Product details
Overview
SMBG10CA-E3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on signal and power lines. It features 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the SMBG10CA-E3/52 datasheet, SMBG10CA-E3/52 pinout, SMBG10CA-E3/52 application, or SMBG10CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.7), TJ max. of +150 °C, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable avalanche characteristics and low leakage (<5.0 μA at VWM), while the low incremental surge resistance enables effective energy diversion during fast transients.
The SMBG10CA-E3/52 delivers consistent clamping performance across -55 °C to +150 °C operating range and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Its 100 °C/W junction-to-ambient thermal resistance requires appropriate copper pad area (0.2" × 0.2") for rated 600 W pulse handling.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same VWM (10 V), but lower PPPM (600 W vs. SMBJ's 600 W - identical rating); slightly higher VC (17.0 V vs. SMBJ10CA's 17.0 V - same), identical DO-214AA package footprint but different leadform | DO-214AA (SMB) vs. DO-215AA (SMBG): 0.2 mm wider body and 0.1 mm longer leads on SMBG improve thermal dissipation margin | Select SMBG10CA-E3/52 when board layout allows SMBG footprint and higher thermal reliability is required for automotive or industrial use. |
| 1.5SMC10CA | Same VWM and bidirectional function, but larger SMC (DO-214AB) package; higher thermal mass yields better 10/1000 μs pulse handling margin at elevated ambient temperatures | Requires larger PCB area (7.1 mm × 6.2 mm vs. SMBG's 4.57 mm × 3.94 mm); not suitable for space-constrained designs | Choose 1.5SMC10CA only when sustained surge repetition or >125 °C ambient operation demands extra thermal headroom beyond SMBG10CA-E3/52 capability. |
Compared with SMBJ10CA and 1.5SMC10CA, SMBG10CA-E3/52 offers optimal balance of compact size, AEC-Q101 qualification, and verified 600 W surge capacity - making it preferred for automotive-grade SMT designs where footprint and qualification are decisive.

FAQ
What is the clamping voltage of SMBG10CA-E3/52 at its rated peak pulse current?
The SMBG10CA-E3/52 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG10CA-E3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG10CA-E3/52 suitable for automotive applications?
Yes, SMBG10CA-E3/52 is AEC-Q101 qualified and specifically designed for automotive use. It meets stringent stress testing requirements including temperature cycling, humidity bias, and high-temperature reverse bias - validating its suitability for engine control units, body electronics, and ADAS sensor interfaces. The SMBG10CA-E3/52 also supports MSL Level 1 reflow and operates reliably from -55 °C to +150 °C junction temperature.
How does the SMBG10CA-E3/52 differ from unidirectional TVS diodes like SMBG10A-E3/52?
The SMBG10CA-E3/52 is bidirectional, meaning it clamps voltage transients of either polarity symmetrically, while SMBG10A-E3/52 is unidirectional and only protects against positive-going surges relative to cathode. The SMBG10CA-E3/52 has no polarity marking and is used where AC signals, floating grounds, or bidirectional data lines require protection - such as CAN, RS-485, or Ethernet interfaces. Its breakdown voltage spec applies identically in both directions.
What is the recommended PCB pad layout for SMBG10CA-E3/52 to achieve full 600 W rating?
To achieve the full 600 W peak pulse power rating, SMBG10CA-E3/52 must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay's datasheet Figure 2. These pads provide necessary thermal mass to dissipate surge energy without exceeding TJ max. of +150 °C. Smaller pads will derate PPPM significantly - e.g., 0.1" × 0.1" pads reduce capability to ~200 W.
Does SMBG10CA-E3/52 have a specified junction capacitance for high-speed signal line protection?
Vishay does not publish a guaranteed junction capacitance (CJ) value for SMBG10CA-E3/52 in the SMBG5.0A–SMBG188CA datasheet. However, typical CJ for comparable SMBG-series bidirectional TVS devices at 0 V bias and 1 MHz is below 100 pF - sufficient for <10 Mbps digital lines. For high-speed interfaces (>100 Mbps), designers should verify signal integrity empirically or consider lower-capacitance alternatives, as the SMBG10CA-E3/52 is optimized for power/signal-line surge rather than RF performance.
