Product details
Overview
P4SMA16CA-E3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on signal and power lines. It features a 16 V standoff voltage (VWM), 17.8 A peak pulse current (IPPM) at 10/1000 µs, 22.5 V maximum clamping voltage (VC), and 400 W peak pulse power rating. It is used to protect sensitive ICs and MOSFETs in industrial sensor interfaces and telecom line circuits.
For engineers reviewing the P4SMA16CA-E3/61 datasheet, P4SMA16CA-E3/61 pinout, P4SMA16CA-E3/61 application, or P4SMA16CA-E3/61 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal derating curves, and direct alternatives with documented differences in breakdown voltage tolerance and polarity configuration.
Technical Context
The P4SMA16CA-E3/61 operates as a bidirectional avalanche diode, symmetrically clamping transient voltages above ±22.5 V while maintaining ≤1.0 µA reverse leakage at 13.6 V. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting high-speed data lines against ESD and inductive switching spikes.
Rated for 400 W peak pulse power (10/1000 µs waveform) and 3.3 W steady-state power dissipation, it is mounted on 5.0 mm × 5.0 mm copper pads per terminal and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is RoHS-compliant (E3 suffix) and qualified to AEC-Q101 when ordered with HE3/HM3 suffixes.
Key Specifications

IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed across differential bus lines (A/B) and power rails to limit transient overvoltage. Use Value: Limits clamped voltage to 22.5 V, preventing damage to 3.3 V or 5 V transceivers while supporting >100 kbps data rates without signal distortion. |
Use Scenario: Safeguarding Ethernet PHY ports and DSL line drivers against ESD events and induced surges in residential gateways and base stations. IC Role / Device Role / Timing Role: Primary front-end transient suppressor on twisted-pair input lines, coordinated with secondary GDT or MOV stages. Use Value: Fast <1 ns response captures initial ESD edge; low 1.0 µA leakage avoids DC bias shift on high-impedance receive paths. |
| Consumer Power Adapter Input | Automotive Body Control Module |
|
Use Scenario: Suppressing line-to-line and line-to-ground surges on AC/DC adapter primary-side rectifier outputs and secondary-side 12 V rails. IC Role / Device Role / Timing Role: Secondary-level TVS after bulk filtering, absorbing residual transients that bypass upstream MOVs. Use Value: 400 W rating handles repetitive 10/1000 µs surges up to 0.01% duty cycle; 150 °C TJ max supports enclosed, thermally constrained enclosures. |
Use Scenario: Protecting LIN bus transceivers and door module microcontrollers from load dump and alternator ripple in 12 V vehicle networks. IC Role / Device Role / Timing Role: Bidirectional clamp on LIN data line and VBAT-supplied logic rails, qualified per AEC-Q101 when specified as HE3 variant. Use Value: Symmetric clamping prevents false triggering on bidirectional LIN signaling; 13.6 V VWM aligns with 12 V system nominal voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Same VWM (13.6 V) and VC (22.5 V), but 600 W PPPM rating in larger SMB (DO-214AA) package; higher thermal mass. | Preferred where board space allows larger footprint and higher surge margin is required (e.g., outdoor telecom cabinets). | Select SMBJ16CA if 600 W surge handling is mandatory and PCB layout accommodates 5.3 mm × 4.6 mm footprint. |
| 1.5KE16CA | Through-hole TO-204AE (DO-201AE) package; same VWM/VC specs but 1500 W PPPM; requires wave solder or hand-soldering. | Used in legacy industrial power supplies and high-reliability military designs where through-hole mounting is mandated. | Choose 1.5KE16CA only when through-hole assembly is required and 1500 W surge capacity justifies larger mechanical footprint and assembly cost. |
Compared with P4SMA16CA-E3/61, SMBJ16CA offers higher surge margin in a slightly larger SMT package, while 1.5KE16CA provides maximum ruggedness via through-hole construction-neither is pin-compatible, but both serve overlapping protection roles with trade-offs in size, mounting method, and power rating.

FAQ
What is the clamping voltage of the P4SMA16CA-E3/61 under a 10/1000 µs surge?
The P4SMA16CA-E3/61 clamps to a maximum of 22.5 V when subjected to its rated peak pulse current of 17.8 A under the standardized 10/1000 µs waveform. This value is measured at the device terminals with specified PCB pad layout (0.2" × 0.2" copper per terminal) and represents the upper bound of voltage imposed on protected circuitry during surge events.
Is the P4SMA16CA-E3/61 suitable for automotive applications?
The P4SMA16CA-E3/61 itself is RoHS-compliant and commercial-grade; however, Vishay offers AEC-Q101-qualified variants under ordering codes such as P4SMA16CAHE3_A. For automotive use, specify the HE3 or HM3 suffix to ensure qualification-P4SMA16CA-E3/61 alone does not carry AEC-Q101 certification.
How does the bidirectional design of the P4SMA16CA-E3/61 affect its placement on a PCB?
The P4SMA16CA-E3/61 has no polarity marking and functions identically in either orientation, simplifying layout and eliminating orientation errors during automated placement. This symmetry allows direct placement across differential pairs (e.g., RS-485 A/B) or AC-coupled signal lines without regard to anode/cathode alignment.
What is the maximum steady-state power dissipation for the P4SMA16CA-E3/61?
The P4SMA16CA-E3/61 has a maximum steady-state power dissipation (PD) of 3.3 W at TA = 50 °C on an infinite heatsink. In typical surface-mount applications with standard PCB copper, derating applies per Figure 2 in the datasheet-actual usable power depends on ambient temperature and thermal pad design.
Does the P4SMA16CA-E3/61 meet any industry surge immunity standards?
Yes-the 400 W peak pulse power rating of the P4SMA16CA-E3/61 under the 10/1000 µs waveform aligns with the test conditions of IEC 61000-4-5 for Level 4 surge immunity (4 kV line-to-line, 2 kV line-to-ground). System-level compliance requires proper PCB layout and coordination with upstream protection devices.
