Product details
Overview
P6SMB180AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 154 V stand-off voltage (VWM), 171–189 V breakdown voltage (VBR) at 1 mA, 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P6SMB180AHE3/52 datasheet, P6SMB180AHE3/52 pinout, P6SMB180AHE3/52 application, or P6SMB180AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–65 to +150 °C), and compliance with J-STD-020 MSL level 1 reflow profile.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR), diverting transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the low incremental surge resistance enables effective suppression of high-energy transients induced by inductive switching or ESD events.
The P6SMB180AHE3/52 is rated for 600 W peak pulse power under 10/1000 μs waveform conditions with 0.01% duty cycle, and supports repetitive surge handling when thermally managed per derating curves. Its unidirectional configuration requires correct cathode orientation (marked band), and it meets RoHS compliance with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 154 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 171–189 V at IT = 1 mA - Voltage at which device enters controlled avalanche; tight tolerance ensures predictable turn-on behavior. |
| VC (Clamping) | 246 V at IPPM = 2.4 A - Peak voltage seen across protected circuit during 10/1000 μs transient; determines stress on downstream components. |
| PPPM | 600 W - Peak transient energy absorption capacity under standardized waveform; validates suitability for IEC 61000-4-5 Level 3/4 surges. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad sizing (0.2" × 0.2") for reliable power dissipation. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per AEC standard. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads. Cathode indicated by a band on the body; anode is unmarked end. Meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage event. |
| Anode (unmarked end) | Reference node | Typically tied to system ground or lower-potential rail; completes current path during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Supports robust protection against lightning-induced surges and load dump transients in 12 V/24 V systems. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive electronics including engine control units, ADAS sensors, and infotainment power rails. |
| Glass passivated junction | Ensures stable reverse leakage (<1 μA at VWM) and long-term reliability under thermal cycling and humidity stress. |
| MSL level 1 (260 °C peak) | Enables standard SMT reflow without moisture sensitivity concerns; eliminates pre-bake requirement. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage exposure to protected ICs - critical for 16-bit ADCs, CAN transceivers, and microcontrollers. |
Applications
| Automotive Sensor Protection | Industrial Power Supply Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A-E3/52 | Same VWM (154 V), VC (246 V), and PPPM (600 W); SMA package (DO-214AC), higher RθJA (140 °C/W). | Lower power density; less suitable for high-temperature automotive under-hood use without enhanced heatsinking. | Select if legacy SMA footprint compatibility required; verify thermal margin with 0.1"² copper pads. |
| 1.5SMC180A | Same electrical specs but SMC (DO-214AB) package; larger body, RθJA = 65 °C/W, higher IFSM (200 A). | Better thermal performance and surge endurance; incompatible with SMB land pattern due to 0.220" width vs. 0.180". | Choose for industrial designs needing higher single-pulse robustness and relaxed thermal constraints. |
Compared with SMAJ180A-E3/52, P6SMB180AHE3/52 offers superior thermal performance in confined spaces; versus 1.5SMC180A, it provides identical protection in a 30% smaller footprint but requires tighter layout control for thermal management.

FAQ
What is the maximum clamping voltage of the P6SMB180AHE3/52 under a 10/1000 μs transient?
The P6SMB180AHE3/52 has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current of 2.4 A under a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6SMB180AHE3/52 qualified for automotive applications?
Yes, the P6SMB180AHE3/52 is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code and documented in Vishay's P6SMB series specification (Rev. 09-Jan-2024). This qualification covers temperature cycling, high-temperature reverse bias, and mechanical shock testing - making P6SMB180AHE3/52 suitable for engine control modules, body electronics, and ADAS sensor interfaces.
What does the "HE3" suffix indicate in P6SMB180AHE3/52?
The "HE3" suffix in P6SMB180AHE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability standards. It distinguishes this automotive-grade variant from commercial "E3" versions and confirms compliance with JESD 201 Class 2 whisker resistance - essential for long-life deployments in vibration-prone environments.
Can P6SMB180AHE3/52 be used in bidirectional protection circuits?
No, P6SMB180AHE3/52 is a unidirectional TVS diode, identifiable by its cathode band marking and specified electrical characteristics only for reverse-biased operation. For bidirectional protection, Vishay specifies part numbers ending in "CA" (e.g., P6SMB180CA); using P6SMB180AHE3/52 in AC-coupled or symmetrical surge paths would result in forward conduction failure during positive half-cycles.
What is the thermal resistance junction-to-ambient for P6SMB180AHE3/52?
The P6SMB180AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air conditions and directly impacts sustained surge repetition rate - designers must apply derating above 25 °C ambient per Figure 2 in the Vishay datasheet to avoid thermal runaway.
