Product details
Overview
P6SMAJ7.5ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in the D-FLAT package, designed for automotive power line protection. It features a 7.5V reverse standoff voltage, 8.33–9.58V breakdown voltage at 1.0mA test current, 12.9V max clamping voltage at 46.5A peak pulse current, and is optimized for fast response to ESD and surge events in 12V battery systems.
For engineers reviewing the P6SMAJ7.5ADFQ-13 datasheet, P6SMAJ7.5ADFQ-13 pinout, P6SMAJ7.5ADFQ-13 application, or P6SMAJ7.5ADFQ-13 equivalent, this device is selected for robust overvoltage protection in automotive infotainment power rails, body control modules, and CAN transceiver I/O lines where low clamping voltage, high surge capability, and AEC-Q101 compliance are mandatory.
Technical Context
This TVS diode operates as a unidirectional, cathode-anode configured clamp with glass-passivated junction construction. Its 12.9V clamping voltage at 46.5A (10/1000µs waveform) ensures reliable suppression of ISO 7637-2 Pulse 1, 2a, and 5a transients in automotive 12V systems.
The D-FLAT package delivers low thermal resistance (RθJT = 57°C/W on 0.4"×0.5" PCB pad), enabling effective power dissipation during 600W non-repetitive surges. Its 100µA max reverse leakage at 7.5V VRWM supports low standby current in always-on vehicle subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - withstands ISO 7637-2 Pulse 5a surges without failure |
| Reverse Standoff Voltage | 7.5V - sets minimum operating voltage before clamping activates in 12V automotive systems |
| Breakdown Voltage Range | 8.33–9.58V @ 1.0mA - ensures consistent turn-on across temperature and process variation |
| Max Clamping Voltage | 12.9V @ 46.5A - limits downstream IC stress below 13.5V during worst-case transients |
| Peak Pulse Current | 46.5A (10/1000µs) - meets automotive surge immunity requirements for Class III loads |
| Reverse Leakage | 100µA @ 7.5V - minimizes quiescent current drain in battery-sensitive modules |
| Thermal Resistance (Junction-to-Terminal) | 57°C/W - enables stable operation under sustained surge duty with minimal board copper |
Pinout & Package
Package: D-FLAT (2-pin, surface-mount, cathode-banded). Dimensions: 4.65mm × 2.80mm × 1.10mm (L × W × H), with 0.2" × 0.25" recommended copper pad per JEDEC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to protected line (e.g., VBAT or signal rail); clamps when voltage exceeds breakdown |
| 2 (Non-Banded End) | Anode | Connected to ground reference; completes conduction path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock per JESD22 |
| Glass-passivated die | Enhances long-term reliability and moisture resistance in under-hood environments |
| Low-profile D-FLAT package | Reduces board space by >40% vs. SMA while maintaining 600W surge rating |
| Lead-free & halogen-free | Complies with RoHS 3 and automotive green standards (<900ppm Br/Cl, <1000ppm Sb) |
| Fast response time | Sub-nanosecond turn-on ensures clamping before sensitive ICs experience overvoltage damage |
Applications
| Infotainment Power Rail Protection | Body Control Module (BCM) Input Protection |
|---|---|
Use Scenario: Protecting 12V supply inputs to head unit processors and display drivers against load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between fuse output and DC-DC input, activated within 1ns upon overvoltage detection. Use Value: Limits voltage to ≤12.9V during 46.5A surges, preventing latch-up or permanent damage to 13.5V-rated PMICs. | Use Scenario: Safeguarding microcontroller GPIO and LIN bus pins in door module ECUs exposed to wiring harness ESD. IC Role / Device Role / Timing Role: Cathode-to-rail placement for bidirectional protection when paired with series resistor; clamps negative transients via forward conduction. Use Value: 100µA leakage preserves sleep-mode current budget; 12.9V clamping protects 5V logic interfaces referenced to 12V battery. |
| CAN Transceiver I/O Protection | Start-Stop System Battery Monitoring |
Use Scenario: Shielding CANH/CANL differential pair inputs from coupled transients in chassis-grounded vehicle networks. IC Role / Device Role / Timing Role: Dual-device configuration (one per line) with cathodes tied to VCC, providing common-mode surge suppression. Use Value: 8.33–9.58V breakdown aligns with CAN transceiver common-mode range, avoiding false triggering during normal operation. | Use Scenario: Protecting analog front-end inputs of battery sensor ICs measuring 12V system voltage during engine cranking. IC Role / Device Role / Timing Role: Placed upstream of precision voltage divider; clamps spikes without affecting 12-bit ADC accuracy. Use Value: 12.9V clamping ensures sensor input stays within ±0.5% full-scale error window during 600W surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-Q | Same electrical specs but not AEC-Q101 qualified; RθJA = 115°C/W (vs. 92°C/W) | Limited to industrial/commercial use; lacks PPAP documentation and IATF16949 traceability | Select only for non-automotive designs where cost sensitivity outweighs qualification requirements |
| 1.5SMC7.5A | Higher 1500W rating but larger SMC package (7.1mm × 6.2mm); VF = 3.5V @ 35A | Requires more PCB area; better suited for 24V commercial systems than compact 12V automotive layouts | Choose when higher surge margin is needed and board space permits larger footprint |
Compared with SMAJ7.5A-Q and 1.5SMC7.5A, P6SMAJ7.5ADFQ-13 uniquely balances AEC-Q101 compliance, D-FLAT space efficiency, and 600W surge capability-making it optimal for space-constrained, safety-critical automotive modules requiring full PPAP support.

FAQ
What is the maximum operating temperature for P6SMAJ7.5ADFQ-13?
The device operates from –55°C to +150°C junction temperature. Its thermal resistance (RθJT = 57°C/W) allows sustained operation at +125°C ambient when mounted on a 0.4" × 0.5" copper pad, making it suitable for under-dash and engine bay locations.
Is P6SMAJ7.5ADFQ-13 compatible with lead-free reflow soldering?
Yes-it features matte tin annealed over copper lead-frame and is rated for standard Pb-free reflow profiles (peak 260°C, 20–40 sec), compliant with J-STD-020 moisture sensitivity Level 1 and RoHS 3 requirements.
How does its clamping performance compare to older SMAJ series devices?
P6SMAJ7.5ADFQ-13 achieves 12.9V clamping at 46.5A, which is 0.4V lower than SMAJ7.5A's 13.3V spec at same current-due to improved die design and tighter parameter distribution, directly enhancing protection margin for 13.5V-rated downstream ICs.
Can this TVS be used in bidirectional configurations?
No-it is unidirectional. For bidirectional protection, two devices must be used in series opposition (anode-to-anode), or a dedicated bidirectional part like P6SMBJ7.5ADFQ-13 should be selected to avoid forward conduction issues on negative transients.
