Product details
Overview
P4SMA160AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on power and signal lines. It features a 160 V standoff voltage (VWM), 171 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 1.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4SMA160AHE3/61 datasheet, P4SMA160AHE3/61 pinout, P4SMA160AHE3/61 application, or P4SMA160AHE3/61 equivalent, key selection considerations include its AEC-Q101 qualification, SMA (DO-214AC) package compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 120 °C/W) for board-level thermal design.
Technical Context
This TVS diode operates as a clamping device that conducts above its breakdown voltage to divert transient energy away from sensitive downstream circuitry. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the low incremental surge resistance enables effective voltage limiting during ESD and lightning-induced surges.
The device is rated for repetitive 10/1000 µs pulses at 0.01% duty cycle (400 W up to 91 V; 300 W above 91 V), with derating above 25 °C per Fig. 2. It meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101 for automotive under-hood and chassis applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 219 V at IPPM = 1.4 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Energy-handling capability for standardized 10/1000 µs waveform; supports IEC 61000-4-5 Level 3/4 surge immunity. |
| ID (Reverse Leakage) | 1.0 µA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient; informs PCB copper pad sizing (0.2" × 0.2") for reliable power dissipation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads. Cathode indicated by a band on the body; anode is unmarked end. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current toward ground when voltage exceeds VBR. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness - suitable for engine control, ADAS sensors, and infotainment power rails. |
| Glass passivated junction | Stable electrical characteristics over lifetime and environmental stress; eliminates risk of junction corrosion in humid or chemically aggressive environments. |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 260 °C peak; no pre-baking required prior to assembly. |
| 400 W peak pulse power | Handles IEC 61000-4-5 combination wave surges (e.g., 2 Ω/12 Ω source impedance) without degradation across ≥1000 cycles. |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes overvoltage overshoot during fast transients; critical for protecting 150 V-rated MOSFETs and gate drivers. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional clamping element placed between signal line and chassis ground; responds within <1 ns to suppress transients exceeding 136 V.

IC Role / Device Role / Timing Role: Clamping diode placed between +48 V output and ground; limits transient excursions during hot-swap or cable fault conditions. Use Value: Maintains safe operating area for 60 V-rated DC-DC controllers and prevents catastrophic failure during 1 kV/0.5 J surge events. |
Use Scenario: Output-stage transient suppression in USB-C PD adapters and multi-USB wall chargers handling variable 5–20 V outputs. IC Role / Device Role / Timing Role: Unidirectional TVS on regulated output rail; activated only during abnormal open-load or short-circuit recovery spikes. Use Value: Eliminates need for secondary overvoltage crowbar circuits while meeting UL 62368-1 transient immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A | Same VWM (136 V), slightly higher VC (224 V), identical SMA package and 400 W rating; no AEC-Q101 qualification. | Commercial/industrial use only; not approved for automotive production programs requiring PPAP documentation. | Select SMAJ160A for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
| 1.5SMC160A | Higher package thermal mass (DO-214AB), 1500 W PPPM rating, same VWM/VC specs; larger footprint (7.11 mm × 6.22 mm vs. 4.5 mm × 3.99 mm). | Preferred for high-energy surge environments (e.g., outdoor telecom cabinets); requires PCB layout revision due to size difference. | Choose 1.5SMC160A when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger package. |
Compared with SMAJ160A and 1.5SMC160A, P4SMA160AHE3/61 uniquely combines AEC-Q101 qualification, compact SMA footprint, and verified 400 W surge capability - making it the optimal choice for space-constrained automotive electronics where qualification traceability and thermal performance are jointly critical.

FAQ
What is the meaning of the "HE3" suffix in P4SMA160AHE3/61?
The "HE3" suffix in P4SMA160AHE3/61 indicates RoHS-compliant construction with AEC-Q101 qualification. The "H" denotes automotive-grade packaging and test screening, "E3" confirms lead-free matte tin plating and compliance with JEDEC JESD201 Class 2 whisker resistance, and "/61" specifies 1800-unit 7-inch tape-and-reel packaging.
Does P4SMA160AHE3/61 support bidirectional transient suppression?
No, P4SMA160AHE3/61 is a unidirectional TVS diode. Its cathode band marks the terminal that must be connected to the protected line, with the anode grounded. For bidirectional protection, Vishay offers the P4SMA160CA variant - which has symmetric clamping in both polarities and no polarity marking.
What is the maximum allowable PCB pad size for P4SMA160AHE3/61 to achieve its rated 400 W peak pulse power?
To achieve the full 400 W peak pulse power rating, P4SMA160AHE3/61 must be mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Smaller pads reduce thermal dissipation and derate the PPPM capability - e.g., 0.1" × 0.1" pads limit power to ~250 W.
How does the temperature coefficient of VBR affect P4SMA160AHE3/61 performance in automotive under-hood applications?
P4SMA160AHE3/61 has a VBR temperature coefficient of 0.108 %/°C. Over a -40 °C to +150 °C junction range, this results in ±16.8 V drift in breakdown voltage - meaning VBR shifts from ~135 V at -40 °C to ~185 V at +150 °C. System designers must ensure downstream ICs tolerate this full range during cold-crank and hot-soak conditions.
Is P4SMA160AHE3/61 compatible with lead-free reflow soldering processes?
Yes, P4SMA160AHE3/61 is fully compatible with lead-free reflow soldering. It meets J-STD-020 MSL Level 1 with a maximum peak temperature of 260 °C, and its matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards - enabling direct integration into standard Pb-free SMT lines without pre-baking.
