Product details
Overview
SM6T7V5CAHE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V maximum clamping voltage (VC) at 53.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SM6T7V5CAHE3_A/I datasheet, SM6T7V5CAHE3_A/I pinout, SM6T7V5CAHE3_A/I application, or SM6T7V5CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.59), TJ = –65 °C to +150 °C operation, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
The SM6T7V5CAHE3_A/I is a glass-passivated, bidirectional TVS diode optimized for fast response to transient overvoltages induced by inductive switching or ESD events. Its symmetrical junction structure enables identical clamping behavior in both polarities, with VBR tested at 10 mA and VC specified at 53.0 A using standardized 10/1000 μs waveform.
It operates within –65 °C to +150 °C junction temperature range, exhibits 100 °C/W typical junction-to-ambient thermal resistance, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. The device is AEC-Q101 qualified and RoHS-compliant, with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5CA | Same SMB package; 7.5 V nominal VWM, 12.0 V VC @ 42.5 A; 400 W PPPM | Lower power rating reduces margin for high-energy transients like ISO 7637-2 Pulse 5a | Select when cost sensitivity outweighs need for full 600 W surge headroom |
| SMCJ7.5CA | SMC (DO-214AB) package; same VBR/VC; 1500 W PPPM; larger footprint | Higher power capability suits 48 V systems but requires PCB area increase and layout revision | Choose for heavy-duty industrial drives where 600 W is insufficient and space allows larger package |
Compared with SMAJ7.5CA and SMCJ7.5CA, the SM6T7V5CAHE3_A/I delivers optimal balance of AEC-Q101 qualification, 600 W surge capacity, and SMB footprint - making it preferred for space-constrained automotive and industrial designs requiring validated reliability without board redesign.

FAQ
What is the polarity configuration of SM6T7V5CAHE3_A/I?
The SM6T7V5CAHE3_A/I is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity marking on the SMB package. Its "CA" suffix explicitly denotes bidirectional functionality, and electrical characteristics apply identically in either direction per Vishay documentation.
Is SM6T7V5CAHE3_A/I qualified for automotive use?
Yes, SM6T7V5CAHE3_A/I is AEC-Q101 qualified, as confirmed by its "HE3" suffix and explicit listing in Vishay's AEC-Q101 qualified product table. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum clamping voltage of SM6T7V5CAHE3_A/I under surge conditions?
The maximum clamping voltage (VC) of SM6T7V5CAHE3_A/I is 11.3 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 53.0 A, measured per Figure 1 and Table on page 2 of Vishay document 88385. This value ensures safe operation for 5 V logic and interface ICs during transient events.
Does SM6T7V5CAHE3_A/I require special PCB layout considerations?
Yes - Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Deviating from this pad size reduces thermal dissipation and degrades surge capability. The SMB footprint also requires adherence to IPC-7351B standard dimensions for reliable reflow soldering.
How does the "HE3" suffix in SM6T7V5CAHE3_A/I affect its specifications?
"HE3" indicates RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It does not alter electrical parameters versus non-HE3 variants but adds automotive-grade reliability validation and lead finish requirements essential for high-reliability production.
