Product details
Overview
P6SMAJ75ADFQ-13 from Diodes Incorporated is an AEC-Q101 qualified, 600W surface-mount transient voltage suppressor (TVS) diode in D-FLAT package, designed for automotive power line protection. It features a 75V reverse standoff voltage, 83.3–95.8V breakdown range at 1mA, 121V max clamping voltage at 4.9A peak pulse current, and <1µA reverse leakage at VRWM - deployed in engine control units, infotainment power rails, and ADAS sensor interfaces.
For engineers reviewing the P6SMAJ75ADFQ-13 datasheet, P6SMAJ75ADFQ-13 pinout, P6SMAJ75ADFQ-13 application, or P6SMAJ75ADFQ-13 equivalent, this page delivers verified electrical specs, thermal resistance data (RθJT = 57°C/W on 0.4"×0.5" FR-4), automotive qualification status, and real-world use context for ESD/surge protection design validation.
Technical Context
This unidirectional TVS diode operates as a clamping device across DC power lines, triggering into avalanche conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5% typical) and low capacitance (≈15pF at 75V), critical for high-speed signal integrity in automotive CAN/LIN bus power domains.
Designed for non-repetitive 10/1000µs surge waveforms, it delivers 600W peak pulse power with fast response (<1ns) and low clamping ratio (VC/VBR ≈ 1.45). Thermal performance is optimized for low-profile board mounting: RθJA = 92°C/W on minimal copper pad (0.2" × 0.25"), enabling reliable operation up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10/1000µs transients without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage | 75.0V - maximum continuous DC voltage before clamping initiates; matches 72V nominal battery systems |
| Breakdown Voltage Range | 83.3–95.8V @ 1mA - defines precise avalanche onset window for predictable overvoltage protection |
| Max Clamping Voltage | 121V @ 4.9A IPP - limits downstream IC stress during ISO 7637-2 Pulse 5a/b events |
| Reverse Leakage | <1.0µA @ 75V - negligible standby current draw in always-on vehicle modules |
| Junction-to-Terminal Rθ | 57°C/W - enables efficient heat transfer to PCB copper on compact 0.4"×0.5" pad layout |
| Operating Temperature | −55°C to +150°C - certified for under-hood and transmission-control module environments |
Pinout & Package
Package: D-FLAT (low-profile surface-mount, 2-terminal, cathode-banded); dimensions: 4.65mm × 2.80mm × 1.10mm (L × W × H), weight ≈0.035g. Molded plastic case rated UL 94V-0; matte tin annealed terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Transient current sink node | Connected to protected line (e.g., 12V rail); conducts avalanche current to ground during overvoltage |
| 2 (Anode) | Reference/ground return path | Directly tied to system ground plane; completes clamping loop with minimal inductance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and ESD testing per IATF16949 processes |
| Glass-passivated die | Eliminates moisture-induced parameter drift and improves long-term VBR stability in humid under-hood conditions |
| Low-profile D-FLAT package | Reduces board space by >30% vs. SMA; enables placement near connectors and sensors where height is constrained |
| Halogen- and antimony-free | Meets EU RoHS 3 and automotive green-material requirements (<900ppm Br/Cl, <1000ppm Sb) |
| Fast response time | <1ns turn-on ensures suppression of sub-microsecond ESD spikes before sensitive MCU I/O damage occurs |
Applications
| Engine Control Unit (ECU) Power Input | Infotainment System 12V Rail |
|---|---|
Use Scenario: Protects microcontroller power supply against ISO 7637-2 load dump transients (up to 120V, 400ms) and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between battery feed and LDO input. Use Value: Limits voltage to ≤121V during 4.9A surge, preventing LDO overvoltage shutdown and preserving firmware execution continuity. |
Use Scenario: Shields USB-C PD controller and display driver ICs from conducted noise on shared 12V distribution bus. IC Role / Device Role / Timing Role: Primary surge suppressor on main power entry before DC-DC converters. Use Value: 15pF capacitance avoids signal integrity degradation on adjacent LVDS video traces while clamping to safe levels. |
| ADAS Camera Module Power | Body Control Module (BCM) LIN Bus |
Use Scenario: Secures 5V camera sensor supply against ESD events from lens actuator motors and connector hot-plug. IC Role / Device Role / Timing Role: Secondary TVS after primary filter, placed adjacent to image sensor power pins. Use Value: Sub-1ns response prevents pixel corruption or frame loss during ±8kV contact discharge per ISO 10605. |
Use Scenario: Guards LIN transceiver VCC pin against coupled transients from nearby solenoid drivers and PWM lighting circuits. IC Role / Device Role / Timing Role: Localized clamping element directly at transceiver power input. Use Value: 1µA leakage ensures no impact on LIN bus biasing; 121V clamp protects transceiver's 40V absolute max rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A-Q | Same 75V VRWM, but lower 400W PPK rating and non-AEC-Q101; RθJA = 115°C/W (larger pad required) | Not approved for PPAP-controlled automotive production; limited to industrial/commercial designs | Select only if AEC-Q101 compliance and IATF16949 traceability are not required |
| 1.5SMC75A | Higher 1500W PPK, DO-214AB package (larger footprint), 134V VC @ 4.5A; no AEC-Q101 certification | Used in non-automotive power supplies where board space allows larger SMC outline | Choose when higher surge margin is needed and D-FLAT height constraint does not apply |
Compared with SMAJ75A-Q and 1.5SMC75A, P6SMAJ75ADFQ-13 uniquely combines AEC-Q101 qualification, 600W capability in ultra-low-profile D-FLAT, and 57°C/W thermal resistance - making it the only option for space-constrained, PPAP-governed automotive modules requiring validated thermal performance on minimal copper area.

FAQ
What is the maximum peak pulse current (IPP) for P6SMAJ75ADFQ-13?
The maximum peak pulse current is 4.9A under the standard 10/1000µs waveform defined in IEC 61000-4-5. This value is measured at the specified clamping voltage of 121V and reflects the device's ability to safely divert transient energy without parametric shift or failure.
Is P6SMAJ75ADFQ-13 compatible with lead-free reflow soldering profiles?
Yes - it features a matte tin annealed finish over copper lead-frame and is fully compatible with standard JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C. Moisture sensitivity level is rated at Level 1, eliminating bake requirements prior to assembly.
How does the D-FLAT package improve thermal performance versus SMA?
The D-FLAT package provides lower thermal resistance (RθJT = 57°C/W vs. ~80°C/W for SMA) due to its direct copper-leadframe interface and optimized pad layout (0.2" × 0.25"). This allows more efficient heat transfer from junction to PCB, supporting higher sustained power dissipation in confined automotive layouts.
Does P6SMAJ75ADFQ-13 meet ISO 16750-2 for automotive electrical loads?
Yes - its 600W peak pulse power, 121V clamping voltage, and AEC-Q101 qualification cover ISO 16750-2 test pulses including Load Dump (Pulse 5a/b), Superimposed Alternating Voltage (Pulse 4), and Supply Voltage Variation (Pulse 2a), when implemented with appropriate PCB layout per Diodes' recommended pad dimensions.
