Product details
Overview
P4SMA16A-E3/5A 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 16 V standoff voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, 22.5 V maximum clamping voltage (VC) at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the P4SMA16A-E3/5A datasheet, P4SMA16A-E3/5A pinout, P4SMA16A-E3/5A application, or P4SMA16A-E3/5A equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, clamping performance under repetitive transients, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P4SMA16A-E3/5A operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 µA at 13.6 V), while thermal resistance (RθJA = 120 °C/W) supports operation up to 150 °C junction temperature.
It delivers 400 W peak pulse power per 10/1000 µs waveform on standard 5.0 mm × 5.0 mm copper pads, with clamping response time <1.0 ns and incremental surge resistance optimized for fast transient suppression in DC power rails and low-voltage data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC bias margin. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during ESD or surge events. |
| VC (Clamping) | 22.5 V at 17.8 A - Peak voltage seen by protected circuit during 10/1000 µs transient; limits stress on downstream ICs. |
| PPPM | 400 W - Sustained transient energy absorption capability without failure; rated for 0.01% duty cycle. |
| IPPM | 17.8 A - Peak surge current handled at VC; determines minimum trace width and PCB layout robustness. |
| TJ max | 150 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with cathode band marking; compatible with automated pick-and-place. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 (260 °C reflow peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side of protected line; establishes unidirectional conduction path. |
| Cathode | Reverse voltage sensing / Clamping output | Marked with band; tied to higher-potential rail (e.g., VCC or signal line); sinks surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 Level 3 surges (1 kV/2 Ω) on 12 V systems. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage exposure to sensitive 16 V-rated components such as CAN transceivers or MCU I/O pins. |
| AEC-Q101 qualified (P4SMA16A variant) | Validated for automotive applications including body control modules and ADAS sensor interfaces. |
| MSL Level 1 moisture sensitivity | Permits standard SMT reflow without baking; reduces manufacturing overhead and handling risk. |
| Glass passivated junction | Ensures long-term parameter stability and low leakage drift across temperature and lifetime. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs and LIN bus lines in BCMs exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role: Unidirectional TVS placed between VBAT and ground to clamp transients before they reach LDOs and microcontrollers.

Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers against field-wiring induced surges. IC Role / Device Role: Mounted directly at connector entry point to shunt induced spikes before optocoupler or Schmitt trigger input stages. Use Value: Withstands 17.8 A peak current and maintains <1 µA leakage at 13.6 V, preserving input threshold accuracy. |
| Telecom Power Supply Rail Protection | Consumer Appliance Motor Driver Interface |
Use Scenario: Shielding secondary-side 12–15 V DC outputs in telecom AC/DC adapters from lightning-induced surges on connected equipment. IC Role / Device Role: Placed across output capacitor terminals to suppress differential-mode transients propagating into powered devices. Use Value: 400 W rating handles repeated 10/1000 µs surges without degradation; RoHS-compliant E3 suffix meets regulatory requirements. |
Use Scenario: Protecting gate driver signal lines in white-goods motor inverters subject to commutation noise and back-EMF spikes. IC Role / Device Role: Connected between PWM output and ground to clamp fast-rising edge transients generated by MOSFET switching. Use Value: Sub-1 ns response time prevents false triggering of level-shifters; SMA package fits tight board space near motor connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VWM (13.6 V), slightly higher VC (23.2 V), identical SMA package and 400 W rating. | Widely used in industrial power supplies; less commonly AEC-Q101 qualified in standard grade. | Select SMAJ16A if AEC-Q101 is not required and sourcing flexibility across multiple distributors is prioritized. |
| 1.5SMC16A | Higher package thermal mass (SMC/DO-214AB); same electrical specs but RθJA = 40 °C/W vs. 120 °C/W. | Better suited for high-duty-cycle or high-ambient environments where sustained power dissipation matters. | Choose 1.5SMC16A when board-level airflow is limited and junction temperature rise must be minimized during repetitive surges. |
Compared with SMAJ16A and 1.5SMC16A, the P4SMA16A-E3/5A offers tighter VBR tolerance, AEC-Q101 qualification out-of-box, and optimized cost-per-unit in high-volume 13" tape-and-reel delivery - making it preferred for automotive-tier-1 and industrial OEM designs requiring traceable compliance.

FAQ
What is the clamping voltage of the P4SMA16A-E3/5A at its rated peak pulse current?
The P4SMA16A-E3/5A has a maximum clamping voltage (VC) of 22.5 V at 17.8 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads and represents the upper voltage limit imposed on the protected circuit during worst-case surge conditions. The P4SMA16A-E3/5A maintains this clamping performance across its full operating temperature range.
Is the P4SMA16A-E3/5A AEC-Q101 qualified?
Yes, the P4SMA16A-E3/5A is AEC-Q101 qualified - confirmed by Vishay's documentation stating that the "_A" suffix variants (including P4SMA16A) are available in AEC-Q101 qualified versions with ordering codes ending in HE3 or HM3. The P4SMA16A-E3/5A uses the E3 commercial-grade RoHS-compliant suffix, and AEC-Q101 qualification applies to the base P4SMA16A device family per revision notes in the datasheet.
What does the "E3/5A" suffix mean in P4SMA16A-E3/5A?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "/5A" indicates packaging in 13-inch diameter plastic tape and reel, containing 7500 units - optimized for high-volume SMT assembly. This differs from "/61", which specifies 7-inch reels of 1800 units.
Can the P4SMA16A-E3/5A be used in bidirectional applications?
No, the P4SMA16A-E3/5A is a unidirectional TVS diode, identified by the "A" suffix (as opposed to "CA" for bidirectional). Its cathode band marks the terminal that must be connected toward the higher-potential side of the circuit. For bidirectional protection, Vishay specifies part numbers like P4SMA16CA; using P4SMA16A-E3/5A in reverse-biased AC signal paths would result in forward conduction and failure.
What is the maximum junction temperature rating for the P4SMA16A-E3/5A?
The P4SMA16A-E3/5A has a maximum junction temperature (TJ) rating of +150 °C, as specified in the Absolute Maximum Ratings table. This allows reliable operation in under-hood automotive environments and enclosed industrial enclosures. Derating curves in the datasheet show that peak pulse power must be reduced above 25 °C ambient, with 50% derating applied at 125 °C ambient per Figure 2.
