Product details
Overview
SMBJ60CHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 60 V stand-off 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 motor drives.
For engineers reviewing the SMBJ60CHE3/5B datasheet, SMBJ60CHE3/5B pinout, SMBJ60CHE3/5B application, or SMBJ60CHE3/5B equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, 150 °C max junction temperature, and compatibility with automated SMT placement on PCBs requiring IEC 61000-4-2/4-4/4-5 level ESD/surge protection.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance to low-impedance state during transient overvoltage events, limiting voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at 60 V), while the SMB package supports thermal dissipation up to 5.0 W at 50 °C ambient with RθJA = 100 °C/W.
The SMBJ60CHE3/5B is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). Its temperature coefficient of VBR is +0.105 %/°C, enabling predictable voltage clamping across -55 to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 60 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 66.7–73.7 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 96.8 V at 6.2 A (10/1000 µs) - Peak voltage seen by protected IC/MOSFET during surge; determines minimum required voltage headroom. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability under standardized 10/1000 µs waveform without failure. |
| IPPM (Peak Pulse Current) | 6.2 A - Maximum surge current handled at rated clamping voltage; used to size upstream fusing or current-limiting impedance. |
| TJmax | 150 °C - Maximum junction temperature; sets thermal design limits for PCB copper pad area and power cycling endurance. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and halogen-free (HE3 suffix), MSL Level 1 (260 °C reflow peak).
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60AHE3/5B | Same electrical specs and AEC-Q101 qualification; differs only in base P/N suffix formatting (no "C" in part number). | Identical use cases; no functional distinction in circuit design or layout. | Select based on internal BOM standardization - both are identical devices per Vishay documentation. |
| SMCJ60AHE3/5B | Higher 1500 W PPPM, larger SMC (DO-214AB) package, same VWM/VC but 10.3 A IPPM. | Better suited for higher-energy surges (e.g., 48 V telecom power) where board space allows larger footprint. | Choose SMBJ60CHE3/5B for space-constrained 24 V industrial PCBs; upgrade to SMCJ60AHE3/5B only if >600 W margin is required. |
Compared with SMBJ60AHE3/5B, SMBJ60CHE3/5B offers identical performance and qualification in the same SMB package; versus SMCJ60AHE3/5B, it trades 2.5× lower surge capacity for 30% smaller PCB area and lower thermal mass - critical for dense motor control layouts.

FAQ
What is the clamping voltage of SMBJ60CHE3/5B at its rated peak pulse current?
The SMBJ60CHE3/5B has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs like gate drivers or MCUs remain within absolute maximum ratings. The SMBJ60CHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ60CHE3/5B suitable for automotive applications?
Yes, SMBJ60CHE3/5B is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD47. Its HE3 suffix explicitly denotes automotive-grade qualification, making it appropriate for body electronics, lighting modules, and power distribution units in passenger vehicles. The SMBJ60CHE3/5B's 150 °C max junction temperature and stable VBR drift support operation in engine bay–adjacent locations.
How does the SMBJ60CHE3/5B differ from the SMBJ60AHE3/5B?
SMBJ60CHE3/5B and SMBJ60AHE3/5B are functionally identical devices per Vishay's ordering documentation - both share the same electrical specifications (VWM = 60 V, VC = 96.8 V), AEC-Q101 qualification, SMB package, and RoHS/halogen-free compliance. The "C" in SMBJ60CHE3/5B reflects Vishay's internal revision or marking variant; no performance, reliability, or mechanical difference exists between them. Designers may use either interchangeably without layout or schematic changes.
What is the thermal resistance of SMBJ60CHE3/5B, and how does it affect PCB layout?
The SMBJ60CHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value guides thermal design: for continuous 5.0 W power dissipation, a 50 °C ambient requires ~500 °C rise - which exceeds rating - so the device is intended for transient-only duty. Layout must follow Vishay's specified pad dimensions to ensure reliable solder joint integrity and avoid thermal runaway during surge events.
Does SMBJ60CHE3/5B have polarity markings, and how is it oriented on the PCB?
Yes, SMBJ60CHE3/5B is unidirectional and marked with a cathode band at one end - this band must be oriented toward the higher-potential side of the protected line (e.g., VCC, signal net), while the anode connects to ground or return. Incorrect orientation renders the device ineffective against positive transients. The cathode band aligns with standard SMB (DO-214AA) mechanical drawings and is visible under optical inspection; no additional silkscreen polarity indicators are needed if footprint matches Vishay's recommended land pattern.
