Product details
Overview
P4SMA7.5AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 7.13 V minimum breakdown voltage (VBR), 6.40 V maximum stand-off voltage (VWM), 11.3 V clamping voltage (VC) at 35.4 A peak pulse current, and 400 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 P4SMA7.5AHE3/61 datasheet, P4SMA7.5AHE3/61 pinout, P4SMA7.5AHE3/61 application, or P4SMA7.5AHE3/61 equivalent, key selection considerations include its AEC-Q101 qualification, unidirectional polarity, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
The P4SMA7.5AHE3/61 operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (7.13–7.88 V at 10 mA). Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns) to transient events such as ESD, inductive switching spikes, and lightning surges.
Thermally, it exhibits 120 °C/W junction-to-ambient thermal resistance (RθJA) on standard 0.2" × 0.2" copper pads and supports repetitive operation at 0.01% duty cycle. The device is rated for 40 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and maintains ≤500 µA reverse leakage at VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Higher VWM (6.0 V), lower VC (11.2 V), same 400 W rating but SMB package (larger footprint) | Requires larger PCB area; better suited for higher-current PCB traces due to lower RθJA (85 °C/W) | Select when thermal margin is critical and board space allows SMB footprint |
| 1.5SMC7.5A | Same VBR/VWM/VC, but SMC package (DO-214AB) with 1500 W rating and higher IPPM (123 A) | Overqualified for 400 W use cases; introduces unnecessary cost and size for typical automotive signal-line protection | Choose only if legacy design uses SMC or future-proofing for higher surge levels is required |
Compared with SMBJ7.0A and 1.5SMC7.5A, the P4SMA7.5AHE3/61 offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and precise 6.40 V stand-off for 5 V–12 V rail protection - making it preferred for space-constrained automotive and industrial modules where qualification and layout efficiency are prioritized.

FAQ
What is the maximum clamping voltage of the P4SMA7.5AHE3/61 under peak pulse conditions?
The P4SMA7.5AHE3/61 has a maximum clamping voltage (VC) of 11.3 V at 35.4 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per JEDEC standards and ensures protected circuits experience no more than 11.3 V during transient events. The clamping performance remains stable across its operating temperature range of -65 °C to +150 °C.
Is the P4SMA7.5AHE3/61 suitable for automotive applications?
Yes, the P4SMA7.5AHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix. It meets stress test requirements including temperature cycling, high-temperature reverse bias, and ESD per JESD47, and is rated for operation up to 150 °C junction temperature - making it appropriate for engine control units, body electronics, and ADAS sensor modules.
What does the "HE3" suffix indicate in P4SMA7.5AHE3/61?
The "HE3" suffix in P4SMA7.5AHE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting JESD201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" parts and confirms compliance with automotive reliability and plating standards required for under-hood deployment.
How does the P4SMA7.5AHE3/61 compare to bidirectional TVS diodes like P4SMA7.5CA?
The P4SMA7.5AHE3/61 is unidirectional and intended for DC line protection where polarity is fixed (e.g., VCC-to-ground), offering tighter VBR tolerance and lower leakage. In contrast, P4SMA7.5CA is bidirectional and used for AC or floating signal lines. They share identical package and power rating but differ in polarity marking, leakage behavior, and applicable surge waveforms - substitution requires circuit-level verification.
What is the thermal resistance of the P4SMA7.5AHE3/61 in standard mounting conditions?
The P4SMA7.5AHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB with no internal copper planes; adding thermal vias or larger copper areas reduces RθJA and improves sustained power handling.
