Product details
Overview
P4SMA160CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on signal and power lines. It features a 160 V standoff voltage (VWM), 179 V breakdown voltage (VBR min), 219 V maximum clamping voltage at 1.4 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive applications.
For engineers reviewing the P4SMA160CAHE3/61 datasheet, P4SMA160CAHE3/61 pinout, P4SMA160CAHE3/61 application, or P4SMA160CAHE3/61 equivalent, key selection criteria include bidirectional transient suppression capability, SMA (DO-214AC) package compatibility with automated SMT assembly, thermal derating above 25 °C, and compliance with automotive reliability standards.
Technical Context
The P4SMA160CAHE3/61 operates as a bidirectional avalanche diode, symmetrically clamping positive and negative transients across its terminals without polarity marking. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for protecting sensitive inputs against ESD and inductive switching spikes.
Rated for 400 W peak pulse power (10/1000 µs waveform) and 3.3 W steady-state power dissipation, it is thermally characterized with RθJA = 120 °C/W and RθJL = 30 °C/W, requiring minimum 0.2" × 0.2" copper pads per terminal for full power rating. It meets MSL Level 1 and JESD201 Class 2 whisker resistance.

Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive kickback in 12 V/24 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector or IC input pins to limit transient voltage before reaching sensitive front-end circuitry. Use Value: Maintains signal integrity below 219 V clamping threshold during 10/1000 µs surges up to 1.4 A, preventing latch-up or damage to 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding 4–20 mA current loop and 0–10 V analog inputs in programmable logic controllers exposed to field wiring transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminals, coordinated with series current-limiting resistors and filtering capacitors. Use Value: Withstands repetitive 400 W pulses without degradation, enabling long-term reliability in factory automation environments with frequent motor switching noise. |
| Telecom Line Card Surge Protection | Consumer Power Adapter Output Clamping |
Use Scenario: Secondary-level surge suppression on Ethernet PHY interfaces, DSL line drivers, and PoE-powered ports subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Fast-response shunt device placed after primary GDT or MOV, providing precise clamping where low let-through voltage is required. Use Value: 219 V clamping ensures downstream PHY ICs (e.g., IEEE 802.3af compliant) remain within absolute maximum ratings during combined-mode surges. |
Use Scenario: Output-side transient suppression on AC/DC adapters for smart home devices, preventing voltage spikes from damaging USB-C PD controllers or microcontrollers. IC Role / Device Role / Timing Role: Final-stage TVS on regulated DC output rail (e.g., 5 V, 12 V), absorbing coupling noise from internal switching or external cable discharge events. Use Value: AEC-Q101 qualification and 150 °C max junction temperature support extended operation in enclosed, thermally constrained enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Same VWM/VBR/VC specs but in larger SMB (DO-214AA) package; 600 W PPPM rating | Higher power handling supports heavier industrial surges; requires larger PCB footprint | Select when higher pulse energy margin is needed and board space allows SMB footprint |
| 1.5KE160CA | Through-hole DO-15 package; same 160 V VWM but 1.5 kW PPPM; higher junction capacitance (~100 pF) | Not suitable for high-speed data lines due to higher capacitance; limited to power rail or low-frequency signal protection | Choose only for legacy through-hole designs or where extreme surge energy (>1.5 kW) must be absorbed |
Compared with SMBJ160CA and 1.5KE160CA, the P4SMA160CAHE3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and 400 W surge capability-making it preferred for space-constrained automotive and industrial SMT designs where reliability and manufacturability are prioritized over maximum pulse power.

FAQ
What is the clamping voltage of P4SMA160CAHE3/61 at its rated peak pulse current?
The P4SMA160CAHE3/61 has a maximum clamping voltage (VC) of 219 V at 1.4 A peak pulse current (IPPM), measured using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during transient events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2, electrical characteristics table.
Is P4SMA160CAHE3/61 suitable for automotive applications?
Yes, P4SMA160CAHE3/61 is AEC-Q101 qualified (indicated by the HE3 suffix), meaning it has undergone rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-for use in automotive electronics. It is specified for junction temperatures up to +150 °C and meets MSL Level 1 for lead-free reflow, making it appropriate for engine control units, ADAS sensors, and body electronics.
Does P4SMA160CAHE3/61 have polarity markings?
No, P4SMA160CAHE3/61 is a bidirectional TVS diode and carries no polarity marking such as a cathode band. Its symmetrical construction allows identical clamping behavior for both positive and negative transients, and either terminal may be connected to line or ground without functional impact-consistent with all CA-suffix devices in the P4SMA series.
What is the thermal resistance of P4SMA160CAHE3/61?
The P4SMA160CAHE3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, and a junction-to-lead resistance (RθJL) of 30 °C/W. These values are critical for calculating safe operating area under sustained power dissipation or repetitive surge conditions.
How does the HE3 suffix affect P4SMA160CAHE3/61's compliance status?
The HE3 suffix on P4SMA160CAHE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification. It confirms compliance with automotive reliability standards, halogen-free material content, and adherence to JESD201 Class 2 whisker resistance-distinguishing it from commercial-grade E3 or M3 variants and enabling use in safety-critical vehicle subsystems.
