Product details
Overview
P6SMB7.5H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 6.75–8.25 V, stand-off voltage of 6.05 V, and clamping voltage of 11.7 V at 53 A peak pulse current. It protects automotive and industrial electronics against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB7.5H datasheet, P6SMB7.5H pinout, P6SMB7.5H application, or P6SMB7.5H equivalent, key selection criteria include its 600W peak pulse power rating, 10 mA test current, <1 µA leakage at 6.05 V, AEC-Q101 qualification, and DO-214AA (SMB) package compatibility with automated SMT assembly.
Technical Context
The P6SMB7.5H operates as a unidirectional avalanche-clamping TVS diode optimized for fast transient suppression in 12 V automotive and industrial power rails. Its glass-passivated junction ensures stable breakdown behavior, while its low 10.8–11.7 V clamping voltage limits stress on downstream ICs during 10/1000 µs surges.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, enabling reliable operation up to TJ = 150 °C. It meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, supporting lead-free reflow without popcorn failure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.75 V / 8.25 V - Ensures consistent avalanche initiation across production units at 10 mA test current |
| VWM | 6.05 V - Maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 53 A - Peak surge current it safely clamps under 10/1000 µs waveform without degradation |
| VC@IPPM | 11.7 V - Clamped voltage seen by protected circuit during full-rated surge, limiting IC stress |
| PPPSM | 600 W - Non-repetitive peak pulse power handling per IEC 61000-4-5 and ISO 7637-2 compliance |
| TJ max | +150 °C - Junction temperature limit enabling use in under-hood automotive environments |
| Leakage @ VWM | <500 µA - Low standby current preserves battery life in always-on vehicle modules |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, single-diode configuration with cathode band marking. Dimensions conform to JEDEC DO-214AA standard; terminals are matte tin-plated for J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / surge return path | Connected to ground or low-impedance return plane; carries full surge current during clamping |
| Cathode | Protected line connection / high-side clamp node | Connected to the line being protected (e.g., 12 V rail); reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass passivated junction | Provides stable VBR tolerance and long-term parameter drift <0.5% over lifetime at rated conditions |
| Fast response time | Typically <1.0 ps - Enables clamping before transient energy couples into sensitive analog or digital circuitry |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling) waveforms |
| Moisture sensitivity level 1 | Zero bake requirement prior to reflow - supports direct placement and standard Pb-free reflow profiles |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V battery-supplied ECUs exposed to load dump and alternator ripple. IC Role / Device Role: Unidirectional TVS placed between power rail and ground to clamp transients before they reach PMICs or microcontrollers. Use Value: Limits voltage to ≤11.7 V during 53 A surges, preventing latch-up or gate oxide damage in 5 V/3.3 V logic supplies derived from the rail. | Use Scenario: 4–20 mA current-loop sensors connected to PLC analog inputs in factory automation. IC Role / Device Role: TVS mounted at sensor terminal block to absorb EFT bursts and cable-coupled surges before reaching op-amp front-end. Use Value: Sub-µA leakage at 6.05 V avoids signal offset errors; 600 W rating handles repeated 1 kV/50 Ω EFT events per IEC 61000-4-4. |
| LED Lighting Driver Input Protection | Automotive CAN Transceiver Bus Line Protection |
Use Scenario: Constant-current LED drivers powered from vehicle battery with PWM dimming control. IC Role / Device Role: Input-side TVS on driver VIN pin to suppress switching noise and load dump spikes. Use Value: 6.05 V VWM allows safe operation above nominal 5.5 V logic supply while clamping to 11.7 V - compatible with 12 V input stage MOSFETs. | Use Scenario: CAN FD transceivers (e.g., TCAN1042) in body control modules subject to battery disconnect transients. IC Role / Device Role: Bidirectional protection not applicable - P6SMB7.5H used on VCC supply rail only, not data lines. Use Value: AEC-Q101 qualification and 150 °C TJ rating ensure robustness in hot under-dash locations where CAN nodes operate continuously. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5A | Same DO-214AA package; 7.5 V nominal VBR, but tighter 6.8–7.9 V min/max range and lower 11.3 V VC at 55 A | Lower clamping voltage suits margin-constrained 5 V systems; identical AEC-Q101 qualification | Select SMBJ7.5A when clamping voltage headroom is <0.4 V below system absolute maximum rating |
| 1.5SMC7.5A | Higher 1500 W PPPSM; larger DO-214AB (SMC) package; VBR 6.8–7.9 V; VC = 12.9 V at 116 A | Used where higher surge repetition rate or longer duration pulses occur; not drop-in due to footprint mismatch | Choose 1.5SMC7.5A only if PCB layout allows SMC pad geometry and thermal mass supports higher energy dissipation |
Compared with SMBJ7.5A and 1.5SMC7.5A, the P6SMB7.5H offers optimal balance of compact SMB footprint, AEC-Q101 compliance, and 600 W capability - making it preferred for space-constrained automotive modules where 11.7 V clamping is acceptable and board area is premium.

FAQ
What is the maximum clamping voltage of the P6SMB7.5H under rated surge conditions?
The P6SMB7.5H has a maximum clamping voltage (VC) of 11.7 V at 53 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is guaranteed across temperature and process variation per the datasheet's Electrical Specifications table and defines the upper voltage limit imposed on protected circuits during transient events.
Is the P6SMB7.5H suitable for bidirectional transient protection?
No, the P6SMB7.5H is a unidirectional TVS diode intended for DC power rail protection only. For bidirectional applications such as AC lines or data bus protection, TSC offers the P6SMB7.5AH variant (with "AH" suffix), which features symmetrical breakdown in both directions and different marking code (KGJ).
Does the P6SMB7.5H meet automotive reliability standards?
Yes, the P6SMB7.5H is AEC-Q101 qualified and tested per the full stress test schedule including HTGB, HTRB, temperature cycling, and mechanical shock. It also complies with JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 - confirming suitability for automotive under-hood and cabin applications.
What is the leakage current specification for the P6SMB7.5H at its stand-off voltage?
At its rated stand-off voltage (VWM) of 6.05 V, the P6SMB7.5H exhibits a maximum reverse leakage current (ID) of 500 µA at TA = 25 °C. This low leakage supports energy-sensitive designs such as always-on vehicle modules where quiescent current must remain minimal.
Can the P6SMB7.5H be used in place of the P6SMB7.5AH?
No - the P6SMB7.5H and P6SMB7.5AH are electrically distinct: the former is unidirectional with cathode-band polarity, while the latter is bidirectional and lacks polarity marking. Substituting one for the other without circuit review risks improper clamping or open-circuit failure during reverse transients.
