Product details
Overview
P4SMA160A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 219 V maximum clamping voltage (VC) at 1.4 A peak pulse current (IPPM). It delivers 400 W peak pulse power (10/1000 µs waveform) and is AEC-Q101 qualified for automotive-grade reliability in power rail and signal line protection.
For engineers reviewing the P4SMA160A-E3/5A datasheet, P4SMA160A-E3/5A pinout, P4SMA160A-E3/5A application, or P4SMA160A-E3/5A equivalent, key selection factors include its 136 V reverse leakage limit at VWM, -65 °C to +150 °C operating junction temperature range, RoHS-compliant matte tin-plated leads, and suitability for automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal.
Technical Context
The P4SMA160A-E3/5A uses a glass passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes. Its unidirectional polarity features a cathode band marking and supports only forward-biased conduction during clamping.
Thermal performance is defined by RθJA = 120 °C/W (junction-to-ambient, typical) and RθJL = 30 °C/W (junction-to-lead), requiring thermal pad layout per DO-214AC standard for sustained 3.3 W power dissipation. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VWM/VBR/VC specs but SMB (DO-214AA) package; 10 % larger footprint and 10 % higher RθJA (130 °C/W). | Preferred where existing layout accommodates larger pad area and higher thermal mass is acceptable for lower-cost assembly. | Select SMBJ160A if board space permits and legacy SMB tooling is in place; verify thermal relief design for 3.3 W dissipation. |
| 1.5SMC160A | Higher PPPM (1500 W) and larger SMC (DO-214AB) package; VC = 259 V at 6.1 A - 18 % higher clamping than P4SMA160A-E3/5A. | Suited for high-energy surge zones (e.g., AC mains inputs) where lower clamping precision is traded for greater energy absorption. | Choose 1.5SMC160A only when system-level testing confirms 259 V clamping is acceptable for downstream components. |
Compared with SMBJ160A and 1.5SMC160A, P4SMA160A-E3/5A offers optimal balance of compact SMA footprint, industry-standard 400 W surge rating, and tight 219 V clamping-making it ideal for space-constrained automotive and industrial PCBs where thermal management and layout density are critical.

FAQ
What is the maximum clamping voltage of the P4SMA160A-E3/5A under specified test conditions?
The P4SMA160A-E3/5A has a maximum clamping voltage (VC) of 219 V when subjected to a 10/1000 µs waveform at 1.4 A peak pulse current (IPPM). This value is measured per Figure 1 in the Vishay datasheet 88367 and reflects the worst-case voltage imposed on protected circuitry during standardized surge events. The P4SMA160A-E3/5A maintains this clamping performance across its full operating temperature range.
Is the P4SMA160A-E3/5A suitable for automotive applications?
Yes, the P4SMA160A-E3/5A is AEC-Q101 qualified and explicitly listed in Vishay's documentation as available in automotive-grade ordering codes (e.g., P/NHE3). It operates from -65 °C to +150 °C, meets MSL Level 1, and is validated for use in engine control units, body electronics, and ADAS power supplies where transient immunity and long-term reliability are mandatory. The P4SMA160A-E3/5A carries full automotive traceability and process controls.
What does the "-E3/5A" suffix indicate in P4SMA160A-E3/5A?
The "-E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/5A" specifies packaging in 13-inch diameter plastic tape and reel containing 7500 units. This format aligns with IPC-7351 standards for automated pick-and-place equipment and supports high-throughput SMT lines. The P4SMA160A-E3/5A is not halogen-free (that requires "-M3") nor AEC-Q101 qualified (that requires "-HE3" or "-HM3").
How does the thermal performance of P4SMA160A-E3/5A compare to larger package alternatives?
The P4SMA160A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads-higher than SMBJ160A (130 °C/W) but lower than 1.5SMC160A (100 °C/W). Its RθJL of 30 °C/W enables efficient heat transfer to PCB traces. For continuous 3.3 W dissipation, the P4SMA160A-E3/5A requires careful thermal pad design; the P4SMA160A-E3/5A outperforms SMBJ160A in footprint efficiency without sacrificing thermal safety margins.
Can P4SMA160A-E3/5A be used in bidirectional configurations?
No, the P4SMA160A-E3/5A is strictly unidirectional, as confirmed by its part number suffix "A" (not "CA") and cathode band marking. Bidirectional operation requires the CA variant (e.g., P4SMA160CA), which lacks polarity marking and exhibits symmetrical VBR in both directions. Using P4SMA160A-E3/5A in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles. Always verify polarity alignment before integrating the P4SMA160A-E3/5A.
