Product details
Overview
SMBG60CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of signal and power lines. It features 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 96.8 V at 6.2 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG60CA-E3/5B datasheet, SMBG60CA-E3/5B pinout, SMBG60CA-E3/5B application, or SMBG60CA-E3/5B equivalent, key selection criteria include bidirectional surge clamping performance, junction temperature derating above 25 °C, compliance with UL 497B and IEC 61000-4-5, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during transients, conducting when reverse voltage exceeds VBR to limit downstream voltage to ≤96.8 V. Its glass-passivated junction ensures stable leakage (<1.0 µA at 60 V) and fast response time (<1 ns), critical for protecting sensitive ICs against ESD and inductive switching spikes.
The SMBG60CA-E3/5B is rated for repetitive 10/1000 µs surges at 0.01% duty cycle, with thermal resistance RθJA = 100 °C/W and maximum junction temperature of +150 °C. Its bidirectional symmetry eliminates polarity concerns in AC-coupled or differential signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal swing range. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold ensuring reliable turn-on under surge conditions. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage during 600 W transient; determines maximum stress on protected circuitry. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; validates immunity to IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | <1.0 µA - Ultra-low leakage at rated stand-off voltage, preserving signal integrity in high-impedance sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | Same VWM (60 V) and VC (96.8 V), but lower PPPM = 600 W (same rating), different package (SMB/DO-214AA); slightly larger footprint (4.58 mm × 3.94 mm vs. SMBG's 4.57 mm × 3.94 mm). | Not AEC-Q101 qualified; intended for industrial/commercial use only. | Select SMBJ60CA if AEC-Q101 is not required and existing PCB uses SMB pad layout. |
| SMCJ60CA | Higher PPPM = 1500 W, same VWM/VC, larger SMC (DO-214AB) package; RθJA = 25 °C/W vs. 100 °C/W for SMBG60CA-E3/5B. | Used where higher single-pulse energy absorption is needed (e.g., DC power input rails), but requires more board area and thermal management. | Choose SMCJ60CA when surge threat level exceeds 600 W or junction temperature rise must be minimized under sustained stress. |
Compared with SMBJ60CA and SMCJ60CA, the SMBG60CA-E3/5B uniquely combines AEC-Q101 qualification, SMBG's compact DO-215AA footprint, and 600 W clamping in a single-source automotive-qualified solution-making it optimal for space-constrained, high-reliability vehicle subsystems.

FAQ
What is the maximum clamping voltage of SMBG60CA-E3/5B under a 600 W transient?
The SMBG60CA-E3/5B clamps to 96.8 V at its peak pulse current of 6.2 A, corresponding to the 600 W 10/1000 µs waveform. This value is measured and guaranteed per the Vishay datasheet (Document Number: 88456, Rev. 09-Jan-2024), and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is SMBG60CA-E3/5B suitable for bidirectional signal lines like CAN or RS-485?
Yes, SMBG60CA-E3/5B is explicitly designed for bidirectional applications, as indicated by the "CA" suffix and confirmed in the Vishay datasheet. Its symmetrical breakdown behavior (VBR = 66.7–73.7 V in both directions) makes it ideal for protecting differential buses such as CAN FD and RS-485 without polarity constraints-no marking is applied to the SMBG package since polarity is irrelevant.
Does SMBG60CA-E3/5B meet automotive reliability standards?
Yes, SMBG60CA-E3/5B carries AEC-Q101 qualification (noted in the mechanical data section and footnote 1 of the Vishay datasheet). This includes validation for temperature cycling, highly accelerated life testing (HALT), and ESD robustness-ensuring suitability for under-hood and chassis-mounted automotive electronics where junction temperatures reach +150 °C.
What is the leakage current specification for SMBG60CA-E3/5B at its rated stand-off voltage?
At VWM = 60 V and TA = 25 °C, the SMBG60CA-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA. This ultra-low leakage preserves signal fidelity in high-impedance sensor interfaces and battery-powered systems, and is verified per the electrical characteristics table in the official Vishay datasheet.
Can SMBG60CA-E3/5B be used in UL 497B-compliant telecom designs?
Yes, SMBG60CA-E3/5B holds Underwriters Laboratories recognition (file number E136766) for protectors under UL 497B, covering both unidirectional and bidirectional configurations. This certification confirms its suitability for primary-side surge protection in telecom line cards, DSL modems, and PoE-powered equipment meeting North American safety requirements.
