Product details
Overview
P4SMA160A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 160 V standoff voltage (VWM), 152–168 V breakdown voltage (VBR) at 1 mA, 219 V maximum clamping voltage (VC) at 1.4 A peak pulse current, and 400 W peak pulse power rating with a 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the P4SMA160A-E3/61 datasheet, P4SMA160A-E3/61 pinout, P4SMA160A-E3/61 application, or P4SMA160A-E3/61 equivalent, key selection criteria include clamping performance under 10/1000 µs transients, unidirectional polarity marking, SMA (DO-214AC) package thermal resistance (RθJA = 120 °C/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The P4SMA160A-E3/61 operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs waveform test condition, with derated peak power above 91 V (300 W) and full 400 W capability below that threshold.
Thermally, it uses an SMA (DO-214AC) package with RθJA = 120 °C/W and RθJL = 30 °C/W, mounted on 0.2" × 0.2" copper pads. It supports 40 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and operates across -65 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin in normal circuit conditions. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Voltage at which device enters controlled avalanche; tight 10.5% tolerance ensures predictable triggering. |
| VC (Clamping Voltage) | 219 V at IPPM = 1.4 A - Peak voltage seen by protected circuit during 10/1000 µs transient; critical for downstream IC survivability. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capacity under standard lightning/surge waveform; confirms suitability for IEC 61000-4-5 Level 3/4. |
| IR (Reverse Leakage) | 1.0 µA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| TJ max. | +150 °C - Enables operation in under-hood automotive or enclosed industrial environments without thermal shutdown. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with matte tin-plated leads; compatible with J-STD-002 soldering and JESD22-B102 whisker testing. |
Pinout & Package
SMA (DO-214AC) package: molded epoxy case meeting UL 94 V-0 flammability rating; cathode indicated by band on unidirectional devices; terminals are matte tin plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or low-side reference in unidirectional TVS configuration. | Enables clamping of positive transients on the cathode-connected line; must be routed to lowest-impedance ground plane. |
| Cathode | Current exit point in forward bias; connected to protected line (e.g., CAN_H, RS-485 A, 12 V rail). | Defines polarity-sensitive placement; band marking ensures correct orientation during automated placement and visual inspection. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Validated surge handling for IEC 61000-4-5 combination wave (2 Ω source impedance) up to ±1 kV on 12 V systems. |
| AEC-Q101 qualified (P4SMA160A-E3/61 variant) | Qualified for automotive applications including engine control units, body electronics, and ADAS sensor interfaces per stress test requirements. |
| Glass passivated chip junction | Ensures stable VBR over lifetime and improved humidity resistance vs. epoxy-passivated alternatives; reduces parameter drift in humid environments. |
| MSL Level 1 (JEDEC J-STD-020) | Zero floor life limitation - can be stored indefinitely at ambient conditions and placed directly into reflow without baking. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD > 15 kV contact), improving protection margin for sensitive 3.3 V or 5 V logic. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VWM (136 V), higher VC (230 V), larger SMB (DO-214AA) package (RθJA = 85 °C/W). | Better thermal performance but requires 30% more PCB area; less suitable for ultra-dense layouts. | Select when board space permits and higher thermal margin is needed for sustained surge duty cycles. |
| 1.5KE160A | Through-hole TO-204AE (DO-201AE); same electrical specs but 1.5 kW peak power rating (10/1000 µs) and higher IFSM (100 A). | Designed for legacy through-hole assembly or high-energy industrial surge protection where manual repair is acceptable. | Choose only for prototyping, repair, or applications requiring >400 W single-event handling with mechanical robustness. |
Compared with SMBJ160A and 1.5KE160A, the P4SMA160A-E3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and verified 400 W surge capability - making it preferred for new automotive and space-constrained industrial designs requiring surface-mount scalability and automotive-grade reliability.

FAQ
What is the clamping voltage of the P4SMA160A-E3/61 under a 10/1000 µs surge?
The P4SMA160A-E3/61 has a maximum clamping voltage (VC) of 219 V at 1.4 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and reflects worst-case voltage seen by protected circuitry during surge events - critical for ensuring downstream components remain within absolute maximum ratings.
Is the P4SMA160A-E3/61 AEC-Q101 qualified?
Yes, the P4SMA160A-E3/61 is AEC-Q101 qualified. Per Vishay's ordering information and revision notes, the "_A" suffix (as in P4SMA160A) indicates AEC-Q101 qualification for devices in the 6.8 V to 220 V range, and the E3/61 packaging denotes RoHS-compliant commercial grade with automotive-grade reliability validation.
What does the "E3/61" suffix mean in P4SMA160A-E3/61?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/61" specifies packaging in 7-inch plastic tape and reel, with 1800 units per reel. This format meets J-STD-002 solderability and JESD22-B102 whisker resistance Class 2 requirements - essential for high-yield SMT assembly.
Can the P4SMA160A-E3/61 be used in bidirectional applications?
No, the P4SMA160A-E3/61 is unidirectional only. Bidirectional variants use the "CA" suffix (e.g., P4SMA160CA). The "A" in P4SMA160A-E3/61 explicitly designates unidirectional polarity, with cathode marked by a band - using it in bidirectional configurations would result in forward conduction during negative transients and potential failure.
What is the thermal resistance of the P4SMA160A-E3/61?
The P4SMA160A-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" copper pads per Vishay document 88367. Its junction-to-lead resistance (RθJL) is 30 °C/W, supporting reliable power dissipation in thermally constrained layouts without additional heatsinking.
