Product details
Overview
SMBJ60CA-M3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in industrial sensor interfaces.
For engineers reviewing the SMBJ60CA-M3/52 datasheet, SMBJ60CA-M3/52 pinout, SMBJ60CA-M3/52 application, or SMBJ60CA-M3/52 equivalent, this device is selected for bidirectional surge suppression where low clamping ratio, fast response (<1 ps), and AEC-Q101-compliant variants (HM3 suffix) are critical in automotive body control modules, industrial PLC I/O protection, and telecom line interface circuits.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection against positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1 µA at VWM), while the 20 °C/W junction-to-lead thermal resistance supports reliable energy dissipation during repetitive surges.
The device complies with ANSI/IEEE C62.35 for transient suppressor characterization and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C lead-free reflow compatibility. Its 150 °C maximum junction temperature and -55 °C to +150 °C operating range support deployment in extended-temperature industrial and automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 60 V - Maximum continuous reverse operating voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensuring predictable turn-on during transients; ±5% tolerance enables precise system-level margining. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability; validates suitability for IEC 61000-4-5 Level 4 (4 kV) surge testing with proper PCB layout. |
| IPPM | 6.2 A - Peak pulse current supported at rated clamping voltage; used to size series impedance and verify coordination with upstream fusing. |
| TJ max. | +150 °C - Maximum junction temperature; allows operation in high-ambient environments such as motor drives or power supplies without derating. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated pick-and-place and reflow. |

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-E3/52 | Same electrical specs; RoHS-compliant but not halogen-free; tin-lead solderable per J-STD-002. | Preferred for commercial-grade, non-automotive designs where halogen content is unrestricted. | Select when cost-sensitive commercial production requires standard RoHS compliance without halogen-free mandate. |
| SMBJ60CAHM3_B/I | AEC-Q101 qualified; identical VWM, VBR, VC, and PPPM; same SMB package with enhanced reliability screening. | Required for automotive applications subject to AEC-Q101 qualification (e.g., body electronics, infotainment). | Choose for automotive OEM or Tier-1 programs needing certified reliability and traceable lot documentation. |
Compared with SMBJ60CA-M3/52, the E3/52 variant offers lower cost for non-halogen-restricted use, while the HM3_B/I version adds AEC-Q101 validation for automotive deployment - neither is pin-compatible with unidirectional SMBJ60A variants due to fundamental polarity architecture differences.

FAQ
What is the clamping voltage of SMBJ60CA-M3/52 at its rated peak pulse current?
The SMBJ60CA-M3/52 has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ60CA-M3/52 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C), making it suitable for demanding industrial and automotive applications.
Is SMBJ60CA-M3/52 suitable for automotive applications?
The SMBJ60CA-M3/52 itself is not AEC-Q101 qualified; it is a commercial-grade, halogen-free, RoHS-compliant part. However, Vishay offers the functionally identical SMBJ60CAHM3_B/I variant - which carries AEC-Q101 qualification - for automotive use. Engineers selecting SMBJ60CA-M3/52 should verify that their application does not require automotive qualification; if so, SMBJ60CAHM3_B/I must be specified instead. The SMBJ60CA-M3/52 remains appropriate for industrial and telecom systems where AEC-Q101 is not mandated.
How does the bidirectional design of SMBJ60CA-M3/52 affect its circuit placement?
The SMBJ60CA-M3/52 has no polarity marking and operates identically in both directions, allowing placement across any two nodes requiring symmetrical overvoltage protection - such as between signal and ground, power and ground, or differential lines. Unlike unidirectional TVS diodes, it eliminates orientation errors during assembly and simplifies layout for AC-coupled or floating interfaces. This symmetry is intrinsic to the SMBJ60CA-M3/52's internal structure and is validated across its full VBR and VC specifications in both polarities.
What is the thermal resistance of SMBJ60CA-M3/52, and how does it impact power handling?
The SMBJ60CA-M3/52 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from the silicon die to the PCB copper pads. When mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, this RθJL supports reliable dissipation of its 600 W peak pulse power without thermal runaway. The SMBJ60CA-M3/52's 100 °C/W junction-to-ambient rating (RθJA) further informs steady-state derating - though its primary function is transient, not continuous, power handling.
Does SMBJ60CA-M3/52 meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the SMBJ60CA-M3/52 meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C, meaning it can be processed in standard lead-free reflow ovens without prebaking. This MSL Level 1 rating is confirmed in the Vishay datasheet (Document Number: 88392, Revision: 09-Jan-2024) and applies to all M3-suffix parts. The SMBJ60CA-M3/52's halogen-free molding compound and matte tin-plated leads also comply with J-STD-002 solderability standards, ensuring robust manufacturability.
