Product details
Overview
SM6T7V5AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 7.13–7.88 V breakdown voltage at 10 mA, and 11.3 V maximum clamping voltage at 53.0 A peak pulse current. It protects MOSFETs and sensor signal lines in automotive ECUs against inductive switching transients.
For engineers reviewing the SM6T7V5AHE3/5B datasheet, SM6T7V5AHE3/5B pinout, SM6T7V5AHE3/5B application, or SM6T7V5AHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, clamping performance under standardized waveforms, and direct alternative part comparisons for ESD and surge protection design-in.
Technical Context
The SM6T7V5AHE3/5B operates as a unidirectional avalanche clamp with glass-passivated junction, optimized for low-inductance transient suppression. Its 100 °C/W junction-to-ambient thermal resistance and 20 °C/W junction-to-lead resistance support reliable operation up to 150 °C junction temperature under pulsed stress.
Designed for surface-mount automated placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (260 °C peak reflow) and is qualified to AEC-Q101 for automotive use - confirmed by HE3 suffix and Vishay's revision-controlled documentation (Doc #88385, Rev 09-Jan-2024).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.13 V / 7.88 V at 10 mA - defines precise avalanche initiation threshold for repeatable clamping onset |

| VC @ IPPM | 11.3 V at 53.0 A (10/1000 μs) - actual worst-case clamping voltage seen by protected IC during surge |
| PPPM | 600 W - peak transient power handling capability under standardized lightning/surge waveform |
| TJ max | +150 °C - maximum allowable junction temperature enabling under-hood automotive deployment |
| RθJA | 100 °C/W - thermal resistance used to calculate junction temperature rise under DC bias or repetitive pulses |
Pinout & Package

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, 7.5 V nominal VBR, but lower PPPM = 400 W and higher VC = 12.0 V at 33.3 A | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification or 600 W surge margin |
| 1.5SMC7.5A | Higher-power SMC package (PPPM = 1500 W), same VBR range, but 2.5× larger footprint and 3× higher RθJA | Used where board space allows and higher single-pulse energy must be absorbed | Choose only if system-level testing confirms 1500 W requirement; otherwise SM6T7V5AHE3/5B offers better density and thermal efficiency |
Compared with SMAJ7.5A and 1.5SMC7.5A, SM6T7V5AHE3/5B delivers optimal balance of AEC-Q101 compliance, 600 W surge capacity, compact SMB footprint, and 11.3 V clamping - making it preferred for space-constrained automotive and industrial signal-line protection where reliability and repeatability are critical.

FAQ
What is the clamping voltage of SM6T7V5AHE3/5B under a 10/1000 μs surge?
The SM6T7V5AHE3/5B has a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 53.0 A under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay Document #88385 and represents the highest voltage the protected circuit will experience during such a transient. The SM6T7V5AHE3/5B maintains this clamping performance consistently due to its glass-passivated junction and SMB package geometry.
Is SM6T7V5AHE3/5B qualified for automotive applications?
Yes, SM6T7V5AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and explicit statement in Vishay's SM6T datasheet (Rev 09-Jan-2024, Doc #88385). It is rated for operating junction temperatures from –65 °C to +150 °C and meets MSL Level 1 reflow requirements - making it suitable for under-hood and body-control module deployments. The SM6T7V5AHE3/5B undergoes stress testing per AEC-Q101 standards including HTGB, HTRB, and TCT.
What does the "5B" in SM6T7V5AHE3/5B indicate?
The "5B" suffix in SM6T7V5AHE3/5B specifies the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This differs from "52", which denotes 7-inch tape-and-reel (750 units). Both share identical electrical and thermal specifications; the SM6T7V5AHE3/5B variant is optimized for high-volume SMT assembly lines requiring extended reel length and reduced changeover frequency.
How does SM6T7V5AHE3/5B compare to bidirectional TVS diodes like SM6T7V5CA?
The SM6T7V5AHE3/5B is unidirectional and designed for DC-biased circuits where transients occur only in one polarity - e.g., protecting a 5 V rail referenced to ground. In contrast, SM6T7V5CA is bidirectional and handles symmetrical AC or floating signals. The SM6T7V5AHE3/5B offers tighter VBR tolerance (7.13–7.88 V) and lower VC than its bidirectional counterpart, but cannot suppress negative-going transients on grounded lines without additional circuitry.
What is the maximum reverse leakage current for SM6T7V5AHE3/5B at its stand-off voltage?
At its maximum stand-off voltage (VWM) of 6.40 V, the SM6T7V5AHE3/5B exhibits a maximum reverse leakage current (ID) of 500 μA at 25 °C, as specified in Table "ELECTRICAL CHARACTERISTICS" of Vishay Doc #88385. This low leakage ensures minimal power loss and signal interference in always-on sensor or communication interfaces, and remains within acceptable limits even at elevated ambient temperatures due to the device's thermal design.
