Product details
Overview
SM6T7V5AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in SMB (DO-214AA) package, with 7.13 V minimum breakdown voltage (VBR), 6.40 V standoff voltage (VWM), and 600 W peak pulse power (10/1000 μs). It clamps transients to 11.3 V at 53 A, and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the SM6T7V5AHM3_B/H datasheet, SM6T7V5AHM3_B/H pinout, SM6T7V5AHM3_B/H application, or SM6T7V5AHM3_B/H equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, low-inductance SMB package, and compliance with automotive reliability standards.
Technical Context
The SM6T7V5AHM3_B/H operates as a unidirectional TVS diode optimized for fast clamping of ESD and inductive switching transients. Its glass-passivated junction ensures stable breakdown behavior, while the SMB package provides low thermal resistance (RθJL = 20 °C/W) and meets MSL Level 1 (260 °C reflow).
Designed for surge immunity per IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT), it delivers 11.3 V clamping voltage at 53 A IPPM (10/1000 μs), with reverse leakage ≤500 μA at 6.40 V and maximum junction temperature of +150 °C.

|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients up to ±35 V and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power rail and ground, absorbing surge energy before it reaches regulator or MCU inputs. Use Value: Limits voltage to 11.3 V during 53 A surges, preventing latch-up or permanent damage to 5 V/3.3 V logic circuitry. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to PLC I/O modules against field wiring transients. IC Role / Device Role / Timing Role: Point-of-entry protection on signal lines, shunting induced spikes to ground before reaching ADC front-end or op-amp buffers. Use Value: Maintains signal integrity by clamping transients within 1 ns response time, with <500 μA leakage at 6.4 V ensuring minimal offset error. |
| Consumer Device USB Port Protection | Telecom Base Station DC Power Input |
Use Scenario: ESD protection on VBUS and D+/D− lines of USB 2.0 ports in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on power and data lines, grounded via short PCB traces. Use Value: Withstands ±15 kV contact ESD (IEC 61000-4-2) without degradation, preserving signal rise time due to low package inductance. | Use Scenario: Secondary-side transient suppression on -48 V DC input rails of telecom remote radio units exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS in parallel with bulk capacitance, clamping fast-rising surges before they propagate into DC/DC converters. Use Value: 600 W rating enables robust protection against 10/1000 μs lightning surges while maintaining 6.4 V nominal rail integrity. |
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 VWM, 12.0 V VC @ 50 A; lower PPPM (400 W); no AEC-Q101 qualification | Commercial-grade only; not validated for automotive temperature cycling or humidity testing | Select when cost-sensitive non-automotive designs require basic 7.5 V clamping with reduced surge margin |
| SMCJ7.0A | Larger SMC (DO-214AB) package; 7.0 V VWM, 11.2 V VC @ 53.5 A; PPPM = 1500 W; AEC-Q101 available (HM3 suffix) | Higher power handling but requires larger PCB area; better suited for primary-side or high-energy surge zones | Choose when system-level surge tests exceed 600 W or when layout allows SMC footprint for improved thermal dissipation |
Compared with SMAJ7.5A and SMCJ7.0A, the SM6T7V5AHM3_B/H uniquely balances AEC-Q101 qualification, SMB footprint, and precise 6.4 V/7.13 V voltage grading-making it optimal for space-constrained automotive modules where qualification and form factor are jointly critical.

FAQ
What is the exact breakdown voltage range for SM6T7V5AHM3_B/H?
The SM6T7V5AHM3_B/H has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, per Vishay's 88385 datasheet revision 09-Jan-2024. This range ensures predictable turn-on behavior for 6.40 V nominal circuits while accommodating process variation without compromising protection margin.
Is SM6T7V5AHM3_B/H suitable for bidirectional transient protection?
No, SM6T7V5AHM3_B/H is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., SM6T7V5CA). Using SM6T7V5AHM3_B/H in AC or floating signal paths would result in forward conduction during negative transients, potentially damaging the device or circuit.
Does SM6T7V5AHM3_B/H meet automotive qualification standards?
Yes, SM6T7V5AHM3_B/H carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. This certification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-validating its use in automotive powertrain, chassis, and body control modules.
What is the maximum clamping voltage of SM6T7V5AHM3_B/H under surge conditions?
The SM6T7V5AHM3_B/H clamps to a maximum of 11.3 V at 53 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC guidelines and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
How does the SMB package of SM6T7V5AHM3_B/H affect PCB layout?
The SMB (DO-214AA) package of SM6T7V5AHM3_B/H requires a specific pad layout: 0.220" × 0.155" overall footprint with 0.086" minimum cathode/anode pad width and 0.220" reference length. Proper pad sizing ensures thermal reliability and solder joint integrity during reflow, especially critical for AEC-Q101 applications where mechanical stress endurance is tested.
