Product details
Overview
P6SMB180CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, 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). It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the P6SMB180CAHE3_B/I datasheet, P6SMB180CAHE3_B/I pinout, P6SMB180CAHE3_B/I application, or P6SMB180CAHE3_B/I equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal resistance data, and validated alternative parts for ESD and lightning transient suppression in industrial and automotive systems.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
The device uses a DO-214AA (SMB) package with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102, rated for MSL Level 1 (260 °C reflow peak), and achieves 100 °C/W junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 171–189 V at IT = 1 mA - Voltage at which device transitions into avalanche conduction; tight tolerance supports predictable protection onset. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capability under standardized surge waveform; enables robust protection against repetitive transients. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Minimal standby current ensures negligible power loss and no interference with high-impedance signal paths. |
| TJ max. | +150 °C - Maximum junction temperature rating allows reliable operation in under-hood automotive environments. |
| RθJA | 100 °C/W - Thermal resistance value used to calculate junction temperature rise under DC or low-duty-cycle surge conditions. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode band absent per bidirectional design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity surge) | Conducts during negative-going transients; forms symmetrical clamping path with cathode terminal. |
| Cathode | Transient current entry (positive polarity surge) | Conducts during positive-going transients; paired with anode to enable full-wave surge suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring reliability over temperature and lifetime. |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity without derating in standard PCB layouts. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage stress on protected ICs-critical for 3.3 V or 5 V logic interfacing with 12 V/24 V supply domains. |
| MSL Level 1 moisture sensitivity | Enables direct placement into standard SMT reflow profiles (peak 260 °C) without baking or special handling. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure in industrial environments. |

Use Value: Limits VBUS overshoot to <250 V during ±8 kV contact ESD (IEC 61000-4-2), preserving port functionality after repeated discharges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180CA | Same VWM (154 V), lower PPPM (400 W), higher RθJA (150 °C/W), non-AEC-Q101 | Limited to commercial-grade industrial equipment; not suitable for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary. |
| SMCJ180CA | Same VWM (154 V), higher PPPM (1500 W), larger SMC (DO-214AB) package, AEC-Q101 available (HE3 suffix) | Requires PCB area increase (~30% larger footprint); suited for high-energy surge zones like power entry | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger package. |
Compared with SMAJ180CA and SMCJ180CA, the P6SMB180CAHE3_B/I offers optimal balance of AEC-Q101 compliance, 600 W surge capacity, and SMB footprint-making it ideal for space-constrained automotive modules where qualification and moderate energy handling are jointly required.

FAQ
What is the clamping voltage of P6SMB180CAHE3_B/I at its rated peak pulse current?
The P6SMB180CAHE3_B/I has a maximum clamping voltage (VC) of 246 V when subjected to its specified peak pulse current (IPPM) 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 circuits during surge events. The P6SMB180CAHE3_B/I maintains this clamping performance across its qualified temperature range (−65 °C to +150 °C) and is validated for repetitive surge duty cycles up to 0.01 %.
Is P6SMB180CAHE3_B/I suitable for automotive applications?
Yes, the P6SMB180CAHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" and "_B" suffixes in its ordering code. It meets stress test requirements for temperature cycling, humidity bias, mechanical shock, and surge robustness required for automotive electronic control units. The P6SMB180CAHE3_B/I is commonly deployed in engine management sensors, body control modules, and ADAS camera interfaces where bidirectional transient suppression and long-term reliability are mandatory.
How does the bidirectional configuration of P6SMB180CAHE3_B/I affect its circuit implementation?
The bidirectional configuration of P6SMB180CAHE3_B/I means it provides symmetrical clamping for both positive and negative voltage transients without polarity sensitivity-no cathode marking is present. This allows direct placement across differential lines (e.g., CAN_H/CAN_L) or ungrounded signal pairs. Unlike unidirectional TVS diodes, the P6SMB180CAHE3_B/I eliminates the need for orientation verification during assembly and simplifies layout for AC-coupled or floating interfaces.
What is the thermal resistance of P6SMB180CAHE3_B/I, and how does it impact PCB layout?
The P6SMB180CAHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 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 adhere to this pad size minimum. Reducing pad area increases RθJA and risks thermal runaway; adding thermal vias or copper pours improves heat dissipation but does not change the baseline RθJA rating unless explicitly characterized in Vishay's thermal models.
Does P6SMB180CAHE3_B/I meet RoHS and halogen-free requirements?
Yes, the P6SMB180CAHE3_B/I carries the "HE3" suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. Per Vishay documentation, HE3 parts use lead-free matte tin plating and comply with JEDEC J-STD-020 MSL Level 1. While not explicitly labeled "halogen-free", the base P/NHE3 designation aligns with Vishay's commercial-grade RoHS-compliant materials; halogen-free versions require the "HM3" suffix (e.g., P6SMB180CAHM3_B/I), which is a distinct ordering option.
