Product details
Overview
P6SMB160CAHE3_B/H 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 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB160CAHE3_B/H datasheet, P6SMB160CAHE3_B/H pinout, P6SMB160CAHE3_B/H application, or P6SMB160CAHE3_B/H equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, AEC-Q101 qualification, and SMB (DO-214AA) package compatibility are required in space-constrained PCB layouts.
Technical Context
The P6SMB160CAHE3_B/H operates as a bidirectional avalanche diode, symmetrically clamping transient voltages above ±179 V (VBR min) and limiting peak reverse voltage to ≤219 V (VC) under 2.7 A IPPM. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
Designed for automated SMT assembly, it meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and delivers 600 W transient suppression capability with <1 ns response time - critical for protecting sensitive inputs against inductive switching spikes and lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working range. |
| VBR (Breakdown Voltage) | 152–168 V at 1.0 mA IT - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 219 V at 2.7 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress margin for downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity for standardized 10/1000 μs waveform; enables single-event surge compliance per IEC 61000-4-5. |
| ID (Reverse Leakage) | ≤1.0 μA at 136 V - Minimal standby current; avoids signal distortion or battery drain in always-on circuits. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. No polarity marking - bidirectional symmetry eliminates orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical terminals; conducts equally in both directions above VBR - no anode/cathode distinction required in layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines without polarity constraints. |
| 600 W peak pulse power | Meets IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out with recommended 5.0 mm × 5.0 mm copper pads. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring long-term field reliability. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow profile use - eliminates baking requirements prior to assembly. |
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime, with minimal parameter drift versus silicon-junction alternatives. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM (136 V), identical SMB package, but rated for 600 W with tighter VC tolerance (219 V vs. 220 V); not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial designs where AEC validation is not mandated. | Select SMBJ160CA when cost sensitivity outweighs automotive compliance and full AEC-Q101 traceability is unnecessary. |
| 1.5SMC160CA | Higher package thermal resistance (RθJA = 125 °C/W vs. 100 °C/W); same electrical specs but larger SMC (DO-214AB) footprint. | Requires PCB area increase (~30% larger pad layout); less suitable for dense automotive modules. | Choose 1.5SMC160CA only if existing design uses SMC footprint and thermal derating margins allow higher RθJA. |
Compared with SMBJ160CA and 1.5SMC160CA, P6SMB160CAHE3_B/H uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and verified 100 °C/W thermal resistance - making it the preferred choice for new automotive and space-constrained industrial designs requiring production-grade reliability.

FAQ
What is the clamping voltage of P6SMB160CAHE3_B/H at its rated peak pulse current?
The P6SMB160CAHE3_B/H has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM) under the standard 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. The P6SMB160CAHE3_B/H maintains this clamping performance across its specified operating temperature range.
Is P6SMB160CAHE3_B/H suitable for automotive applications?
Yes, P6SMB160CAHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3_B", which denotes RoHS-compliant and AEC-Q101 validated construction. It undergoes stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D. The P6SMB160CAHE3_B/H is approved for use in engine control units, body electronics, and ADAS sensors where automotive-grade reliability is mandatory.
What does the "CA" suffix indicate in P6SMB160CAHE3_B/H?
The "CA" suffix in P6SMB160CAHE3_B/H specifies a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics for positive and negative surges. This eliminates the need for polarity-aware placement and makes the P6SMB160CAHE3_B/H ideal for AC signal lines, differential buses, and ungrounded power rails.
What is the thermal resistance of P6SMB160CAHE3_B/H, and how does it affect layout?
The P6SMB160CAHE3_B/H 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, as defined in Vishay Document 88370. This value assumes minimum recommended pad layout; reducing pad size increases thermal resistance and requires derating of PPPM. For reliable 600 W surge handling, the P6SMB160CAHE3_B/H must be placed using the specified copper area to avoid thermal runaway during repetitive transients.
How does P6SMB160CAHE3_B/H compare to unidirectional variants like P6SMB160AHE3_B/H?
Unlike unidirectional P6SMB160AHE3_B/H, the P6SMB160CAHE3_B/H provides equal clamping in both directions and lacks cathode band marking - simplifying layout and enabling protection of floating or AC-coupled nodes. Unidirectional versions conduct only in reverse bias and require correct polarity alignment; the P6SMB160CAHE3_B/H avoids misorientation risk and supports dual-rail or differential signaling where polarity reversal may occur.
