-power industrial systems where thermal mass and mechanical robustness are prioritized |
Compared with SMAJ36A-Q and 1.5SMC36A, P6SMAJ36ADF-13 delivers identical electrical protection in a 40% smaller footprint and 35% lower junction-to-terminal thermal resistance-enabling tighter layout control and improved surge endurance in space-limited designs.

FAQ
What is the maximum peak pulse current rating for P6SMAJ36ADF-13?
The maximum peak pulse current (IPP) is 10.3 A under the standardized 10 × 1000 µs waveform defined in IEC 61000-4-5. This value is measured at TA = +25°C with specified test conditions and correlates directly to the 58.1 V clamping voltage and 600 W peak power rating.
Does P6SMAJ36ADF-13 support bidirectional transient suppression?
No, P6SMAJ36ADF-13 is a unidirectional TVS diode. Its schematic symbol and internal structure include a single PN junction with cathode band marking, enabling clamping only for positive transients relative to ground. For bidirectional protection, a separate part such as P6SMBJ36CA-13 must be used.
How does the D-FLAT package affect thermal performance compared to SMA?
The D-FLAT package achieves 57 °C/W junction-to-terminal thermal resistance (on 0.4" × 0.5" copper pad), significantly lower than the 64 °C/W of standard SMA packages. This enables faster heat dissipation into the PCB, improving reliability during repetitive surge events and allowing tighter layout spacing without derating.
Is P6SMAJ36ADF-13 qualified for automotive applications?
While not AEC-Q200 qualified, P6SMAJ36ADF-13 meets key automotive surge requirements including ISO 7637-2 Pulse 1, 2a, 3a/b, and 5a when properly mounted. Its -55°C to +150°C operating temperature range, low leakage (<1 µA), and robust glass-passivated die make it widely deployed in non-safety-critical automotive modules like body control and infotainment power rails.
