Product details
Overview
P4SMA110CA-E3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 94.0 V standoff voltage (VWM), 105–116 V breakdown voltage (VBR) at 1 mA, 152 V maximum clamping voltage (VC) at 2.0 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform) - suitable for protecting automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the P4SMA110CA-E3/5A datasheet, P4SMA110CA-E3/5A pinout, P4SMA110CA-E3/5A application, or P4SMA110CA-E3/5A equivalent, key selection considerations include bidirectional clamping capability, 150 °C max junction temperature, RoHS-compliant matte tin plating, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
The P4SMA110CA-E3/5A operates as a bidirectional avalanche diode, delivering symmetrical clamping in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while its low incremental surge resistance enables rapid response to ESD and lightning-induced transients.
Thermally, it exhibits RθJA = 120 °C/W and RθJL = 30 °C/W, requiring minimal copper pad area (0.2" × 0.2") for rated 400 W pulse handling. Derating applies above TA = 25 °C per Figure 2, and repetitive operation is limited to 0.01% duty cycle - consistent with IEC 61000-4-5 surge immunity testing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 94.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 105–116 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 152 V at IPPM = 2.0 A - Peak voltage seen by protected circuit under 10/1000 µs surge; determines downstream component stress. |
| PPPM | 400 W (≤91 V); 300 W (>91 V) - Surge energy absorption capacity per single 10/1000 µs pulse; validates compliance with IEC 61000-4-5 Level 4. |
| ID (Leakage) | <1.0 µA at VWM - Minimal standby current draw; preserves signal integrity and battery life in always-on systems. |
| TJ max | +150 °C - Enables use in under-hood automotive and high-ambient industrial environments without thermal derating penalties. |
| Package | SMA (DO-214AC) - Standardized SMT footprint compatible with JEDEC MS-013; supports automated pick-and-place and reflow. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional device with no polarity marking. Cathode/anode terminals are functionally symmetric; terminals are matte tin-plated for J-STD-002 solderability and JESD22-B102 whisker resistance (Class 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Provides symmetrical conduction path during positive or negative surges; connects to protected line or ground reference. |

IC Role / Device Role / Timing Role: Standoff-rated TVS shunting surge current away from optocoupler input stages and upstream protection ICs. Use Value: Withstands 400 W pulses without degradation, maintaining <1 µA leakage at 94 V to avoid false triggering of 24 V logic thresholds. |
| Telecom Line Interface | Consumer USB Port ESD Protection |
|
Use Scenario: Shielding RS-485 transceivers in building automation gateways from induced lightning surges on long-distance twisted-pair cabling. IC Role / Device Role / Timing Role: Primary clamping device on differential pair, operating symmetrically to preserve common-mode rejection during fast transients. Use Value: Clamps both polarities identically to ≤152 V, ensuring transceiver survival under 10/1000 µs 4 kV surges per IEC 61000-4-5 Ed. 3. |
Use Scenario: Secondary-level ESD protection on USB 2.0 data lines (D+, D−) in smart home hubs, supplementing internal IC-level protection. IC Role / Device Role / Timing Role: Fast-response external TVS absorbing >8 kV contact discharge (IEC 61000-4-2) before energy reaches PHY layer. Use Value: Sub-1 ns response time and 152 V clamping prevent latch-up in USB transceivers while adding only 15 pF capacitance (typical at VWM). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VWM (94 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 needed and board space allows larger footprint; not drop-in due to different pad layout. | Select SMBJ110CA when 600 W pulse rating is required and PCB real estate permits larger package. |
| 1.5KE110CA | Same VWM/VBR/VC specs, through-hole DO-201AD package, 1500 W PPPM rating, higher thermal mass but incompatible with SMT assembly. | Used in legacy or high-reliability through-hole designs; unsuitable for automated SMT lines or space-constrained layouts. | Choose 1.5KE110CA only for prototyping, repair, or non-SMT applications where manual assembly is acceptable. |
Compared with SMBJ110CA and 1.5KE110CA, the P4SMA110CA-E3/5A delivers optimal balance of compact SMT form factor, 400 W surge capability, and commercial-grade cost - making it ideal for volume production of automotive and industrial electronics where board space and assembly efficiency are critical.

FAQ
What is the maximum clamping voltage of the P4SMA110CA-E3/5A under a 10/1000 µs surge?
The P4SMA110CA-E3/5A has a maximum clamping voltage (VC) of 152 V at 2.0 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet (Document Number: 88367, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the P4SMA110CA-E3/5A suitable for automotive applications?
The P4SMA110CA-E3/5A is RoHS-compliant and manufactured to Vishay's commercial-grade specifications. While it shares identical electrical characteristics with AEC-Q101-qualified variants (e.g., P4SMA110CAHE3_A), the P4SMA110CA-E3/5A itself is not AEC-Q101 certified. For automotive production, specify the HE3 or HM3 suffix variants instead.
What does the "CA" suffix indicate in P4SMA110CA-E3/5A?
The "CA" suffix in P4SMA110CA-E3/5A denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional "A" variants, CA devices have no cathode band marking and are used where polarity of transient events is undefined or alternating.
What is the standoff voltage (VWM) rating of the P4SMA110CA-E3/5A?
The P4SMA110CA-E3/5A has a standoff voltage (VWM) of 94.0 V, representing the maximum continuous DC or RMS voltage that can be applied without initiating significant conduction. This value ensures reliable operation in 72–96 V nominal systems such as 24 V automotive subsystems with load-dump margins.
Does the P4SMA110CA-E3/5A require special PCB layout considerations?
Yes - the P4SMA110CA-E3/5A should be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve its rated 400 W peak pulse power. Short, low-inductance traces to ground or protected nodes are essential; longer traces increase clamping voltage and reduce effective surge handling capability.
