Product details
Overview
SM6T7V5CAHE3_A/H 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/H datasheet, SM6T7V5CAHE3_A/H pinout, SM6T7V5CAHE3_A/H application, or SM6T7V5CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.59), thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown tested using 300 μs square-wave pulses per JEDEC standards. Its glass-passivated junction ensures stable leakage (<500 μA at VWM) and robust surge handling up to 150 °C junction temperature.
The device delivers consistent clamping performance under repetitive 10/1000 μs transients when mounted per recommended pad layout, and meets MSL Level 1 reflow profile (peak 260 °C), supporting high-reliability automotive PCB assembly without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 7.13 V - guaranteed breakdown initiation threshold under 10 mA test current, defining earliest clamping onset |
| VWM | 6.40 V - maximum continuous reverse voltage before significant leakage, sets operating margin below breakdown |
| VC @ IPPM | 11.3 V at 53.0 A - clamped voltage during 600 W transient, determines protected circuit's worst-case overvoltage stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform, defines surge energy absorption capacity |
| ID @ VWM | ≤500 μA - reverse leakage at standoff voltage, critical for low-power sensor line integrity |
| TJ max | +150 °C - maximum junction temperature, enables operation in under-hood automotive environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient, informs heatsinking requirements on standard PCB pads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5CA | Same SMB package, but lower 400 W PPPM, higher VC = 12.0 V at 33.3 A, non-AEC-Q101 | Limited to commercial-grade industrial or consumer use; not qualified for automotive under-hood deployment | Select SMAJ7.5CA only if surge energy is ≤400 W and AEC-Q101 compliance is not required. |
| 1.5KE7.5CA | Higher PPPM = 1500 W, DO-201 package (larger footprint), VC = 12.0 V at 125 A, non-SMT | Requires through-hole mounting and larger board area; unsuitable for dense automotive PCBs | Choose 1.5KE7.5CA only when peak surge current exceeds 53 A and board space allows axial-leaded components. |
Compared with SMAJ7.5CA and 1.5KE7.5CA, SM6T7V5CAHE3_A/H uniquely combines AEC-Q101 qualification, 600 W capability in compact SMB, and 11.3 V clamping - making it optimal for space-constrained automotive and industrial SMT designs requiring validated reliability.

FAQ
What does the "CA" suffix indicate in SM6T7V5CAHE3_A/H?
The "CA" suffix in SM6T7V5CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SM6T7V5A), SM6T7V5CAHE3_A/H has no cathode marking and functions identically across either polarity - essential for protecting AC-coupled or differential signal lines where polarity reversal may occur.
Is SM6T7V5CAHE3_A/H qualified for automotive applications?
Yes, SM6T7V5CAHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3", which designates RoHS-compliant and AEC-Q101-qualified versions. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, validating its suitability for under-hood and chassis-mounted automotive electronics per ISO/TS 16949 requirements.
What is the clamping voltage of SM6T7V5CAHE3_A/H under surge conditions?
The maximum clamping voltage (VC) of SM6T7V5CAHE3_A/H is 11.3 V when subjected to a 10/1000 μs transient waveform at 53.0 A peak pulse current (IPPM). This value is measured per Figure 1 in Vishay document 88385 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
How does the SMB (DO-214AA) package of SM6T7V5CAHE3_A/H affect PCB layout?
The SMB (DO-214AA) package of SM6T7V5CAHE3_A/H requires a minimum 5.0 mm × 5.0 mm copper pad per terminal for rated 600 W pulse power dissipation, per Vishay's thermal derating curve. Its 4.57 mm × 3.94 mm footprint supports high-density SMT placement, and the absence of polarity marking simplifies layout routing for bidirectional protection schemes.
What is the standoff voltage (VWM) of SM6T7V5CAHE3_A/H, and why does it matter?
The standoff voltage (VWM) of SM6T7V5CAHE3_A/H is 6.40 V - the maximum continuous reverse voltage the device can block without exceeding 500 μA leakage current. This parameter ensures minimal loading on 5 V or 3.3 V signal lines while providing sufficient margin below the 7.13 V minimum breakdown voltage to prevent false triggering during normal operation.
