Product details
Overview
SM6T7V5AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 7.13 V minimum breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 11.3 V maximum clamping voltage at 53.0 A peak pulse current (IPPM), and 600 W peak pulse power rating per 10/1000 μs waveform - deployed for overvoltage protection of MOSFETs and sensor signal lines in automotive ECUs.
For engineers reviewing the SM6T7V5AHM3/H datasheet, SM6T7V5AHM3/H pinout, SM6T7V5AHM3/H application, or SM6T7V5AHM3/H equivalent, key selection criteria include verified clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, halogen-free RoHS compliance, SMB package thermal resistance (RθJL = 20 °C/W), and unidirectional polarity with cathode band marking.
Technical Context
The SM6T7V5AHM3/H operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its 7.13–7.88 V breakdown range at 10 mA test current. Its glass-passivated junction ensures stable leakage (<500 μA at 6.40 V) and low inductance for fast response to ESD and load-switching transients.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads, it delivers 600 W peak pulse power dissipation with derating above 25 °C ambient, and supports operating junction temperatures from –65 °C to +150 °C - meeting MSL Level 1 reflow requirements up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.13 V / 7.88 V at 10 mA - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 6.40 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 11.3 V at 53.0 A (10/1000 μs) - clamping voltage limiting protected circuit stress during surge events |
| PPPM | 600 W - peak transient power handling capability under standardized lightning-surge waveform |
| IFSM | 100 A - surge current rating for 10 ms half-sine wave, critical for inductive switch-off protection |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supporting power dissipation without heatsink |
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 VWM (6.4 V), but lower PPPM (400 W); SMA package (higher RθJA = 150 °C/W) | Limited to lower-energy transients; unsuitable for automotive load-dump per ISO 7637-2 Pulse 5a | Select SMAJ7.5A only for cost-sensitive consumer applications with <400 W surge exposure |
| SMCJ7.0A | Higher PPPM (1500 W), same SMB footprint; VBR min = 7.78 V (tighter 5% tolerance vs. SM6T7V5AHM3/H's 10%) | Better suited for industrial 24 V systems requiring higher clamping margin and tighter VBR consistency | Choose SMCJ7.0A when design requires >1 kW surge headroom and tighter breakdown distribution |
Compared with SMAJ7.5A and SMCJ7.0A, the SM6T7V5AHM3/H provides optimal balance of AEC-Q101 qualification, 600 W capability, and halogen-free compliance in SMB - making it the preferred choice for automotive and industrial designs requiring validated reliability without over-spec'ing power rating.

FAQ
What is the exact breakdown voltage range for SM6T7V5AHM3/H?
The SM6T7V5AHM3/H has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per JEDEC standards. This 10% tolerance window ensures predictable avalanche initiation across production lots and temperature extremes, directly supporting robust overvoltage protection design in the SM6T7V5AHM3/H.
Is SM6T7V5AHM3/H qualified for automotive applications?
Yes, the HM3 suffix confirms SM6T7V5AHM3/H is halogen-free, RoHS-compliant, and AEC-Q101 qualified - tested for temperature cycling, high-temperature reverse bias, and ESD per JESD47. It is approved for use in automotive powertrain, body, and chassis modules where SM6T7V5AHM3/H must withstand under-hood thermal and electrical stress.
What does the "H" in SM6T7V5AHM3/H ordering code indicate?
The "H" denotes the preferred package code for 7" diameter plastic tape and reel delivery, containing 750 units per reel. This packaging format is optimized for high-volume SMT placement and aligns with IPC-7351B land pattern recommendations for the SMB (DO-214AA) footprint used by SM6T7V5AHM3/H.
How does SM6T7V5AHM3/H compare to bidirectional TVS diodes like SM6T7V5CA?
The SM6T7V5AHM3/H is unidirectional and features a cathode band for polarity identification, enabling asymmetric clamping (e.g., protecting positive rails only). In contrast, SM6T7V5CA is bidirectional with no polarity marking and identical clamping in both directions - making SM6T7V5AHM3/H preferable for DC-coupled signal lines where reverse conduction must be blocked.
What is the maximum clamping voltage of SM6T7V5AHM3/H under surge conditions?
The SM6T7V5AHM3/H exhibits a maximum clamping voltage (VC) of 11.3 V at 53.0 A peak pulse current using the industry-standard 10/1000 μs waveform. This value is measured under defined thermal conditions and forms the basis for safe margining of protected ICs - confirming that SM6T7V5AHM3/H limits transient overvoltage to well below typical 12 V system damage thresholds.
