Product details
Overview
P6SMB180CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 180 V standoff voltage (VWM), 207 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤246 V at 2.4 A peak pulse current and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB180CAHM3_B/H datasheet, P6SMB180CAHM3_B/H pinout, P6SMB180CAHM3_B/H application, or P6SMB180CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, 150 °C max junction temperature, MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on PCBs requiring robust ESD and surge immunity per IEC 61000-4-2/4-5.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative polarity transients without polarity-sensitive placement. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting sensitive analog and digital inputs against inductive switching spikes and lightning-induced surges.
The device uses a low-inductance SMB (DO-214AA) package with matte tin-plated leads solderable per J-STD-002, delivering 20 °C/W junction-to-lead thermal resistance. Derating begins above 25 °C ambient, with full 600 W pulse rating only at TA = 25 °C and mounted on 5.0 mm × 5.0 mm copper pads per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 180 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for 180 V nominal bus lines. |
| VBR (Breakdown Voltage) | 207–231 V at 1 mA - Voltage at which device enters avalanche conduction; ensures reliable triggering above normal operating voltage. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines maximum stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capacity under standardized 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 compliance when properly laid out. |
| ID (Reverse Leakage) | ≤1.0 μA at 180 V - Minimal standby current draw; avoids loading of high-impedance signal paths or battery-powered circuits. |
| TJ max. | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| Package | SMB (DO-214AA) - Industry-standard surface-mount outline with 0.220" x 0.205" footprint; compatible with standard pick-and-place and reflow profiles. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Case dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for J-STD-002-compliant solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; bidirectional clamping occurs regardless of voltage polarity applied across the device. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional transient suppression | Enables single-device protection of AC-coupled or differential signal lines without polarity orientation constraints. |
| 600 W peak pulse power (10/1000 μs) | Supports robust immunity against severe surges including indirect lightning strikes and relay coil flyback in automotive ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | Same VWM (180 V), identical SMB package, but rated for 600 W with tighter VBR tolerance (207–220 V vs. 207–231 V); non-AEC-Q101, commercial-grade only. | Lacks automotive qualification and halogen-free certification; unsuitable for OEM automotive BOMs requiring PPAP documentation. | Select SMBJ180CA only for cost-sensitive industrial or consumer designs where AEC-Q101 and HM3 material compliance are not required. |
| 1.5SMC180CA | Higher power rating (1500 W), larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); same VWM and bidirectional functionality. | Requires PCB layout revision due to 2.5× larger footprint and higher thermal mass; better suited for high-energy surge zones like AC mains entry. | Choose 1.5SMC180CA when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger package. |
Compared with SMBJ180CA and 1.5SMC180CA, P6SMB180CAHM3_B/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint-enabling drop-in replacement in automotive signal-line protection without compromising reliability or regulatory compliance.

FAQ
What is the clamping voltage of P6SMB180CAHM3_B/H at its rated peak pulse current?
The P6SMB180CAHM3_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 defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet Document Number 88370, page 2, Electrical Characteristics table for P6SMB180A.
Is P6SMB180CAHM3_B/H suitable for automotive applications?
Yes, P6SMB180CAHM3_B/H is AEC-Q101 qualified, halogen-free, and RoHS-compliant-meeting stringent automotive reliability requirements for under-hood and body electronics. The "HM3" suffix denotes halogen-free construction, and "_B/H" indicates AEC-Q101 qualification with 7" tape-and-reel packaging, making P6SMB180CAHM3_B/H appropriate for Tier-1 automotive supply chains.
What does the "CA" suffix mean in P6SMB180CAHM3_B/H?
The "CA" suffix in P6SMB180CAHM3_B/H designates a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB180A), P6SMB180CAHM3_B/H has no cathode marking and functions identically regardless of polarity-ideal for AC signal lines and differential buses like CAN or RS-485.
What is the maximum operating temperature for P6SMB180CAHM3_B/H?
The P6SMB180CAHM3_B/H has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of –65 °C to +150 °C. This rating allows reliable operation in under-hood automotive environments and industrial enclosures where ambient temperatures exceed 105 °C, provided PCB thermal design meets the recommended 5.0 mm × 5.0 mm copper pad layout.
How does the SMB package of P6SMB180CAHM3_B/H compare to SMC or SMA packages?
The SMB (DO-214AA) package of P6SMB180CAHM3_B/H measures 4.57 mm × 3.94 mm × 2.20 mm-smaller than SMC (DO-214AB) and larger than SMA (DO-214AC). It offers optimal balance between surge capability (600 W) and board space efficiency, with lower thermal resistance (RθJL = 20 °C/W) than SMA and better manufacturability than SMC in high-density layouts. P6SMB180CAHM3_B/H is not pin-compatible with SMC or SMA variants due to dimensional and pad-layout differences.
