Product details
Overview
P6SMAJ5.0ADFQ-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 5.0V reverse standoff voltage, 6.4–7.23V breakdown range at 10mA, 9.2V clamping voltage at 65.2A peak pulse current, and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the P6SMAJ5.0ADFQ-13 datasheet, P6SMAJ5.0ADFQ-13 pinout, P6SMAJ5.0ADFQ-13 application, or P6SMAJ5.0ADFQ-13 equivalent, key selection criteria include clamping performance under 10/1000µs transients, thermal resistance on FR-4 PCBs, D-FLAT package footprint compatibility, and automotive PPAP readiness.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below 5.0V VRWM and rapidly transitions to low-impedance conduction above its 6.4V minimum breakdown threshold. Its glass-passivated junction ensures stable leakage (<800µA at 5.0V) and repeatable clamping behavior across temperature.
The device delivers 600W peak pulse power handling per 10×1000µs waveform with a 9.2V clamping voltage at 65.2A IPP, enabling robust protection against ISO 7637-2 Load Dump and IEC 61000-4-5 surge events. Thermal design relies on its 57°C/W RθJT (on 0.4"×0.5" copper pad) and 92°C/W RθJA ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Sustains single 10×1000µs surges without failure |
| Clamping Voltage | 9.2V @ 65.2A - Limits downstream IC voltage during surge |
| Breakdown Voltage | 6.4–7.23V @ 10mA - Ensures reliable turn-on before system damage |
| Reverse Standoff | 5.0V - Blocks normal operation voltage while allowing margin |
| Leakage Current | <800µA @ 5.0V - Minimizes standby power loss in battery systems |
| Package | D-FLAT - 2.25–2.95mm width, 3.95–4.60mm length, 0.90–1.10mm height |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Protected Line Anode Connection | Connected to protected line (e.g., 5V rail); absorbs positive transients |
| 2 (Anode) | Ground Reference | Tied to system ground; completes clamping path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive under-hood use with full PPAP support |
| Glass Passivated Junction | Ensures stable VBR and low leakage over 150°C operating range |

Applications
| Automotive Body Control Module (BCM) | Infotainment Power Supply Protection |
|---|---|
Use Scenario: Protects 5V microcontroller supply rails from load dump and jump-start transients in BCMs. IC Role / Device Role / Timing Role: Shunt-clamping TVS placed between 5V rail and chassis ground. Use Value: Clamps to 9.2V within nanoseconds, preventing MCU brownout or latch-up during ISO 7637-2 Test Pulse 5a. | Use Scenario: Safeguards USB and HDMI interface power inputs in head units exposed to ESD and cable discharge. IC Role / Device Role / Timing Role: Unidirectional TVS on +5V VBUS line upstream of USB controller. Use Value: Sub-100ns response and 600W surge rating suppresses IEC 61000-4-2 contact ESD (±15kV) without degrading signal integrity. |
| Engine Control Unit (ECU) Sensor Interface | ADAS Camera Power Input |
Use Scenario: Shields LIN bus transceivers and analog sensor inputs (e.g., MAP, TPS) from coupled transients. IC Role / Device Role / Timing Role: TVS on sensor supply line (5V or 3.3V) with low capacitance (≈200pF at 0V). Use Value: 200pF typical capacitance avoids signal distortion on 20kHz LIN signals while providing 65A surge immunity. | Use Scenario: Protects 12V input of image sensor modules in rear-view and surround-view cameras. IC Role / Device Role / Timing Role: Primary surge clamp on camera module's main power entry point. Use Value: Withstands repeated 10×1000µs surges up to 600W, meeting OEM requirements for 10-year field reliability in ADAS applications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-Q | Same 5.0V VRWM, 600W rating, but not AEC-Q101 qualified; RθJA = 115°C/W (larger pad) | Limited to industrial/commercial use; lacks PPAP documentation and IATF16949 traceability | Select when automotive qualification is unnecessary and cost sensitivity outweighs long-term supply assurance |
| 1.5SMC5.0A | Higher 1500W rating, DO-214AB package (larger footprint), VF = 3.5V, same clamping (9.2V) | Requires board redesign; better for higher-energy surges but less space-efficient | Choose only if system-level testing confirms need for >600W capability and PCB area permits larger package |
Compared with SMAJ5.0A-Q and 1.5SMC5.0A, P6SMAJ5.0ADFQ-13 uniquely balances AEC-Q101 compliance, D-FLAT space efficiency, and verified 600W clamping-making it optimal for volume automotive ECUs where footprint, qualification, and thermal performance are jointly constrained.

FAQ
What is the maximum operating temperature for P6SMAJ5.0ADFQ-13?
The device supports continuous operation from –55°C to +150°C junction temperature. Its thermal resistance values (RθJT = 57°C/W on 0.4"×0.5" pad) allow sustained 1.0W dissipation at TL = +25°C, with derating above ambient per Figure 6 in DS42231 Rev. 2–2.
Does P6SMAJ5.0ADFQ-13 meet ISO 7637-2 Pulse 5a requirements?
Yes-it clamps to 9.2V at 65.2A under 10×1000µs waveform, which exceeds the 60V/30A test profile of ISO 7637-2 Pulse 5a when applied to 5V systems. Its 600W rating and fast response ensure compliance when mounted per recommended D-FLAT pad layout.
How does the D-FLAT package affect PCB layout versus SMA?
D-FLAT measures 2.25–2.95mm × 3.95–4.60mm × 0.90–1.10mm-~30% shorter and ~40% lower than standard SMA. This reduces parasitic inductance and improves surge response, but requires tighter stencil aperture control due to its flat, low-profile leads.
Is P6SMAJ5.0ADFQ-13 compatible with lead-free reflow profiles?
Yes-the device uses matte tin annealed terminations and is rated for JEDEC J-STD-020 moisture sensitivity Level 1. It withstands peak reflow temperatures up to 260°C for 30 seconds, fully compliant with IPC/JEDEC J-STD-020D.1 Class 3 assembly requirements.
