Product details
Overview
SMCG100CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for high-energy surge protection with 1500 W peak pulse power (10/1000 µs), 100 V standoff voltage (VWM), and clamping voltage of 162 V at 9.3 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines and power rails against inductive switching transients.
For engineers reviewing the SMCG100CAHE3/9AT datasheet, SMCG100CAHE3/9AT pinout, SMCG100CAHE3/9AT application, or SMCG100CAHE3/9AT equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (RθJA = 75 °C/W), DO-215AB mechanical data, and AEC-Q101 qualification status - all critical for automotive-grade ESD/surge protection design-in.
Technical Context
This device operates as a bidirectional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical breakdown (VBR min/max = 111 V / 123 V at 1 mA) ensures identical clamping in both polarities, eliminating polarity-dependent layout constraints.
Rated for -55 °C to +150 °C junction temperature and mounted on 8.0 mm × 8.0 mm copper pads, the SMCG100CAHE3/9AT sustains 1500 W surge power while maintaining 162 V clamping voltage (VC) and exhibits only 1.0 µA max reverse leakage at VWM, enabling low-power system compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before clamping begins; defines upper limit of protected circuit's normal operating range. |
| VBR (min/max) | 111 V / 123 V at 1 mA - Bidirectional breakdown threshold; ensures symmetrical overvoltage triggering in either direction. |
| VC @ IPPM | 162 V at 9.3 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs or MOSFETs. |
| PPPM | 1500 W - Peak pulse power handling capability; supports robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8 mm × 8 mm pads; enables thermal validation without heatsinking in most automotive PCB layouts. |
| TJ max | +150 °C - Maximum junction temperature; confirms suitability for under-hood automotive environments per AEC-Q101 stress testing. |
| AEC-Q101 | Qualified - Validated for automotive reliability including HTOL, TCT, and ESD; required for ECUs, ADAS sensors, and body control modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | Same VWM (100 V) and PPPM (1500 W), but in SMA (DO-214AC) package with higher RθJA (95 °C/W) and no AEC-Q101 qualification. | Limited to industrial/commercial use; unsuitable for automotive due to lack of AEC-Q101 and inferior thermal performance on same pad layout. | Select SMAJ100CA only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated and thermal margin allows higher RθJA. |
| SMCJ100CA | Higher PPPM (1500 W same), but larger SMC (DO-214AB) package, VBR tighter (111–122 V), and AEC-Q101 qualified - however, RθJA is 50 °C/W (better thermal, but requires more board area). | Preferred where higher thermal headroom is needed and PCB space permits larger footprint; suitable for high-reliability industrial motor drives. | Choose SMCJ100CA when thermal derating is critical and board real estate allows DO-214AB; retain SMCG100CAHE3/9AT for space-constrained AEC-Q101 automotive modules. |
Compared with SMAJ100CA and SMCJ100CA, the SMCG100CAHE3/9AT uniquely balances AEC-Q101 compliance, DO-215AB compactness (30 % smaller than SMC), and validated 75 °C/W thermal performance - making it optimal for dense automotive ECUs where qualification, size, and thermal behavior are jointly constrained.

FAQ
What is the clamping voltage of the SMCG100CAHE3/9AT at its rated peak pulse current?
The SMCG100CAHE3/9AT has a maximum clamping voltage (VC) of 162 V at 9.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings. The SMCG100CAHE3/9AT maintains this clamping performance bidirectionally.
Is the SMCG100CAHE3/9AT suitable for automotive applications?
Yes, the SMCG100CAHE3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments with operating junction temperatures up to +150 °C. Its bidirectional architecture, glass-passivated junction, and MSL Level 1 reflow compatibility meet Tier 1 supplier requirements for ECUs, ADAS sensors, and body control modules. The SMCG100CAHE3/9AT is listed in Vishay's AEC-Q101 qualified product portfolio.
What does the "HE3" suffix indicate in SMCG100CAHE3/9AT?
The "HE3" suffix in SMCG100CAHE3/9AT denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It distinguishes this variant from industrial-grade "E3" parts (RoHS, no AEC-Q101) and halogen-free "HM3" versions. The SMCG100CAHE3/9AT is therefore certified for automotive production and meets whisker resistance Class 2 per JESD 201.
How does the SMCG100CAHE3/9AT differ from unidirectional variants like SMCG100A?
The SMCG100CAHE3/9AT is bidirectional (indicated by "CA"), providing symmetrical clamping for AC signals or floating nodes, whereas SMCG100A is unidirectional with cathode marking and forward conduction capability. The SMCG100CAHE3/9AT has no polarity marking, identical VBR in both directions (111–123 V), and is optimized for protecting differential buses or dual-rail systems - unlike SMCG100A, which is intended for DC rail protection with defined anode/cathode orientation.
What is the thermal resistance of the SMCG100CAHE3/9AT under standard mounting conditions?
The SMCG100CAHE3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal - matching the test condition specified in Vishay's datasheet. This value enables accurate thermal modeling for automotive PCBs without additional heatsinking and confirms the SMCG100CAHE3/9AT's suitability for sustained surge duty in confined layouts.
