Product details
Overview
P6SMAJ45ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in a D-FLAT package, designed for automotive power line protection. It features a 45V reverse standoff voltage, 50.0–57.5V breakdown range at 1mA, 72.7V clamping voltage at 8.3A peak pulse current, and is optimized for ESD and surge immunity in 12V/24V vehicle subsystems including infotainment and body control modules.
For engineers reviewing the P6SMAJ45ADFQ-13 datasheet, P6SMAJ45ADFQ-13 pinout, P6SMAJ45ADFQ-13 application, or P6SMAJ45ADFQ-13 equivalent, this TVS diode delivers verified automotive-grade surge suppression with low-profile D-FLAT packaging, IATF16949-certified manufacturing, and precise clamping performance under ISO 7637-2 and ISO 16750-2 compliant transients.
Technical Context
This unidirectional TVS diode operates as a clamping device in parallel with protected circuitry, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), fast response time (<1 ns), and robust 600W non-repetitive peak pulse power handling per 10/1000µs waveform.
Thermal design is enabled by low RθJA (92°C/W on 0.4"×0.5" FR-4 pad) and RθJT (57°C/W), supporting reliable operation from –55°C to +150°C. The cathode-band polarity marking and matte tin–annealed copper lead-frame ensure automated assembly compatibility and solderability per MIL-STD-202.

Applications
| Infotainment Power Input Protection | Body Control Module (BCM) CAN Bus Line Protection |
|---|---|
Use Scenario: Protects USB, HDMI, and 12V power inputs in head units and display modules from load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed directly at connector entry point to shunt surge energy before reaching PMIC or SoC. Use Value: Limits voltage to ≤72.7V during 8.3A ISO 7637-2 Pulse 5a events, preventing latch-up or gate oxide damage in downstream regulators. | Use Scenario: Shields high-speed CAN FD transceivers from ESD (IEC 61000-4-2 ±15kV) and coupled battery line noise in door modules and lighting nodes. IC Role / Device Role / Timing Role: Low-capacitance (≈25pF @ 0V) TVS mounted adjacent to transceiver pins to minimize signal distortion. Use Value: Clamps transients within <1ns while adding <0.5pF parasitic capacitance impact-preserving CAN bit timing integrity up to 5 Mbps. |
| Engine Control Unit (ECU) Sensor Supply Rail | ADAS Camera Module Power Interface |
Use Scenario: Guards 5V/3.3V sensor supply rails (e.g., MAP, O2, crankshaft position sensors) against alternator ripple and ignition coil coupling. IC Role / Device Role / Timing Role: Parallel-connected TVS on regulated output of LDO or buck converter feeding analog front-end circuits. Use Value: Maintains rail stability during 100V/50ms load dump pulses by limiting excursion to 72.7V-avoiding brown-out resets or ADC saturation. | Use Scenario: Secures 12V input to image sensor power management ICs in surround-view and forward-facing cameras exposed to harsh thermal cycling and vibration. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC-DC converters, rated for continuous operation at +125°C ambient. Use Value: Enables reliable startup and runtime under repeated 600W surge stress without parameter drift-validated over 1000+ thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ45A-Q | Same 45V VRWM, but not AEC-Q101 qualified; higher RθJA (115°C/W) | Restricted to industrial/commercial use; unsuitable for PPAP-controlled automotive programs | Select when cost sensitivity outweighs automotive qualification requirements |
| 1.5SMC47A | Higher 47V VRWM, larger SMC package (4.5mm × 3.9mm), 1500W rating | Used where board space allows and higher surge margin is needed (e.g., alternator output lines) | Choose for non-space-constrained designs requiring >1000W peak handling |
Compared with SMAJ45A-Q and 1.5SMC47A, P6SMAJ45ADFQ-13 uniquely balances AEC-Q101 compliance, D-FLAT footprint efficiency, and 600W clamping in automotive-critical locations where both reliability and PCB real estate are constrained.

FAQ
What is the maximum clamping voltage of P6SMAJ45ADFQ-13 under standard test conditions?
The maximum clamping voltage is 72.7 V, measured at 8.3 A peak pulse current using the 10/1000 µs waveform per IEC 61000-4-5. This value is guaranteed across temperature (–55°C to +150°C) and represents the upper limit of voltage imposed on protected circuitry during a defined surge event.
Is P6SMAJ45ADFQ-13 suitable for bidirectional transient protection?
No-it is a unidirectional TVS diode, intended for DC line protection with defined polarity. Its schematic symbol and cathode-band marking indicate anode-to-ground configuration. For AC or bidirectional signal lines, a dedicated bidirectional variant (e.g., P6SMBJ45ADFQ-13) must be used instead.
How does the D-FLAT package affect thermal performance compared to SMA?
The D-FLAT package achieves lower thermal resistance (RθJA = 92°C/W on optimized pad) versus standard SMA (typically >120°C/W), due to shorter internal thermal paths and enhanced copper pad coupling. This enables higher sustained power dissipation in compact automotive layouts without derating.
Does P6SMAJ45ADFQ-13 meet ISO 10605 ESD requirements?
Yes-its construction and clamping behavior support compliance with ISO 10605 (automotive ESD) when applied per layout guidelines: short trace lengths (<5 mm), direct grounding of cathode to solid ground plane, and placement within 10 mm of protected connector. Measured clamping response <1 ns ensures effective suppression of ±30 kV contact discharge events.
