Product details
Overview
SMBG100CA-E3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V maximum clamping voltage (VC) at 3.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the SMBG100CA-E3/52 datasheet, SMBG100CA-E3/52 pinout, SMBG100CA-E3/52 application, or SMBG100CA-E3/52 equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification for automotive use, low incremental surge resistance, 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 identical VBR, VC, and leakage characteristics across reverse and forward directions. Its glass-passivated junction ensures stable breakdown behavior under repetitive transients, while the low-profile SMBG package supports high-density PCB layouts and meets MSL level 1 reflow requirements (260 °C peak).
The device delivers 600 W peak pulse power handling at TA = 25 °C, derated linearly above that temperature per Fig. 2, and sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) - applicable only to unidirectional variants, confirming SMBG100CA-E3/52's exclusive bidirectional operation without forward conduction path definition.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same VWM/VBR/VC specs but lower PPPM = 600 W (same rating), identical SMB package (DO-214AA), slightly larger footprint (4.58 mm × 3.94 mm vs. 6.48 mm × 3.94 mm). | Less effective in high-energy surge environments requiring optimal thermal dissipation; not AEC-Q101 qualified. | Select SMBJ100CA only for cost-sensitive industrial designs where automotive qualification is unnecessary. |
| SMCJ100CA | Higher PPPM = 1500 W, same VWM/VBR, larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), RθJA ≈ 35 °C/W - superior thermal performance. | Better suited for high-power industrial motor drives or solar inverter DC-link protection where sustained surge duty cycles occur. | Choose SMCJ100CA when board space allows and thermal management of >600 W pulses is required. |
Compared with SMBJ100CA and SMCJ100CA, SMBG100CA-E3/52 uniquely balances AEC-Q101 compliance, compact SMBG footprint, and 600 W capability - making it optimal for space-constrained automotive and portable industrial modules where qualification and size are co-prioritized.

FAQ
What is the clamping voltage of SMBG100CA-E3/52 and how is it measured?
The SMBG100CA-E3/52 has a maximum clamping voltage (VC) of 162 V, measured at a peak pulse current (IPPM) of 3.7 A using the standardized 10/1000 μs double-exponential waveform. This value reflects the voltage across the device terminals during worst-case surge conduction and is critical for ensuring downstream components remain below their absolute maximum ratings. The test condition is defined in ANSI/IEEE C62.35 and verified per Vishay Document Number 88456.
Is SMBG100CA-E3/52 suitable for automotive applications?
Yes, SMBG100CA-E3/52 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature operating life, and mechanical shock - specifically intended for automotive electronic systems. Its bidirectional architecture, 100 V stand-off, and 150 °C maximum junction temperature make SMBG100CA-E3/52 appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
Does SMBG100CA-E3/52 have polarity markings on the package?
No, SMBG100CA-E3/52 does not feature polarity markings such as a cathode band because it is a bidirectional TVS diode. Both terminals are functionally identical, enabling symmetrical clamping in either direction - simplifying PCB layout and eliminating orientation errors during automated assembly. This contrasts with unidirectional variants like SMBG100A-E3/52, which include a visible band denoting the cathode end.
What is the thermal resistance of SMBG100CA-E3/52 and how does it affect layout?
SMBG100CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay specification; reducing pad area or omitting thermal vias increases RθJA, risking thermal runaway during repetitive surges. For reliable operation, maintain specified copper area and consider adding thermal vias beneath the package body.
How does SMBG100CA-E3/52 differ from unidirectional SMBG100A-E3/52?
SMBG100CA-E3/52 is bidirectional with symmetrical VBR, VC, and leakage in both directions and no polarity marking, whereas SMBG100A-E3/52 is unidirectional with a cathode band, forward conduction capability (VF = 3.5 V at 50 A), and 100 A IFSM rating. SMBG100CA-E3/52 cannot conduct steady-state forward current and is strictly for AC or differential transient suppression - making it ideal for data line protection where polarity reversal may occur.
