Product details
Overview
P6SMAJ48ADFQ-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 interfaces. It features a reverse standoff voltage of 48.0 V, breakdown voltage range of 53.3–61.3 V at 1.0 mA test current, clamping voltage of 77.4 V at 7.7 A peak pulse current, and AEC-Q101 qualification for under-hood and infotainment system applications.
For engineers reviewing the P6SMAJ48ADFQ-13 datasheet, P6SMAJ48ADFQ-13 pinout, P6SMAJ48ADFQ-13 application, or P6SMAJ48ADFQ-13 equivalent, this device delivers verified automotive-grade surge immunity with D-FLAT package thermal performance, precise clamping behavior under 10/1000 µs transients, and low leakage (<1.0 µA at VRWM) for battery-sensitive circuits.
Technical Context
This TVS diode operates as a unidirectional, cathode-anode configured clamp that activates when reverse voltage exceeds its 48.0 V standoff threshold. Its glass-passivated junction ensures stable breakdown characteristics across temperature, while the D-FLAT package enables low-inductance mounting on compact PCBs with minimal thermal resistance (RθJT = 57 °C/W on 0.4" × 0.5" pad).
The device responds to 10/1000 µs waveform transients with a clamping voltage of 77.4 V at 7.7 A, limiting energy dissipation to 600 W non-repetitive pulses. It sustains 60 A forward surge current (8.3 ms half-sine) and maintains <1.0 µA reverse leakage at 48.0 V, supporting low-power always-on systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Handles single high-energy transients without failure, per 10/1000 µs waveform. |
| Reverse Standoff Voltage | 48.0 V - Maximum continuous DC operating voltage before clamping initiates. |
| Breakdown Voltage Range | 53.3–61.3 V @ 1.0 mA - Confirmed activation window ensuring reliable turn-on above nominal rail. |

FAQ
What is the polarity configuration of P6SMAJ48ADFQ-13?
P6SMAJ48ADFQ-13 is a unidirectional TVS diode with cathode (Pin 1) and anode (Pin 2) terminals. The cathode band marks Pin 1, which connects to the line being protected; the anode connects to ground. This configuration provides precise clamping only during reverse overvoltage events, minimizing leakage in normal operation.
How does P6SMAJ48ADFQ-13 differ from standard SMA-package TVS diodes?
Unlike standard SMA devices, P6SMAJ48ADFQ-13 uses the D-FLAT package-0.9–1.1 mm height vs. SMA's ~2.3 mm-enabling lower inductance, better thermal transfer (RθJT = 57 °C/W), and higher surge robustness in constrained automotive layouts. It also carries full AEC-Q101 qualification and PPAP documentation support not found in commercial-grade SMA parts.
Can P6SMAJ48ADFQ-13 be used in bidirectional protection applications?
No-P6SMAJ48ADFQ-13 is strictly unidirectional. For bidirectional protection (e.g., AC lines or differential buses), Diodes offers the P6SMBJ48ADFQ-13 variant. Using this part in reverse-biased configurations risks permanent breakdown due to its asymmetric junction design and lack of forward surge rating in reverse conduction mode.
What is the maximum allowable PCB pad size for optimal thermal performance?
For best thermal performance, use the recommended 0.4" × 0.5" (10.2 mm × 12.7 mm), 2 oz copper pad per the datasheet's Note 8. This layout achieves RθJT = 57 °C/W. Smaller pads increase junction temperature rise during surge events and may reduce lifetime under repetitive stress; larger pads yield diminishing returns beyond 0.6" × 0.6".
