Product details
Overview
P6SMB180CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 154 V standoff 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 (10/1000 μs waveform), used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB180CAHE3_B/H datasheet, P6SMB180CAHE3_B/H pinout, P6SMB180CAHE3_B/H application, or P6SMB180CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT assembly on PCBs requiring IEC 61000-4-2/4-5 level protection.
Technical Context
The P6SMB180CAHE3_B/H operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the SMB package provides low thermal resistance (RθJL = 20 °C/W) and meets MSL Level 1 reflow requirements (260 °C peak).
It delivers 600 W peak pulse power under standardized 10/1000 μs waveform conditions with 0.01% duty cycle, and supports repetitive surge events when thermally managed per derating curves. The device exhibits a +0.108 %/°C temperature coefficient of VBR and ≤1.0 μA reverse leakage at VWM - critical for low-power sensor line protection where standby current must remain minimal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 154 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 171–189 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines downstream component stress. |
| PPPM | 600 W - Surge energy handling capacity under standard waveform; enables robust protection against lightning-induced surges and inductive switching spikes. |
| TJ max. | 150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and high-ambient industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; required for ECUs and ADAS sensor modules. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with standard 7" tape-and-reel SMT placement equipment. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 compliant. Bidirectional construction means no cathode/anode marking; terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Transient input node (bidirectional) | Connects to line under protection (e.g., CAN_H or RS-485 A); conducts surge current equally in either direction. |
| Terminal 2 | Transient return node (bidirectional) | Connects to reference plane (e.g., ground or signal common); completes low-inductance clamping path during ESD or surge event. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of differential or AC-coupled lines (e.g., CAN, RS-485, audio inputs) without polarity concerns. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) when mounted per recommended 5.0 mm × 5.0 mm copper pads. |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and infotainment systems requiring long-term field reliability. |
| Low profile SMB package | 0.220" × 0.130" footprint with 0.086" height enables dense PCB layouts and compatibility with automated pick-and-place systems. |
| Fast response time | <1 ns turn-on ensures clamping occurs before sensitive ICs (e.g., microcontrollers, transceivers) experience damaging overvoltage. |
Applications
| Automotive Sensor Interface Protection | Industrial RS-485 Communication Line |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | Same VWM (154 V), identical SMB package, but not AEC-Q101 qualified; higher VC (252 V at 2.4 A). | Targeted at commercial/industrial use only; unsuitable for automotive OEM designs requiring AEC-Q101 documentation. | Select when AEC-Q101 is not mandated and cost sensitivity outweighs qualification traceability. |
| 1.5SMC180CA | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs; not AEC-Q101 qualified. | Used where higher surge margin is needed (e.g., outdoor telecom cabinets), but requires PCB layout change due to 7.11 mm × 6.22 mm footprint. | Choose when system-level surge test levels exceed IEC 61000-4-5 Level 4 and board space allows larger package. |
Compared with SMBJ180CA and 1.5SMC180CA, P6SMB180CAHE3_B/H uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W rating - making it the only drop-in solution for automotive Tier-1 suppliers needing validated reliability without redesigning layout or qualifying new components.

FAQ
What is the clamping voltage of P6SMB180CAHE3_B/H at its rated peak pulse current?
The P6SMB180CAHE3_B/H has a maximum clamping voltage (VC) of 246 V at 2.4 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value is confirmed in the Vishay datasheet (Document Number: 88370, Revision: 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB180CAHE3_B/H maintains this clamping performance across its specified operating temperature range (-65 °C to +150 °C), with minimal drift due to its +0.108 %/°C VBR temperature coefficient.
Is P6SMB180CAHE3_B/H suitable for automotive applications?
Yes, P6SMB180CAHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use, as indicated by the "HE3" suffix and "_B" revision code in the ordering part number. It has undergone stress testing per AEC-Q101 standards including temperature cycling, high-temperature reverse bias (HTRB), and ESD (HBM/MM). The P6SMB180CAHE3_B/H is deployed in engine control modules, ADAS camera interfaces, and body control units where sustained reliability under thermal and electrical stress is mandatory.
How does the bidirectional design of P6SMB180CAHE3_B/H affect its circuit implementation?
The bidirectional design of P6SMB180CAHE3_B/H eliminates polarity marking and allows symmetric placement across differential or AC-coupled signal paths - such as CAN bus lines, RS-485 A/B, or audio inputs - without concern for orientation. Unlike unidirectional TVS diodes, the P6SMB180CAHE3_B/H clamps both positive and negative transients identically, simplifying layout and reducing BOM count. Its terminals are electrically interchangeable, and no cathode band is present on the SMB package.
What is the thermal resistance of P6SMB180CAHE3_B/H, and how does it impact PCB layout?
The P6SMB180CAHE3_B/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures during repetitive surges, PCB layout must replicate these pad dimensions and avoid excessive trace length or narrow connections. The P6SMB180CAHE3_B/H's low RθJL enables effective heat transfer to the PCB plane, supporting reliable operation at ambient temperatures up to +125 °C in enclosed industrial enclosures.
Does P6SMB180CAHE3_B/H meet RoHS and halogen-free requirements?
Yes, P6SMB180CAHE3_B/H is RoHS-compliant and halogen-free, as confirmed by the "HE3" base suffix and "_B/H" ordering code per Vishay's material categorization documentation (www.vishay.com/doc?99912). It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and complies with JEDEC JS-001 ESD classification. The P6SMB180CAHE3_B/H also satisfies JESD201 Class 2 whisker resistance requirements for matte tin-plated terminations.
