Product details
Overview
SMBJ150AHE3_A/I 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, 243 V maximum clamping voltage (VC) at 2.5 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - deployed on ICs, MOSFETs, and sensor signal lines in industrial and telecom systems.
For engineers reviewing the SMBJ150AHE3_A/I datasheet, SMBJ150AHE3_A/I pinout, SMBJ150AHE3_A/I application, or SMBJ150AHE3_A/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance data, clamping performance under surge conditions, and real-world protection use cases for high-reliability embedded power and interface circuits.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction for stable avalanche behavior. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) and 20 °C/W junction-to-lead (RθJL) support operation up to +150 °C junction temperature under defined PCB pad layouts.
The SMBJ150AHE3_A/I meets MSL level 1 per J-STD-020, with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, and is qualified to AEC-Q101 for automotive applications - confirmed by HE3 suffix and revision code "A" in the ordering nomenclature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 150 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 167–185 V at 1 mA - guaranteed avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 243 V at IPPM = 2.5 A - peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity under standardized 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 surges |
| ID (Reverse Leakage) | 1.0 μA max at VWM - ultra-low standby current preserves system efficiency and avoids false triggering |
| TJ max. | +150 °C - maximum junction temperature rating; supports operation in harsh environments including engine bays and industrial enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, humidity testing, and surge endurance |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150AHM3_A/I | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification | Required where halogen-free material compliance is mandated (e.g., EU automotive Tier 1 supply chains) | Select when environmental compliance exceeds baseline RoHS requirements |
| SMCJ150AHE3_A/I | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package with 1500 W PPPM rating | Used where higher surge energy handling (>600 W) or improved thermal dissipation is needed | Choose only if board space permits larger footprint and 1500 W capability is required |
Compared with SMBJ150AHE3_A/I, the HM3 variant adds halogen-free construction without trade-offs in performance or qualification, while the SMCJ150AHE3_A/I offers 2.5× higher pulse power in a physically larger package - making SMBJ150AHE3_A/I optimal for space-constrained, AEC-Q101–compliant 600 W protection.

FAQ
What is the clamping voltage of SMBJ150AHE3_A/I at its rated peak pulse current?
The SMBJ150AHE3_A/I has a maximum clamping voltage (VC) of 243 V at a peak pulse current (IPPM) of 2.5 A under the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and represents the upper voltage limit imposed on protected circuitry during a standardized surge event - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMBJ150AHE3_A/I qualified for automotive applications?
Yes, SMBJ150AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and revision code "A" in its full part number. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance per automotive reliability standards - making it suitable for body electronics, infotainment, and ADAS subsystems where field failure is unacceptable.
What does the "A/I" suffix indicate in SMBJ150AHE3_A/I?
The "A/I" suffix in SMBJ150AHE3_A/I specifies packaging and reel configuration: "A" denotes revision level A per Vishay's document control, and "I" indicates 13-inch diameter plastic tape-and-reel delivery with 3200 units per reel. This format supports high-volume automated SMT placement and aligns with IPC-7351B land pattern recommendations for SMB (DO-214AA).
How does SMBJ150AHE3_A/I differ from bidirectional variants like SMBJ150CA?
SMBJ150AHE3_A/I is unidirectional with cathode-band polarity and specified for clamping only in reverse bias, whereas SMBJ150CA is bidirectional with symmetrical breakdown in both directions and no polarity marking. The unidirectional SMBJ150AHE3_A/I provides lower leakage (<1 μA at VWM) and is preferred for DC-coupled lines like power rails or single-ended signals where polarity is fixed.
What thermal derating applies to SMBJ150AHE3_A/I above 25 °C ambient?
SMBJ150AHE3_A/I follows Vishay's standard derating curve: peak pulse power decreases linearly above TA = 25 °C, reaching ~50 % of 600 W at +100 °C ambient when mounted on minimum recommended 0.2" × 0.2" copper pads. Its RθJA of 100 °C/W means junction temperature rises ~25 °C per watt of sustained power dissipation - critical for sustained surge repetition rate planning.
