Product details
Overview
SMBG60CA-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 or 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), <120 V clamping voltage at rated surge current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG60CA-E3/52 datasheet, SMBG60CA-E3/52 pinout, SMBG60CA-E3/52 application, or SMBG60CA-E3/52 equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and RoHS-compliant industrial packaging with matte tin leads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, IPPM, and VC specifications for positive and negative surges. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), enabling protection of high-speed interfaces without signal distortion.
The device uses a low-inductance SMBG (DO-215AA) surface-mount package with 0.235" × 0.255" footprint and meets MSL level 1 (260 °C reflow peak). Thermal performance is defined by RθJA = 100 °C/W (on 5.0 mm × 5.0 mm copper pads) and RθJL = 20 °C/W, supporting sustained surge handling in compact automotive and industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin for 48 V systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold across production lot; ensures consistent turn-on under ESD or lightning-induced transients. |
| VC @ IPPM | ≤120 V at 5.0 A - Clamped voltage during 10/1000 µs surge; limits stress on downstream ICs like CAN transceivers or microcontrollers. |
| PPPM | 600 W - Peak pulse power rating; supports repetitive 0.01% duty cycle surges per JEDEC standards. |
| IPPM | 5.0 A - Peak pulse current corresponding to VC; derived from 600 W / 120 V, validated per Fig. 1 curve. |
| TJ Range | −55 °C to +150 °C - Full automotive-grade junction temperature range; enables operation in engine bay or under-hood environments. |
| Leakage ID | ≤1.0 µA at 60 V - Ultra-low reverse leakage preserves signal integrity on high-impedance sensor lines. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | Same VWM/VBR/PPPM, but SMB (DO-214AA) package (larger footprint, higher RθJA = 130 °C/W) | Less suitable for space-constrained automotive modules; requires larger pad layout. | Select SMBJ60CA only if board area allows and thermal budget permits higher junction rise. |
| SMCJ60CA | Same electrical specs, but SMC (DO-214AB) package (higher PPPM = 1500 W, RθJA = 60 °C/W) | Better for high-energy surges (e.g., ISO 16750-2), but incompatible with SMBG land pattern. | Choose SMCJ60CA when system-level testing demands >600 W surge margin and PCB real estate permits larger package. |
Compared with SMBJ60CA and SMCJ60CA, SMBG60CA-E3/52 offers optimal balance of 600 W surge capability, AEC-Q101 qualification, and minimal 6.5 mm × 4.6 mm footprint-making it preferred for next-generation automotive domain controllers and compact industrial edge nodes where board space and thermal management are tightly constrained.

FAQ
What is the maximum clamping voltage of SMBG60CA-E3/52 at its rated peak pulse current?
The SMBG60CA-E3/52 has a maximum clamping voltage (VC) of 120 V at its rated peak pulse current (IPPM) of 5.0 A under a 10/1000 µs waveform. This value is measured per Figure 1 and Table 1 in Vishay Document 88456 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG60CA-E3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG60CA-E3/52 suitable for automotive applications?
Yes, SMBG60CA-E3/52 is AEC-Q101 qualified and explicitly rated for automotive use per Vishay's documentation. Its −55 °C to +150 °C junction temperature range, MSL Level 1 reflow compatibility, and bidirectional 600 W surge capability meet requirements for engine control units, body electronics, and ADAS sensor interfaces. The SMBG60CA-E3/52 carries the HE3 suffix variant for full AEC-Q101 compliance, and the E3/52 version shares identical electrical and thermal specs.
How does the SMBG60CA-E3/52 differ from unidirectional SMBG60A-E3/52?
The SMBG60CA-E3/52 is bidirectional with symmetrical clamping in both polarities and no polarity marking, whereas SMBG60A-E3/52 is unidirectional with a cathode band and only clamps positive transients. Key differences include VBR test direction (bidirectional vs. anode-to-cathode), absence of forward voltage (VF) spec in SMBG60CA-E3/52, and distinct marking codes (NK vs. NK for unidirectional). The SMBG60CA-E3/52 is selected when protection is required on AC-coupled or differential lines like CAN or RS-485.
What is the thermal resistance of SMBG60CA-E3/52, and how is it measured?
The SMBG60CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per JEDEC JESD51-3. Its junction-to-lead resistance (RθJL) is 20 °C/W. These values define temperature rise under steady-state or repetitive surge conditions and are critical for calculating safe operating area in high-duty-cycle applications using the SMBG60CA-E3/52.
Does SMBG60CA-E3/52 require a heatsink for standard surge protection use?
No, the SMBG60CA-E3/52 does not require an external heatsink for single-event or low-duty-cycle (0.01%) surge protection, as its 600 W rating is validated with standard PCB copper pads. However, for repetitive surges above 0.01% duty cycle or ambient temperatures exceeding 85 °C, thermal design must account for RθJA = 100 °C/W and junction temperature limits. The SMBG60CA-E3/52 relies on PCB copper mass-not heatsinks-for thermal dissipation in typical applications.
