Overview
P6SMB75AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 75 V standoff voltage (VWM), 78.8 V maximum breakdown voltage (VBR), 103 V clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6SMB75AHE3_A/H datasheet, P6SMB75AHE3_A/H pinout, P6SMB75AHE3_A/H application, or P6SMB75AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMB (DO-214AA) package dimensions, thermal resistance data, and real-world protection use cases - all confirmed from Vishay's official P6SMB Series specification document (88370, Rev. 09-Jan-2024).
Technical Context
The P6SMB75AHE3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (71.3–78.8 V at 1 mA). Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced transients, and inductive switching spikes on DC rails and analog signal paths.
Designed for surface-mount assembly on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C) and is qualified to AEC-Q101 for automotive applications - confirmed by the "HE3" suffix and revision code "A/H" in the ordering nomenclature.

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-E3/57T | Same SMB package, 75 V VWM, but lower PPPM (400 W) and higher VC (121 V at 3.3 A); no AEC-Q101 qualification. | Limited to commercial-grade consumer and office equipment; not suitable for automotive or harsh industrial use. | Select when cost sensitivity outweighs automotive qualification and higher surge margin requirements. |
| 1.5SMC75A | Same 75 V rating but in larger SMC (DO-214AB) package; 600 W rating retained, but RθJA = 40 °C/W improves thermal performance. | Better suited for high-reliability power supply rails where board space allows larger footprint and enhanced heat dissipation. | Choose when thermal management is critical and PCB layout permits 2.54 mm longer body and wider pad spacing. |

FAQ
What is the clamping voltage of P6SMB75AHE3_A/H at its rated peak pulse current?
The P6SMB75AHE3_A/H has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value is specified in Vishay's official datasheet (Document Number 88370, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB75AHE3_A/H maintains this clamping performance across its qualified temperature range (−65 °C to +150 °C).
Is P6SMB75AHE3_A/H qualified for automotive applications?
Yes, P6SMB75AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and revision code "A/H" in its ordering nomenclature. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 requirements. This qualification makes P6SMB75AHE3_A/H suitable for under-hood and cabin electronics such as engine control units, ADAS sensors, and body control modules.
What is the standoff voltage (VWM) of P6SMB75AHE3_A/H, and how does it relate to system design?
The standoff voltage (VWM) of P6SMB75AHE3_A/H is 64.1 V - the maximum DC or continuous reverse voltage the device can withstand without entering avalanche conduction. In system design, VWM must exceed the normal operating voltage of the protected line (e.g., 48 V nominal bus) with sufficient margin to avoid leakage or premature clamping. For a 60 V DC rail, P6SMB75AHE3_A/H provides 4.1 V headroom, ensuring stable operation under ripple and tolerance variation.
Does P6SMB75AHE3_A/H have a bidirectional variant, and how does it differ?
No, P6SMB75AHE3_A/H is strictly unidirectional, indicated by the "A" suffix (versus "CA" for bidirectional). Its cathode band marks the clamping terminal, and it conducts only in reverse bias. A bidirectional equivalent would be P6SMB75CAHE3_A/H, which clamps symmetrically in both directions with identical VWM (64.1 V) and VC (103 V) values - used where AC-coupled or floating signal lines require protection without polarity constraints.
What is the thermal resistance and maximum junction temperature of P6SMB75AHE3_A/H?
P6SMB75AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, and a maximum junction temperature (TJ max.) of +150 °C. These values define its power derating curve: at 75 °C ambient, its usable power drops to ~2.5 W (50 % of 5.0 W rated PD), ensuring long-term reliability in enclosed or high-temperature environments where P6SMB75AHE3_A/H is deployed.
