Product details
Overview
P6SMAJ8.0ADFQ-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 and signal line surge protection. It features a reverse standoff voltage of 8.0 V, clamping voltage of 13.6 V at 44.1 A peak pulse current, and fast response time for ESD and lightning-induced transients.
For engineers reviewing the P6SMAJ8.0ADFQ-13 datasheet, P6SMAJ8.0ADFQ-13 pinout, P6SMAJ8.0ADFQ-13 application, or P6SMAJ8.0ADFQ-13 equivalent, this device is selected for robust overvoltage protection in 12 V automotive subsystems where low clamping voltage, high surge capability, and IATF16949-manufactured reliability are required.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device, conducting when reverse voltage exceeds its breakdown threshold (8.89–10.23 V at 1.0 mA test current). Its glass-passivated junction ensures stable leakage performance (<50 µA at 8.0 V) and repeatable clamping behavior under repetitive surge stress.
The device uses a low-inductance D-FLAT package with cathode-band polarity marking and is rated for operation from –55 °C to +150 °C. Thermal resistance is 57 °C/W (junction-to-terminal, on 0.4" × 0.5" PCB pad), enabling effective power dissipation during 600 W non-repetitive 10/1000 µs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 10/1000 µs surges without failure in automotive load-dump or ISO 7637-2 testing |
| Reverse Standoff Voltage | 8.0 V - maximum continuous DC operating voltage before significant leakage begins |
| Breakdown Voltage | 8.89–10.23 V @ 1.0 mA - defines precise conduction onset for predictable clamping margin |
| Clamping Voltage | 13.6 V @ 44.1 A - limits downstream circuit voltage during worst-case surge, protecting 15 V-rated ICs |
| Leakage Current | ≤50 µA @ 8.0 V - ensures minimal standby power loss and no interference with 8 V logic or sensor biasing |
| Operating Temperature | –55 °C to +150 °C - supports under-hood deployment in engine control units and body electronics |
Pinout & Package
Package: D-FLAT (surface-mount, low-profile, 2-terminal SMD package with cathode band marking; dimensions: 4.65 mm × 2.80 mm × 1.10 mm max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Surge return path / clamping node | Connected to protected line (e.g., CAN_H or LIN bus); conducts surge current to ground when overvoltage occurs |
| 2 (Anode) | Reference / ground connection | Directly tied to system ground plane; forms low-inductance return path essential for sub-ns response |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Ensures long-term stability of breakdown voltage and leakage under thermal cycling and humidity exposure |
| AEC-Q101 qualification & IATF16949 manufacturing | Validates reliability for automotive safety-critical modules including ADAS sensors and powertrain ECUs |
| Low-profile D-FLAT package | Reduces board space by >30% vs. SMA packages while maintaining 600 W rating and thermal performance |
| Halogen- and antimony-free "Green" compliance | Meets automotive OEM environmental requirements (<900 ppm Br/Cl, <1000 ppm Sb) without compromising surge robustness |
Applications
| Automotive Body Control Module (BCM) | Infotainment Power Supply Protection |
|---|---|
Use Scenario: Protects 12 V supply rail feeding microcontrollers and driver ICs against load dump and jump-start transients. IC Role / Device Role: Shunt TVS placed between VBAT and GND, clamping spikes to ≤13.6 V to prevent latch-up or damage. Use Value: Enables use of cost-effective 16 V-rated LDOs and avoids need for bulkier active clamp circuits. | Use Scenario: Safeguards USB-C and HDMI power lines in head unit against ESD and hot-plug surges. IC Role / Device Role: Unidirectional TVS on 5 V/9 V/15 V rails, leveraging low capacitance (<100 pF at 0 V) to preserve signal integrity. Use Value: Maintains <10 ns response time and prevents data corruption during ±8 kV contact ESD events per IEC 61000-4-2. |
| CAN FD Transceiver Interface | Electric Power Steering (EPS) Sensor Lines |
Use Scenario: Installed on CAN_H/CAN_L differential pair to absorb common-mode surges induced by motor switching noise. IC Role / Device Role: Paired unidirectional TVS (one per line), referenced to chassis ground, with matched clamping to avoid common-mode offset. Use Value: Limits differential voltage excursion to <27.2 V (2 × 13.6 V), preserving ISO 11898-2 receiver tolerance. | Use Scenario: Shields analog position sensor outputs (e.g., Hall-effect or resolver feedback) from battery transients in EPS motor drivers. IC Role / Device Role: Low-leakage (≤50 µA) TVS on ratiometric 5 V sensor supply, preventing offset drift during quiescent operation. Use Value: Guarantees sensor accuracy remains within ±0.5% full-scale error even after repeated 600 W surge exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-13-F | Non-automotive grade; lacks AEC-Q101 qualification and PPAP capability | Approved only for industrial/commercial use; not suitable for Tier-1 automotive BOMs | Select when cost sensitivity outweighs automotive compliance requirements |
| TPSMAJ8.0A-Q | Same electrical specs but uses DO-214AC package (SMA) instead of D-FLAT; 20% larger footprint | Higher thermal resistance (RθJA = 125 °C/W) limits sustained surge duty cycle | Choose if legacy PCB layout cannot accommodate D-FLAT's 4.65 × 2.80 mm outline |
Compared with SMAJ8.0A-13-F and TPSMAJ8.0A-Q, the P6SMAJ8.0ADFQ-13 uniquely delivers automotive-grade reliability in the smallest footprint, enabling higher-density routing in space-constrained ADAS domain controllers while maintaining full ISO 7637-2 and IEC 61000-4-5 compliance.

FAQ
What is the mounting orientation requirement for P6SMAJ8.0ADFQ-13?
The device must be mounted with the cathode band (marked end) aligned to the protected line (e.g., VBAT or signal line), and the anode terminal soldered directly to a low-impedance ground plane. Incorrect polarity results in no clamping action and potential catastrophic failure during overvoltage events.
Can P6SMAJ8.0ADFQ-13 be used in bidirectional configurations?
No - it is a unidirectional TVS diode optimized for DC-biased lines. For AC or bipolar signal lines (e.g., RS-485), a bidirectional variant such as P6SMBJ8.0ADFQ-13 must be used, which provides symmetrical clamping above and below ground reference.
How does the D-FLAT package affect thermal performance compared to SMA?
The D-FLAT package reduces junction-to-terminal thermal resistance to 57 °C/W (vs. ~80 °C/W for SMA), enabling faster heat transfer to the PCB copper pad. This allows the device to sustain higher surge repetition rates without exceeding 150 °C junction temperature on properly designed 2 oz copper layouts.
Is P6SMAJ8.0ADFQ-13 compliant with lead-free reflow profiles?
Yes - it features matte tin annealed over copper lead-frame and is qualified for standard Pb-free reflow profiles (JEDEC J-STD-020, peak temperature 260 °C, 60 sec max). Moisture sensitivity level is rated at Level 1, eliminating bake requirements prior to assembly.
