Product details
Overview
P6SMB7.5AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 7.13 V minimum breakdown voltage (VBR), 6.40 V maximum stand-off voltage (VWM), and clamps transients to 11.3 V at 53.1 A peak pulse current (IPPM) under 10/1000 μs waveform - ideal for safeguarding power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6SMB7.5AHE3_A/H datasheet, P6SMB7.5AHE3_A/H pinout, P6SMB7.5AHE3_A/H application, or P6SMB7.5AHE3_A/H equivalent, this device delivers AEC-Q101 qualification, 600 W peak pulse power capability, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial designs requiring validated transient immunity without layout redesign.
Technical Context
The P6SMB7.5AHE3_A/H operates as a unidirectional clamping TVS diode with glass-passivated junction and cathode-band polarity marking. Its 10/1000 μs waveform response achieves 11.3 V clamping voltage at 53.1 A, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, enabling effective surge energy dissipation on standard 0.2" × 0.2" copper pads.
It meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C), supports 100 A non-repetitive forward surge current (IFSM), and exhibits 0.061 %/°C temperature coefficient of VBR, ensuring stable clamping performance across -65 °C to +150 °C operating junction range.
Key Specifications

|---|---|
|
Use Scenario: Protecting 5 V supply lines in engine control units (ECUs) against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between VIN and GND, triggered only during positive overvoltage events. Use Value: Limits transient voltage to 11.3 V, preventing damage to microcontrollers and CAN transceivers rated for ≤ 16 V absolute maximum. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in programmable logic controllers (PLCs) exposed to field wiring surges. IC Role / Device Role / Timing Role: Standoff-mode protector on signal path, absorbing fast-rising ESD and lightning-induced spikes before reaching precision DACs or op-amps. Use Value: 53.1 A IPPM capacity handles 1 kV/500 Ω IEC 61000-4-5 surges while maintaining < 1 μA leakage at 6.4 V. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Protection |
|
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters where 5 V rail must survive accidental 12 V misconnection or flyback overshoot. IC Role / Device Role / Timing Role: Fast-response clamping diode placed directly at DC-DC converter input, activated within picoseconds of overvoltage onset. Use Value: 11.3 V clamping voltage ensures downstream buck controller remains within its 16 V absolute max rating during fault conditions. |
Use Scenario: Primary protection for Ethernet PHY power pins (e.g., 3.3 V bias rails) in network switches subjected to induced surges from nearby AC mains or PoE transients. IC Role / Device Role / Timing Role: Low-capacitance unidirectional suppressor integrated into front-end filter stage, minimizing signal integrity impact. Use Value: 0.061 %/°C VBR tempco ensures consistent clamping threshold across -40 °C to +85 °C telecom operating range. |
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 | Same SMB package, but lower 400 W PPPM, higher 12.0 V VC at 32.3 A IPPM | Limited to less severe surge environments (IEC 61000-4-5 Level 2–3); not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 600 W surge margin requirements |
| 1.5SMC7.5A | Higher-power SMC package (1500 W), larger footprint (0.285" × 0.235"), same VWM/VBR specs | Used where PCB space permits and higher single-event energy absorption is required (e.g., AC input stages) | Choose when system-level surge testing exceeds 600 W or when thermal derating demands lower RθJA |
Compared with SMAJ7.5A and 1.5SMC7.5A, the P6SMB7.5AHE3_A/H uniquely balances AEC-Q101 compliance, 600 W capability, and SMB footprint - making it the optimal choice for space-constrained automotive and industrial modules needing production-grade transient immunity without board redesign.

FAQ
What is the clamping voltage of P6SMB7.5AHE3_A/H at its rated peak pulse current?
The P6SMB7.5AHE3_A/H has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream ICs. The P6SMB7.5AHE3_A/H maintains this clamping performance across its specified operating temperature range and is validated for repetitive surge duty cycles up to 0.01 %.
Is P6SMB7.5AHE3_A/H qualified for automotive applications?
Yes, P6SMB7.5AHE3_A/H is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's P6SMB datasheet (Document Number 88370, Revision 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, making the P6SMB7.5AHE3_A/H suitable for under-hood and cabin electronics in passenger vehicles and commercial vehicles.
What does the "HE3" and "_A/H" suffix denote in P6SMB7.5AHE3_A/H?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification, while "_A/H" specifies packaging: "A" denotes the revision code and "H" identifies the 7" diameter plastic tape-and-reel delivery format (750 units per reel). This ordering code aligns with Vishay's documented format in the P6SMB datasheet Table "ORDERING INFORMATION", confirming full traceability and manufacturing compliance.
How does P6SMB7.5AHE3_A/H compare to bidirectional variants like P6SMB7.5CA?
The P6SMB7.5AHE3_A/H is unidirectional and features a cathode band for polarity identification, whereas P6SMB7.5CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P6SMB7.5AHE3_A/H offers tighter VBR tolerance (7.13–7.88 V) and lower leakage (< 500 μA at VWM) than its bidirectional counterpart, making it preferred for DC rail protection where polarity is fixed and leakage must be minimized.
What is the thermal resistance of P6SMB7.5AHE3_A/H, and how does it affect PCB layout?
The P6SMB7.5AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W, measured on 0.2" × 0.2" copper pads per datasheet condition. To maintain safe junction temperatures during repetitive surges, PCB layout must use minimum recommended pad dimensions (0.086" × 0.060") and avoid excessive trace length or isolation - the P6SMB7.5AHE3_A/H relies on lead conduction for primary heat transfer.
