Product details
Overview
SMBG100CAHE3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on signal or power lines. It features a 100 V standoff voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), 3.7 A maximum reverse leakage at VWM, and 162 V clamping voltage (VC) at 3.7 A peak pulse current - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMBG100CAHE3/52 datasheet, SMBG100CAHE3/52 pinout, SMBG100CAHE3/52 application, or SMBG100CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, low-profile SMBG package compatibility with automated SMT placement, and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a silicon avalanche diode with symmetrical bidirectional conduction, enabling suppression of both positive and negative polarity transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The SMBG100CAHE3/52 delivers 600 W peak pulse power handling per 10/1000 µs waveform at 0.01 % duty cycle, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting operation from –55 °C to +150 °C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA-E3/52 | Same VWM/VBR/VC specs but lower PPPM (600 W vs. SMBJ's 600 W - identical rating); differs in package thermal resistance (RθJA = 100 °C/W same, but RθJL = 20 °C/W same) and JEDEC qualification level (SMBJ not AEC-Q101 qualified) | Not certified for automotive use; suitable for industrial/commercial only | Select SMBG100CAHE3/52 when AEC-Q101 compliance is mandatory; choose SMBJ100CA-E3/52 for cost-sensitive non-automotive designs |
| SMCJ100CAHE3/52 | Higher PPPM (1500 W), larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), same VWM/VBR/VC, higher IPPM (12.3 A), same AEC-Q101 qualification | Requires more PCB area but handles higher-energy transients (e.g., ISO 16750-2 load dump) | Choose SMBG100CAHE3/52 for space-constrained automotive modules; select SMCJ100CAHE3/52 where surge energy exceeds 600 W capability |
Compared with SMBJ100CA-E3/52 and SMCJ100CAHE3/52, the SMBG100CAHE3/52 uniquely balances AEC-Q101 qualification, 600 W surge capacity, and compact SMBG footprint - making it optimal for automotive body control modules and ADAS sensor nodes where board area and qualification are jointly critical.

FAQ
What is the standoff voltage rating of the SMBG100CAHE3/52?
The SMBG100CAHE3/52 has a standoff voltage (VWM) of 100 V - the maximum DC or continuous reverse voltage the device can withstand without entering avalanche breakdown. This value is confirmed in the Vishay datasheet Document Number 88456, Table "ELECTRICAL CHARACTERISTICS", row for SMBG100A/SMBG100CA. Operation above this voltage initiates clamping action.
Is the SMBG100CAHE3/52 suitable for automotive applications?
Yes, the SMBG100CAHE3/52 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 09-Jan-2024, Section "MECHANICAL DATA" and "ORDERING INFORMATION". This certification validates its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces under temperature cycling, humidity, and surge stress conditions.
What is the clamping voltage of the SMBG100CAHE3/52 at its rated peak pulse current?
The SMBG100CAHE3/52 exhibits a maximum clamping voltage (VC) of 162 V at its rated peak pulse current (IPPM) of 3.7 A, measured using the standard 10/1000 µs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet (Document Number 88456, page 2) for the SMBG100A variant, which applies identically to SMBG100CAHE3/52 as a bidirectional member of the same family.
Does the SMBG100CAHE3/52 have polarity markings on its package?
No, the SMBG100CAHE3/52 does not have polarity markings because it is a bidirectional TVS diode. As confirmed in the Vishay datasheet section "MECHANICAL DATA": "no marking on bidirectional types". Both terminals are functionally identical, allowing flexible placement on PCBs without orientation constraints - unlike unidirectional variants that feature a cathode band.
What package type does the SMBG100CAHE3/52 use, and what are its key mechanical dimensions?
The SMBG100CAHE3/52 uses the SMBG (DO-215AA) package, with mechanical dimensions of 5.97 mm × 4.06 mm body length/width and 2.16 mm maximum height, per the "PACKAGE OUTLINE DIMENSIONS" drawing in the Vishay datasheet (page 5). The package features matte tin-plated leads, UL 94 V-0 compliant molding compound, and MSL Level 1 rating for lead-free reflow compatibility.
