Product details
Overview
P4SMA16A-E3/61 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 16 V standoff voltage (VWM), 17.8 V maximum clamping voltage at 1 A peak pulse current, 400 W peak pulse power rating (10/1000 μs), and operates across -65 °C to +150 °C junction temperature range - used in automotive sensor protection, industrial I/O interfaces, and consumer power rail surge suppression.
For engineers reviewing the P4SMA16A-E3/61 datasheet, P4SMA16A-E3/61 pinout, P4SMA16A-E3/61 application, or P4SMA16A-E3/61 equivalent, this device delivers verified transient suppression performance with AEC-Q101 qualification, SMA (DO-214AC) package compatibility, low incremental surge resistance, and precise 15.2–16.8 V breakdown voltage at 1 mA test current - critical for ESD and inductive switching protection in space-constrained designs.
Technical Context
The P4SMA16A-E3/61 employs a glass-passivated silicon junction optimized for fast response (<1 ns) to transient overvoltages and low clamping ratio (VC/VBR ≈ 1.33). Its unidirectional polarity uses cathode-band marking and supports only reverse-biased transient suppression - not bidirectional operation.
Thermal design relies on RθJA = 120 °C/W and RθJL = 30 °C/W, requiring minimum 0.2" × 0.2" copper pads per terminal for rated 400 W pulse handling. Derating applies above TA = 25 °C per Fig. 2, and it meets J-STD-020 MSL Level 1 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13.6 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 15.2–16.8 V at IT = 1 mA - Confirmed reverse breakdown threshold; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 22.5 V at IPPM = 1 A (10/1000 μs) - Peak voltage seen by protected circuit; enables robust IC-level protection. |
| PPPM (Peak Pulse Power) | 400 W - Sustains single 10/1000 μs surges without failure; derates to 300 W above 91 V. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Negligible standby current; preserves low-power system integrity. |
| TJ max. | +150 °C - Enables under-hood automotive and high-temperature industrial deployment. |
| Package | SMA (DO-214AC) - Standardized surface-mount footprint; compatible with automated placement and IPC-7351B land patterns. |

| MSL Level 1, 260 °C peak reflow | Supports lead-free assembly without preconditioning; eliminates moisture-related popcorning risk. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach sensitive input stages. Use Value: Maintains 13.6 V standoff while limiting clamped voltage to 22.5 V, preserving signal integrity and preventing latch-up in 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers against field-wiring induced surges and relay contact bounce. IC Role / Device Role / Timing Role: Reverse-biased TVS on 24 V DC input lines to absorb repetitive 400 W transients without thermal runaway. Use Value: Withstands 1000+ surge events at rated power due to low thermal resistance (RθJL = 30 °C/W) and stable VBR drift <0.086 %/°C. |
| Consumer Power Adapter Protection | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters and USB PD chargers exposed to lightning-induced surges on DC output rails. IC Role / Device Role / Timing Role: Standoff-rated TVS across 12 V or 19 V output to prevent damage to downstream DC-DC converters and load switches. Use Value: 22.5 V clamping voltage ensures protected circuits remain within absolute maximum ratings even during worst-case 10/1000 μs transients. |
Use Scenario: Front-end protection of Ethernet PHYs and RS-485 transceivers in network equipment subjected to induced surges from nearby AC mains or antenna coupling. IC Role / Device Role / Timing Role: Unidirectional TVS on VDD supply pins and data lines to suppress common-mode transients up to 400 W. Use Value: Low leakage (1.0 μA) avoids loading high-impedance bias networks; fast response (<1 ns) prevents data corruption during sub-microsecond spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same VWM (13.6 V), higher PPPM (600 W), larger SMB (DO-214AA) package (4.58 mm × 3.94 mm vs. SMA's 4.50 mm × 2.79 mm). | Preferred where higher surge margin is required and board space allows larger footprint. | Select SMBJ16A when 600 W pulse rating is mandatory and layout accommodates 30 % larger body size. |
| 1.5SMC16A | Same VWM and VC, but higher PPPM (1500 W), DO-214AB (SMC) package (7.11 mm × 6.22 mm), higher RθJA (60 °C/W). | Suitable for high-reliability industrial power supplies needing multi-kW surge capability. | Choose 1.5SMC16A only if PCB area permits SMC footprint and thermal management supports higher junction rise. |
Compared with SMBJ16A and 1.5SMC16A, the P4SMA16A-E3/61 offers optimal balance of compact SMA packaging, AEC-Q101 qualification, and 400 W surge handling - making it the preferred choice for space-constrained automotive and consumer electronics where standardized reflow compatibility and proven field reliability are prioritized over extreme power rating.

FAQ
What is the breakdown voltage range for P4SMA16A-E3/61?
The P4SMA16A-E3/61 has a specified breakdown voltage (VBR) range of 15.2 V to 16.8 V at a test current (IT) of 1 mA. This range is confirmed in the Vishay datasheet (Document Number: 88367, Revision: 09-Jan-2024) and reflects manufacturing tolerance under standardized test conditions. The P4SMA16A-E3/61 maintains this tight VBR window across its qualified temperature range, supporting reliable transient turn-on behavior in automotive and industrial systems.
Is P4SMA16A-E3/61 suitable for automotive applications?
Yes, the P4SMA16A-E3/61 is AEC-Q101 qualified for automotive use, as explicitly stated in the Vishay datasheet. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per AEC standards. The P4SMA16A-E3/61 is commonly deployed in engine control units, body electronics, and ADAS sensor interfaces where sustained operation from -65 °C to +150 °C and immunity to load-dump transients are required.
What does the "E3/61" suffix indicate in P4SMA16A-E3/61?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads, while "/61" specifies packaging in 7-inch diameter plastic tape and reel containing 1800 units. This ordering code aligns with Vishay's standard delivery format for automated SMT assembly. The P4SMA16A-E3/61 is not halogen-free (that requires "M3") nor AEC-Q101 automotive grade (which would use "HE3" or "HM3"), confirming its commercial-grade qualification status.
How does P4SMA16A-E3/61 compare to bidirectional TVS diodes like P4SMA16CA?
The P4SMA16A-E3/61 is unidirectional and intended for DC line protection with defined polarity, whereas P4SMA16CA is bidirectional and suited for AC or floating-signal applications. The P4SMA16A-E3/61 exhibits forward conduction (VF ≈ 3.5 V at 25 A) and reverse clamping only; P4SMA16CA clamps symmetrically in both directions. Their VWM, VBR, and VC values differ accordingly - using P4SMA16A-E3/61 in place of P4SMA16CA without circuit redesign risks improper protection.
What is the maximum clamping voltage of P4SMA16A-E3/61 under surge conditions?
The P4SMA16A-E3/61 has a maximum clamping voltage (VC) of 22.5 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 1 A. This value is measured per Figure 1 and Table on page 2 of the Vishay datasheet and represents the upper limit of voltage imposed on the protected circuit during transient events. The P4SMA16A-E3/61 achieves this clamping performance while maintaining low incremental surge resistance and fast response time.
