Product details
Overview
P6SMB180AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 180 V standoff voltage (VWM), 246 V clamping voltage at 2.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and DC power rail protection.
For engineers reviewing the P6SMB180AHE3_A/I datasheet, P6SMB180AHE3_A/I pinout, P6SMB180AHE3_A/I application, or P6SMB180AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, SMB (DO-214AA) package thermal performance, and clamping behavior under repetitive surge conditions.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (171–189 V at 1 mA), it rapidly transitions to low-impedance conduction to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 μA at 154 V) and long-term reliability under thermal cycling.
The device is rated for 150 °C maximum junction temperature and exhibits 100 °C/W junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads. Its 20 °C/W junction-to-lead resistance supports localized heat dissipation during short-duration surges, and it meets J-STD-020 MSL Level 1 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 154 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin. |
| VBR (Breakdown) | 171–189 V at 1 mA - Voltage range where device initiates avalanche conduction; ensures predictable turn-on timing. |
| VC (Clamping) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability with standardized 10/1000 μs waveform; validates surge immunity per IEC 61000-4-5. |
| ID (Leakage) | <1.0 μA at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| TJ max. | 150 °C - Maximum junction temperature rating; enables operation in under-hood automotive and industrial ambient environments. |
| Package | SMB (DO-214AA) - Surface-mount outline with 0.220" × 0.130" footprint; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side of protected line; defines polarity-sensitive placement in series with load or across rail. |
| Cathode | Avalanche conduction node / Clamping output | Banded end; ties to higher-potential side (e.g., VBUS or signal line); conducts surge current to ground or return path during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces per stress test requirements. |
| Glass passivated junction | Ensures stable electrical parameters and long-term reliability under humidity, thermal cycling, and mechanical vibration. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surge events without degradation when mounted per recommended pad layout. |
| MSL Level 1 | Supports lead-free reflow up to 260 °C peak without moisture-induced failure; no baking required prior to assembly. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., inductive switch-off), improving protection margin. |
Applications
| Automotive Sensor Protection | Industrial DC Power Rail |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs.

Use Value: Maintains <10 pF junction capacitance at zero bias, avoiding signal distortion in 100BASE-TX and faster protocols. |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for smart home devices and USB PD accessories. IC Role / Device Role / Timing Role: Final-stage clamp on regulated 5 V/9 V/12 V output rails, triggered only during fault conditions. Use Value: Limits output voltage excursion to ≤246 V during open-regulator faults, preventing downstream component overstress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A-E3/5B | Same VWM (154 V) and VC (246 V), but SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-duty-cycle surges due to reduced thermal mass; unsuitable for automotive under-hood use above 105 °C ambient. | Select when board space is constrained and surge repetition rate is low; verify thermal margin with actual PCB copper area. |
| 1.5SMC180AHE3_A | Same electrical specs but SMC (DO-214AB) package: larger body, lower RθJA (80 °C/W), higher IFSM (200 A). | Better suited for high-energy industrial transients; requires larger PCB real estate and may not fit dense automotive layouts. | Choose for mission-critical 24 V systems needing extended surge endurance or higher forward surge tolerance. |
Compared with P6SMB180AHE3_A/I, SMAJ180A-E3/5B trades thermal robustness for compactness, while 1.5SMC180AHE3_A delivers superior power handling at the cost of footprint - making P6SMB180AHE3_A/I the balanced choice for AEC-Q101-compliant, space-constrained automotive and industrial designs.

FAQ
What is the breakdown voltage range for P6SMB180AHE3_A/I?
The P6SMB180AHE3_A/I has a specified breakdown voltage (VBR) range of 171 V to 189 V at a test current of 1 mA, measured per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation across production lots and temperature extremes, directly supporting its role as a precision clamping device in critical protection circuits.
Is P6SMB180AHE3_A/I qualified for automotive applications?
Yes, P6SMB180AHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - making it suitable for engine control, body electronics, and ADAS sensor protection.
What does the "_A/I" suffix mean in P6SMB180AHE3_A/I?
The "_A/I" suffix in P6SMB180AHE3_A/I indicates packaging configuration: "A" denotes the standard revision level per Vishay's internal coding, and "I" specifies 13-inch diameter plastic tape-and-reel delivery with 3200 units per reel - optimized for high-volume SMT assembly lines requiring traceable, moisture-safe handling.
How does P6SMB180AHE3_A/I compare to bidirectional variants like P6SMB180CA?
P6SMB180AHE3_A/I is unidirectional and intended for DC-biased lines where polarity is fixed, offering lower leakage and tighter VBR tolerance than bidirectional versions. In contrast, P6SMB180CA supports AC or floating signals but exhibits higher ID and wider VBR spread - so P6SMB180AHE3_A/I is preferred for 24 V power rail or sensor output protection.
What is the maximum clamping voltage of P6SMB180AHE3_A/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB180AHE3_A/I is 246 V at a peak pulse current (IPPM) of 2.4 A with a 10/1000 μs waveform. This value is guaranteed per datasheet Table "ELECTRICAL CHARACTERISTICS" and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
