Product details
Overview
SM6T27CAHE3_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 27 V standoff voltage (VWM), 30.6 V minimum breakdown voltage (VBR), 37.5 V maximum clamping voltage at 16 A (10/1000 μs), 600 W peak pulse power, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the SM6T27CAHE3_A/H datasheet, SM6T27CAHE3_A/H pinout, SM6T27CAHE3_A/H application, or SM6T27CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.23), RoHS-compliant + AEC-Q101 qualified construction, and compatibility with automated SMT placement on PCBs requiring IEC 61000-4-2/4-5 level protection.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at 23.1 V), while low-inductance SMB packaging enables fast response to sub-nanosecond ESD events.
The device sustains 600 W peak pulse power per 10/1000 μs waveform under derated conditions up to TJ = 150 °C, with thermal resistance RθJA = 100 °C/W enabling operation without heatsinking in typical 0.2" × 0.2" copper pad layouts. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | 24 V VWM, 26.7 V VBR(min), 38.9 V VC @ 15.4 A; same SMB package but lower clamping voltage rating | Better suited for 24 V nominal systems where tighter clamping margin is critical | Select SMBJ24CA when system operating voltage is strictly ≤24 V and lower VC is prioritized over higher VWM margin |
| SMCJ27CA | 27 V VWM, 30.0 V VBR(min), 45.4 V VC @ 13.2 A; larger SMC (DO-214AB) package with higher thermal mass | Higher power handling (1500 W) but requires more PCB area and has slower response due to higher parasitic inductance | Choose SMCJ27CA only if surge energy exceeds 600 W or board layout allows larger footprint and thermal relief |

FAQ
What is the clamping voltage of SM6T27CAHE3_A/H at rated peak pulse current?
The SM6T27CAHE3_A/H exhibits a maximum clamping voltage (VC) of 37.5 V when subjected to a 10/1000 μs waveform peak pulse current (IPPM) of 16 A. This value is measured under standard test conditions per JEDEC standards and reflects the actual voltage seen by protected circuitry during surge events, ensuring downstream components remain within safe operating limits.
Is SM6T27CAHE3_A/H suitable for automotive applications?
Yes, SM6T27CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-validating reliability in engine control units, body electronics, and ADAS sensors operating from −40 °C to +125 °C ambient.
Does SM6T27CAHE3_A/H have polarity markings on the package?
No, SM6T27CAHE3_A/H is a bidirectional TVS diode and carries no polarity marking such as a cathode band. Its SMB (DO-214AA) package features symmetrical terminals, allowing installation in either orientation-ideal for AC-coupled lines or differential bus protection where polarity independence is required.
What is the maximum operating junction temperature for SM6T27CAHE3_A/H?
The SM6T27CAHE3_A/H has a maximum junction temperature (TJ max) of +150 °C, enabling continuous operation in high-temperature environments such as under-hood automotive locations or enclosed industrial enclosures. Derating curves in the datasheet specify allowable power dissipation reduction above TA = 25 °C to maintain this limit.
How does the 600 W peak pulse power rating of SM6T27CAHE3_A/H translate to real-world surge immunity?
The 600 W rating for SM6T27CAHE3_A/H corresponds to standardized 10/1000 μs surge waveforms defined in IEC 61000-4-5. At 23.1 V standoff, this supports peak currents up to 16 A-sufficient for Level 3 (1 kV line-to-ground) surge testing in automotive and industrial equipment, provided PCB layout follows recommended 0.2" × 0.2" copper pads per terminal.
