Product details
Overview
SMBJ150CHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 150 V standoff voltage (VWM), 167–185 V breakdown range (VBR at 1 mA), 243 V clamping voltage (VC) at 2.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, microcontrollers, and sensor interfaces in industrial motor drives and telecom power supplies.
For engineers reviewing the SMBJ150CHE3/5B datasheet, SMBJ150CHE3/5B pinout, SMBJ150CHE3/5B application, or SMBJ150CHE3/5B equivalent, key selection criteria include its AEC-Q101 qualification, low thermal resistance (RθJL = 20 °C/W), 150 °C max junction temperature, unidirectional polarity with cathode band marking, and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a clamping device: under normal conditions it presents high impedance (>1 µA leakage at 150 V), but triggers into low-impedance conduction when transient voltage exceeds VBR, limiting downstream voltage to ≤243 V at 2.5 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
The SMBJ150CHE3/5B is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and supports peak forward surge current (IFSM) up to 100 A (8.3 ms half-sine). Its MSL Level 1 rating (JEDEC J-STD-020) and 260 °C lead-free reflow compatibility confirm suitability for high-reliability automated manufacturing.
Key Specifications
| Parameter | Value and Actual 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 |
|---|---|---|---|
| SMBJ150AHE3/5B | Same electrical specs and AEC-Q101 qualification; differs only in packaging suffix notation (HE3 vs HE3/5B denotes same reel size and tape configuration) | No functional difference; identical use in automotive and industrial designs | Select SMBJ150AHE3/5B only if internal procurement systems require explicit "A" suffix for unidirectional variants |
| SMCJ150A-E3/57 | Higher 1500 W PPPM, larger SMC (DO-214AB) package, same VWM/VC ratings but 3× higher IPPM (5.0 A) | Better suited for high-energy surges (e.g., outdoor telecom cabinets); requires larger PCB footprint and thermal pad area | Choose SMCJ150A-E3/57 when surge threat level exceeds 600 W or when design allows SMC footprint and enhanced thermal margin |
Compared with SMBJ150AHE3/5B, the SMBJ150CHE3/5B is functionally identical; versus SMCJ150A-E3/57, it trades surge capacity for compact SMB layout and lower cost - optimal for space-constrained 24–48 V industrial controls where 600 W protection suffices.

FAQ
What is the clamping voltage of SMBJ150CHE3/5B at its rated peak pulse current?
The SMBJ150CHE3/5B has a maximum clamping voltage (VC) of 243 V at IPPM = 2.5 A 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 a surge event. The SMBJ150CHE3/5B maintains this clamping performance across its full operating temperature range (−55 °C to +150 °C) and is validated per JEDEC standards.
Is SMBJ150CHE3/5B suitable for automotive applications?
Yes, SMBJ150CHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements. The SMBJ150CHE3/5B is deployed in body control modules, lighting drivers, and infotainment power rails where robust transient immunity and long-term reliability are mandated.
What does the "HE3/5B" suffix mean in SMBJ150CHE3/5B?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification; "5B" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format ensures compatibility with high-speed pick-and-place equipment and supports JIT manufacturing. The SMBJ150CHE3/5B meets JESD201 Class 2 whisker resistance and J-STD-002 solderability standards.
How does SMBJ150CHE3/5B differ from bidirectional SMBJ150C variants?
The SMBJ150CHE3/5B is unidirectional, featuring a cathode band and conducting only in reverse bias - ideal for DC rail protection. Bidirectional variants (e.g., SMBJ150CHC3/5B) suppress surges in both polarities and lack polarity marking. The SMBJ150CHE3/5B offers lower leakage at VWM and is preferred for asymmetric voltage domains; bidirectional types suit AC-coupled or floating signal lines.
What PCB layout guidance applies to SMBJ150CHE3/5B for optimal thermal performance?
For rated 600 W pulse handling, Vishay specifies 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, connected to internal ground/power planes via multiple thermal vias. Trace width should be ≥20 mils; minimize trace length between SMBJ150CHE3/5B and protected node. The SMBJ150CHE3/5B's RθJL = 20 °C/W assumes this layout - reducing pad size increases junction temperature and degrades surge endurance.
