Product details
Overview
P6SMB160CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features 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 signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB160CAHE3_A/H datasheet, P6SMB160CAHE3_A/H pinout, P6SMB160CAHE3_A/H application, or P6SMB160CAHE3_A/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 placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the low Rdyn minimizes voltage overshoot during transient events.
The device is rated for 600 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable operation in compact PCB layouts with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - precise voltage at which avalanche conduction initiates; ensures predictable turn-on across temperature |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - peak voltage seen by protected circuit during worst-case transient; determines stress on downstream components |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for 10/1000 μs surges; enables protection against IEC 61000-4-5 Level 4 surges |
| ID (Reverse Leakage) | 1.0 μA max at VWM - negligible standby current; avoids loading sensitive signal lines or battery-powered circuits |
| TJ max | 150 °C - maximum junction temperature; supports operation in under-hood automotive and industrial environments |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with J-STD-020 MSL level 1 |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, qualified to JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No functional distinction; either terminal serves as anode or cathode depending on transient polarity - enables single-device protection of AC or floating lines |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensors - meets stress-test requirements for temperature cycling, HTRB, and ESD |
| 600 W peak pulse power | Withstands high-energy transients such as load dump (ISO 7637-2) and EFT bursts (IEC 61000-4-4) without degradation |
| Glass passivated junction | Ensures long-term stability of VBR and leakage over temperature and lifetime; reduces parameter drift in harsh environments |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage exposure during clamping - critical for protecting 130–150 V-rated MOSFETs and gate drivers |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking; simplifies manufacturing integration |
Applications
| Automotive Sensor Signal Protection | Industrial PLC Analog Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Parallel-connected transient suppressor across rail and ground, sized for 600 W peak dissipation. Use Value: Absorbs up to 600 W for 1 ms, preventing overvoltage shutdown or MOSFET avalanche failure during relay de-energization. |
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), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for ISO 7637-2 load dump simulation | Select when board space is constrained and surge energy is <400 W |
| 1.5KE160CA | Same VWM and VC, but through-hole DO-201 package; higher thermal mass but incompatible with SMT assembly | Requires manual or wave-solder process; not suitable for high-density automated production | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMAJ160CA and 1.5KE160CA, P6SMB160CAHE3_A/H delivers higher surge robustness in an SMT-compatible package with AEC-Q101 qualification - making it the preferred choice for new automotive and industrial designs requiring production scalability and automotive-grade reliability.

FAQ
What does the "CA" suffix indicate in P6SMB160CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration - meaning the P6SMB160CAHE3_A/H conducts and clamps symmetrically in both polarities. Unlike unidirectional variants (e.g., P6SMB160A), it has no cathode band marking and protects AC-coupled or floating signal paths without polarity constraints. This makes P6SMB160CAHE3_A/H ideal for differential buses like RS-485 or transformer-isolated interfaces.
Is P6SMB160CAHE3_A/H suitable for automotive applications?
Yes, P6SMB160CAHE3_A/H is AEC-Q101 qualified (as indicated by the "HE3" suffix and "_A/H" ordering code), having passed stress tests including temperature cycling, high-temperature reverse bias, and ESD. It is specified for under-hood and chassis-mounted use up to 150 °C junction temperature, and commonly deployed in automotive body control modules, ADAS sensor hubs, and infotainment power supplies.
How does the clamping voltage of P6SMB160CAHE3_A/H compare to its breakdown voltage?
P6SMB160CAHE3_A/H has a minimum breakdown voltage (VBR) of 152 V and a maximum clamping voltage (VC) of 219 V at 2.7 A IPPM, yielding a clamping ratio of ~1.37. This tight ratio reflects low dynamic impedance and ensures protected circuits experience minimal overvoltage - critical for safeguarding 150 V-rated MOSFETs or gate drivers without excessive derating.
What is the thermal resistance of P6SMB160CAHE3_A/H, and how does it affect layout?
P6SMB160CAHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe operation under repetitive surges, PCB layout must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - as specified in the datasheet - to achieve rated power dissipation and avoid thermal runaway during sustained transient events.
Can P6SMB160CAHE3_A/H replace P6SMB160A in a design?
No - P6SMB160CAHE3_A/H is bidirectional, while P6SMB160A is unidirectional with a cathode band. Substituting them requires verifying circuit polarity: P6SMB160A blocks forward current in one direction and clamps reverse transients, whereas P6SMB160CAHE3_A/H clamps in both directions. Using P6SMB160CAHE3_A/H in place of P6SMB160A may cause unintended conduction in DC-biased lines unless the application is inherently AC or floating.
