Product details
Overview
SMBJ60CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤96.8 V at 6.2 A peak surge current - used in industrial sensor interface protection and automotive ECUs.
For engineers reviewing the SMBJ60CAHE3/52 datasheet, SMBJ60CAHE3/52 pinout, SMBJ60CAHE3/52 application, or SMBJ60CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low Rsurge supports effective energy diversion during ESD or lightning-induced surges.
The device is rated for 600 W peak pulse power under standardized 10/1000 µs waveform conditions, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive underhood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - guaranteed breakdown range ensuring consistent turn-on across production lots. |
| VC @ IPPM | ≤96.8 V at 6.2 A - clamping voltage under full 600 W surge; determines protected circuit's maximum transient exposure. |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IPPM | 6.2 A - peak pulse current corresponding to 600 W at 96.8 V; used for PCB trace sizing and layout derating. |
| TJ max | 150 °C - maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with J-STD-002 soldering. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; no polarity marking for bidirectional configuration - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bidirectional) | AC-coupled transient path | Both terminals function identically; no cathode band marking; connects across protected line and ground or between differential pairs. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-M3/52 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification; same SMB package. | No difference in automotive or industrial use; selected when halogen-free material compliance is mandated by OEM spec. | Choose SMBJ60CA-M3/52 if halogen-free bill-of-materials is required; otherwise SMBJ60CAHE3/52 offers identical performance with standard RoHS compliance. |
| SMCJ60CAHE3/A | Higher-power 1500 W version in larger SMC (DO-214AB) package; same VWM, VBR, and bidirectional functionality. | Used where higher surge repetition rate or longer pulse duration (e.g., IEC 61000-4-4 EFT) demands greater energy absorption. | Choose SMCJ60CAHE3/A only when 600 W is insufficient; requires PCB redesign due to larger 7.11 mm × 6.22 mm footprint. |
Compared with SMBJ60CA-M3/52, the SMBJ60CAHE3/52 offers identical surge performance but without halogen-free certification; compared with SMCJ60CAHE3/A, it delivers proven 600 W protection in a space-constrained SMB footprint - ideal for high-density automotive and industrial PCBs where layout real estate is limited.

FAQ
What is the clamping voltage of SMBJ60CAHE3/52 at its rated peak pulse current?
The SMBJ60CAHE3/52 clamps to a maximum of 96.8 V at its peak pulse current of 6.2 A (corresponding to 600 W with a 10/1000 µs waveform). This value is measured under standardized test conditions and guarantees that downstream circuitry sees no more than 96.8 V during worst-case surge events, making SMBJ60CAHE3/52 suitable for protecting 75 V tolerant interfaces like certain CAN FD transceivers and industrial PLC inputs.
Is SMBJ60CAHE3/52 suitable for automotive applications?
Yes, SMBJ60CAHE3/52 is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It operates reliably from −55 °C to +150 °C and withstands mechanical and thermal stresses defined in the AEC standard, making SMBJ60CAHE3/52 appropriate for engine control units, body electronics, and ADAS sensor modules.
How does the bidirectional design of SMBJ60CAHE3/52 affect its placement on the PCB?
The SMBJ60CAHE3/52 has no polarity marking and functions identically in both directions, so it can be placed across any two nodes requiring symmetrical overvoltage protection - such as differential data lines (RS-485, CAN), AC power inputs, or ungrounded signal pairs. Unlike unidirectional TVS diodes, SMBJ60CAHE3/52 eliminates orientation errors during automated placement and avoids the need for duplicate components on complementary signal paths.
What is the thermal resistance of SMBJ60CAHE3/52, and how does it impact layout?
SMBJ60CAHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. To maintain safe operating temperature under repeated surges, PCB layout must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - as specified in the Vishay datasheet - otherwise thermal derating will reduce effective power handling below 600 W.
Does SMBJ60CAHE3/52 meet moisture sensitivity requirements for lead-free reflow?
Yes, SMBJ60CAHE3/52 meets MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can withstand peak reflow temperatures up to 260 °C without preconditioning or baking. This simplifies SMT manufacturing for high-volume production and eliminates moisture-related defects such as popcorning, confirming SMBJ60CAHE3/52's readiness for modern lead-free assembly processes.
