Product details
Overview
P6SMB160CAHE3_A/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 and 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 in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB160CAHE3_A/I datasheet, P6SMB160CAHE3_A/I pinout, P6SMB160CAHE3_A/I application, or P6SMB160CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and verified 150 °C junction temperature rating for under-hood automotive environments.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting sensitive analog front-ends and CAN/LIN bus receivers against ESD and load-dump events.
The device is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits low incremental surge resistance, enabling effective energy diversion during repetitive 0.01% duty-cycle transients. Thermal resistance (RθJA = 100 °C/W) and RθJL = 20 °C/W support reliable operation on standard 0.2" × 0.2" copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 152–168 V at 1.0 mA test current - Ensures predictable turn-on threshold with tight 5% tolerance. |
| VC (Clamping Voltage) | 219 V at 2.7 A IPPM - Limits transient voltage seen by downstream ICs to safe levels during 10/1000 μs surges. |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients per IEEE C62.41 without degradation when mounted per recommended pad layout. |
| TJ max. | 150 °C - Enables use in under-hood automotive modules and industrial controllers with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated placement; meets UL 94 V-0 flammability. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode band not marked (bidirectional type).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no polarity marking required - enables flexible PCB routing in differential or single-ended lines. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160CA | Same VWM (136 V) and VC (219 V), but lower PPPM (400 W); SMA package (DO-214AC), larger footprint than SMB. | Limited to lower-energy transients; less suitable for ISO 7637-2 Pulse 5a compliance in automotive. | Select when board space allows larger package and surge energy requirements are ≤400 W. |
| 1.5KE160CA | Higher PPPM (1500 W), axial-leaded DO-15 package; significantly slower response (>5 ns) and higher capacitance. | Not suitable for high-speed data lines or automated SMT assembly; requires through-hole mounting. | Choose only for legacy through-hole designs where peak power exceeds 600 W and layout permits axial components. |
Compared with SMAJ160CA and 1.5KE160CA, P6SMB160CAHE3_A/I delivers optimal balance of 600 W surge handling, SMB footprint efficiency, sub-ns response, and AEC-Q101 qualification - making it the preferred choice for new automotive and industrial SMT designs requiring compact, qualified TVS protection.

FAQ
What does the "CA" suffix indicate in P6SMB160CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB160CAHE3_A/I provides symmetrical clamping for both positive and negative voltage transients without polarity sensitivity. This distinguishes it from unidirectional variants (e.g., P6SMB160A) and makes it ideal for AC-coupled or floating signal paths such as RS-485, CAN bus, or bridge sensor outputs where voltage polarity may reverse.
Is P6SMB160CAHE3_A/I qualified for automotive applications?
Yes, P6SMB160CAHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It has undergone stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD22-A114, making it suitable for under-hood and chassis-mounted automotive electronics such as engine control sensors, body control modules, and ADAS camera interfaces.
What is the maximum clamping voltage of P6SMB160CAHE3_A/I and at what current is it specified?
The maximum clamping voltage (VC) of P6SMB160CAHE3_A/I is 219 V, measured at a peak pulse current (IPPM) of 2.7 A using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMB (DO-214AA) package of P6SMB160CAHE3_A/I compare to SMA (DO-214AC) in terms of board space and thermal performance?
The SMB package of P6SMB160CAHE3_A/I measures 3.94 mm × 2.20 mm - approximately 30% smaller in footprint than the SMA (DO-214AC) package. While both share similar thermal resistance (RθJA ≈ 100 °C/W), SMB's reduced size enables denser layouts in space-constrained applications like automotive ECUs and portable industrial tools, without sacrificing surge capability.
Can P6SMB160CAHE3_A/I be used in place of a unidirectional TVS like P6SMB160A?
No - P6SMB160CAHE3_A/I is bidirectional and lacks polarity marking, whereas P6SMB160A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: P6SMB160CAHE3_A/I is appropriate for AC or floating lines, but cannot replace P6SMB160A in DC-biased applications where forward conduction must be blocked in one direction. Always validate clamping symmetry and leakage behavior in the target design.
