Product details
Overview
P6SMB7.5AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V maximum clamping voltage (VC) at 53.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB7.5AHE3_A/I datasheet, P6SMB7.5AHE3_A/I pinout, P6SMB7.5AHE3_A/I application, or P6SMB7.5AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (7.13–7.88 V). Its glass-passivated junction ensures stable leakage performance (<500 μA at VWM) and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device is rated for 600 W peak pulse power under 10/1000 μs waveform with 0.01% duty cycle, and supports 100 A non-repetitive forward surge current (8.3 ms half-sine). Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), requiring appropriate PCB copper area for thermal management in high-reliability applications.
Key Specifications

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; VC = 12.0 V at 33.3 A | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and higher surge margin |
| 1.5SMC7.5A | Higher 1500 W PPPM, larger SMC (DO-214AB) package; VC = 12.9 V at 116 A | Requires larger PCB area; better suited for primary-side or high-power industrial rails | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger footprint |
Compared with SMAJ7.5A and 1.5SMC7.5A, P6SMB7.5AHE3_A/I delivers optimal balance of AEC-Q101 compliance, 600 W surge capacity, and SMB footprint - making it preferred for space-constrained automotive modules and industrial controllers where qualification and reliability are mandatory.

FAQ
What is the breakdown voltage range for P6SMB7.5AHE3_A/I?
The P6SMB7.5AHE3_A/I has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design for 5 V–12 V systems where P6SMB7.5AHE3_A/I is commonly deployed.
Is P6SMB7.5AHE3_A/I AEC-Q101 qualified?
Yes, P6SMB7.5AHE3_A/I is AEC-Q101 qualified - confirmed by Vishay's ordering code suffix "HE3" and documentation revision 09-Jan-2024 (Document Number: 88370). The "_A/I" denotes 13-inch tape-and-reel packaging, and qualification covers temperature cycling, highly accelerated stress testing (HAST), and mechanical shock per automotive reliability standards.
What is the maximum clamping voltage of P6SMB7.5AHE3_A/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB7.5AHE3_A/I is 11.3 V at 53.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during transient events and is critical for ensuring downstream components like microcontrollers or LDOs remain within safe operating limits when P6SMB7.5AHE3_A/I activates.
Can P6SMB7.5AHE3_A/I be used in bidirectional configurations?
No, P6SMB7.5AHE3_A/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies part numbers ending in "CA" (e.g., P6SMB7.5CA). Using P6SMB7.5AHE3_A/I in reverse-biased signal paths would result in forward conduction and failure to suppress negative-going transients.
What PCB layout guidance applies to P6SMB7.5AHE3_A/I for optimal thermal and electrical performance?
Vishay specifies mounting P6SMB7.5AHE3_A/I on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal resistance (RθJA = 100 °C/W). Traces to ground should be short and wide to minimize inductance, and the cathode pad must maintain clear isolation from adjacent nets to prevent arcing during clamping events involving P6SMB7.5AHE3_A/I.
