Product details
Overview
SM6T7V5AHE3_B/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 11.3 V clamping voltage at 53.0 A peak pulse current (IPPM), and 600 W peak pulse power rating per 10/1000 μs waveform. It protects MOSFETs and ICs against inductive switching transients in automotive power electronics.
For engineers reviewing the SM6T7V5AHE3_B/I datasheet, SM6T7V5AHE3_B/I pinout, SM6T7V5AHE3_B/I application, or SM6T7V5AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low-inductance SMB package, and compliance with J-STD-020 MSL level 1 at 260 °C peak reflow.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds its 7.13–7.88 V breakdown range. Its glass-passivated junction ensures stable leakage (<500 μA at 6.40 V) and robust surge handling up to 100 A IFSM (10 ms half-sine).
Designed for surface-mount placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it delivers 600 W peak pulse power dissipation with minimal thermal resistance (RθJA = 100 °C/W) and meets automotive-grade reliability per AEC-Q101 qualification under the HE3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V - defines precise conduction onset threshold for overvoltage clamping |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 11.3 V @ 53.0 A - clamped voltage during 10/1000 μs transient, limiting stress on protected IC |
| PPPM | 600 W - peak transient energy absorption capability under standardized surge waveform |
| IFSM | 100 A - non-repetitive forward surge current rating for inrush or fault conditions |
| TJ max | +150 °C - maximum allowable junction temperature enabling operation in under-hood automotive environments |
| MSL Level | Level 1 (J-STD-020) - supports standard SMT reflow without dry-pack or baking requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same SMB package, 7.5 V nominal VWM, 12.0 V VC @ 42 A, 400 W PPPM | Lower peak power rating limits use in high-energy automotive load dump scenarios | Select SMAJ7.5A only where system-level surge energy is confirmed ≤400 W |
| 1.5SMC7.5A | Higher-power SMC package (7.5 mm × 6.2 mm), same VBR range, 12.5 V VC @ 48 A, 1500 W PPPM | Larger footprint incompatible with space-constrained SMB layouts; suited for industrial mains inputs | Choose 1.5SMC7.5A when board area allows and >600 W surge margin is required |
Compared with SMAJ7.5A and 1.5SMC7.5A, SM6T7V5AHE3_B/I offers optimal balance of AEC-Q101 qualification, 600 W capability, and SMB footprint-making it preferred for automotive and dense consumer power designs where reliability and space are co-constrained.

FAQ
What is the exact breakdown voltage range for SM6T7V5AHE3_B/I?
The SM6T7V5AHE3_B/I has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current (IT), measured per JEDEC standards. This tight tolerance ensures predictable clamping behavior in 5 V and 6.4 V system rails. The value is confirmed in Vishay's official datasheet revision 09-Jan-2024, document number 88385.
Is SM6T7V5AHE3_B/I qualified for automotive applications?
Yes, SM6T7V5AHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" suffix in its ordering code. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge robustness per automotive reliability standards. This makes SM6T7V5AHE3_B/I suitable for under-hood and body-control module deployments.
What does the "_B/I" suffix mean in SM6T7V5AHE3_B/I?
The "_B/I" suffix denotes packaging configuration: "B" indicates tape-and-reel revision level (e.g., revision B of the reel specification), and "I" specifies 13-inch diameter plastic tape and reel with 3200 units per reel. This format aligns with Vishay's standard ordering nomenclature for high-volume SMT assembly.
Can SM6T7V5AHE3_B/I be used in bidirectional configurations?
No, SM6T7V5AHE3_B/I is unidirectional only. Bidirectional variants require the "CA" suffix (e.g., SM6T7V5CA). Using SM6T7V5AHE3_B/I in reverse-biased AC applications would result in forward conduction and failure. Always verify polarity marking-the cathode band must face the protected line.
What is the maximum clamping voltage of SM6T7V5AHE3_B/I under surge conditions?
The maximum clamping voltage (VC) of SM6T7V5AHE3_B/I is 11.3 V at 53.0 A peak pulse current (IPPM) under the industry-standard 10/1000 μs waveform. This value is measured per Figure 1 in the datasheet and defines the upper voltage limit imposed on protected circuitry during transient events.
