Product details
Overview
SMBJ150HE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 150 V stand-off voltage (VWM), 167–185 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 243 V at 2.5 A IPPM, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the SMBJ150HE3/52 datasheet, SMBJ150HE3/52 pinout, SMBJ150HE3/52 application, or SMBJ150HE3/52 equivalent, this device is selected for robust overvoltage protection on DC power rails, MOSFET gate drivers, and sensor signal lines where high clamping efficiency, low leakage (<1.0 µA at VWM), and automotive-grade reliability are required.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp with glass-passivated junction, enabling fast response time (<1.0 ns) and low incremental surge resistance. Its thermal resistance (RθJA = 100 °C/W) and junction temperature range (–55 °C to +150 °C) support operation in harsh environments including under-hood automotive systems and industrial motor controls.
The device complies with UL 497B recognition (QVGQ2) and meets J-STD-020 MSL Level 1 (260 °C peak reflow). Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing - confirming suitability for automated SMT assembly and long-term field reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 150 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12–48 V systems. |
| VBR (Breakdown Voltage) | 167–185 V at IT = 1 mA - precise avalanche onset threshold ensuring predictable turn-on during transients. |
| VC (Clamping Voltage) | 243 V at IPPM = 2.5 A - limits peak voltage seen by protected ICs during 10/1000 µs surge, preserving downstream components. |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized 10/1000 µs waveform; enables protection against IEC 61000-4-5 Level 3 surges. |
| ID (Reverse Leakage) | ≤1.0 µA at VWM - negligible standby current draw, critical for low-power sensor nodes and battery-backed circuits. |
| TJ max. | +150 °C - supports operation in high-temperature automotive and industrial enclosures without derating. |
| AEC-Q101 Qualified | Yes - validated for automotive electronic modules requiring stress-tested reliability across temperature cycling, HTRB, and ESD. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-E3/52 | Commercial-grade version; lacks AEC-Q101 qualification and has higher MSL level (not specified as MSL 1). | Approved for industrial/commercial use only; not certified for automotive production. | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive qualification. |
| SMCJ150AHE3/A | Larger SMC (DO-214AB) package; same electrical specs but higher thermal mass (RθJA = 40 °C/W vs. 100 °C/W). | Better suited for high-duty-cycle surge environments where SMBJ150HE3/52 may thermally saturate. | Choose when board space allows and sustained surge repetition (>0.01% duty cycle) is expected. |
Compared with SMBJ150A-E3/52, SMBJ150HE3/52 adds automotive qualification and tighter process control; compared with SMCJ150AHE3/A, it trades thermal performance for compact SMB footprint - making it optimal for space-constrained automotive ECUs and portable medical devices.

FAQ
What is the clamping voltage of SMBJ150HE3/52 at its rated peak pulse current?
The SMBJ150HE3/52 has a maximum clamping voltage (VC) of 243 V at a peak pulse current (IPPM) of 2.5 A using the 10/1000 µs waveform. This value is measured under standard test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ150HE3/52 maintains this clamping performance while sustaining 600 W peak pulse power, making it suitable for IEC 61000-4-5 compliance testing.
Is SMBJ150HE3/52 qualified for automotive applications?
Yes, SMBJ150HE3/52 is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM ≥ 8 kV), validating its use in automotive electronic control units such as body control modules and ADAS power domains. The SMBJ150HE3/52 is explicitly designated for automotive production in Vishay's ordering information table.
What is the standoff voltage (VWM) and why does it matter for SMBJ150HE3/52?
The standoff voltage (VWM) of SMBJ150HE3/52 is 150 V - the maximum DC or continuous reverse voltage the device can withstand without entering conduction. This parameter ensures the SMBJ150HE3/52 remains non-conductive during normal operation, minimizing leakage current (<1.0 µA) and avoiding unnecessary power loss or interference. Selecting VWM ≥ 1.1× system nominal voltage prevents false triggering while retaining sufficient margin for ripple and tolerance.
How does the SMBJ150HE3/52 package compare to SMCJ variants in terms of thermal performance?
The SMBJ150HE3/52 uses the SMB (DO-214AA) package with a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, whereas SMCJ-series equivalents use the larger SMC (DO-214AB) package with RθJA ≈ 40 °C/W. This means the SMBJ150HE3/52 dissipates heat less efficiently under sustained surge conditions. For applications involving repetitive transients or elevated ambient temperatures, thermal derating must be applied per Figure 2 in the Vishay datasheet - unlike the SMCJ version, which better handles thermal accumulation.
Can SMBJ150HE3/52 be used in bidirectional configurations?
No, SMBJ150HE3/52 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., SMBJ150CA). Using SMBJ150HE3/52 in reverse-biased AC or floating-signal applications would result in forward conduction and potential failure. For bidirectional protection at 150 V, specify SMBJ150CAHE3/52 - which exhibits symmetrical clamping in both directions and no polarity marking.
