Product details
Overview
SMBJ60CA-M3/5B 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 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 - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ60CA-M3/5B datasheet, SMBJ60CA-M3/5B pinout, SMBJ60CA-M3/5B application, or SMBJ60CA-M3/5B equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.45), halogen-free RoHS-compliant construction (M3 suffix), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
The device is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and exhibits a VBR temperature coefficient of +0.105 %/°C - enabling predictable performance across automotive and industrial thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 48 V DC bus protection. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - guaranteed breakdown range ensures reliable triggering above system overvoltage thresholds. |
| VC @ IPPM | 96.8 V at 6.2 A - clamping voltage limits downstream component stress during 600 W transient events. |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform supports IEC 61000-4-5 Level 4 surge immunity. |
| IPPM | 6.2 A - peak pulse current capacity derived from VC and PPPM; confirms robustness against common lightning-induced surges. |
| TJ max. | +150 °C - high junction temperature rating allows operation in enclosed industrial enclosures without derating. |
| Package | SMB (DO-214AA) - standardized 2-pin surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height for high-density PCB layouts. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (negative polarity) | Accepts surge current during negative-going transients; symmetrical with cathode for bidirectional operation. |
| Cathode | Transient current entry point (positive polarity) | Accepts surge current during positive-going transients; functionally identical to anode in bidirectional mode. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables compliance with IEC 61000-4-5 surge immunity requirements for industrial equipment up to Level 4 (4 kV line-to-line). |
| Bidirectional clamping symmetry | Eliminates need for polarity-aware layout; protects AC-coupled or floating signal lines without external diode pairing. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and EU Directive 2015/863 for restricted substances. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; compatible with high-throughput SMT assembly lines. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs. |

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-E3/5B | Same electrical specs; RoHS-compliant but contains brominated flame retardants (non-halogen-free). | Approved for commercial-grade systems where halogen-free mandate does not apply (e.g., non-automotive consumer devices). | Select when cost sensitivity outweighs halogen-free requirement and AEC-Q101 qualification is unnecessary. |
| SMAJ60CA-M3 | Lower 400 W PPPM, larger 3.5 mm × 4.5 mm SMA package, higher VC = 96.8 V at 4.2 A. | Suitable for lower-energy transients; requires larger PCB area and offers reduced surge margin vs. SMBJ series. | Choose only if existing SMA footprint reuse is mandatory and 400 W rating suffices for target surge profile. |
Compared with SMBJ60CA-E3/5B, the SMBJ60CA-M3/5B provides halogen-free compliance without sacrificing electrical performance; versus SMAJ60CA-M3, it delivers 50% higher surge power handling in a more compact SMB outline - critical for space-constrained 48 V telecom and industrial control designs.

FAQ
What is the clamping voltage of SMBJ60CA-M3/5B at its rated peak pulse current?
The SMBJ60CA-M3/5B has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 96.8 V during worst-case transient events. The SMBJ60CA-M3/5B maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is SMBJ60CA-M3/5B suitable for automotive applications?
The SMBJ60CA-M3/5B itself is commercial-grade and not AEC-Q101 qualified; however, it shares identical electrical and mechanical specifications with the AEC-Q101 qualified variant SMBJ60CAHM3_B/I. For non-safety-critical automotive subsystems (e.g., infotainment power rails, body electronics), SMBJ60CA-M3/5B may be used subject to customer validation. The SMBJ60CA-M3/5B is halogen-free and RoHS-compliant, aligning with automotive material compliance requirements.
How does the bidirectional design of SMBJ60CA-M3/5B affect PCB layout?
The SMBJ60CA-M3/5B has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout by removing the need for silkscreen polarity indicators or directional routing - especially beneficial for differential signal lines, AC-coupled interfaces, or floating grounds. The SMBJ60CA-M3/5B's symmetric behavior ensures consistent clamping regardless of transient polarity, reducing design iteration cycles.
What is the thermal resistance of SMBJ60CA-M3/5B, and how does it impact power dissipation?
The SMBJ60CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. At ambient temperatures up to +85 °C, this allows continuous power dissipation up to 5.0 W. For transient events, the device relies on short-duration thermal mass rather than steady-state conduction - meaning the SMBJ60CA-M3/5B handles 600 W surges without overheating due to its low thermal impedance pulse response.
Can SMBJ60CA-M3/5B replace unidirectional TVS diodes in existing designs?
The SMBJ60CA-M3/5B is bidirectional and cannot directly replace unidirectional TVS diodes (e.g., SMBJ60A-M3/5B) in circuits relying on DC blocking or polarity-specific clamping. However, it can substitute unidirectional parts in AC-coupled, floating, or dual-rail applications where symmetric protection is acceptable - provided layout accommodates the absence of cathode band marking. Always verify VBR and VC alignment with system voltage margins before substituting SMBJ60CA-M3/5B.
