Product details
Overview
P4SMA110CA-M3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 110 V standoff voltage (VWM), 152 V maximum clamping voltage (VC) at 2.0 A peak pulse current (IPPM), and 400 W peak pulse power capability with a 10/1000 µs waveform. It is used in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P4SMA110CA-M3/5A datasheet, P4SMA110CA-M3/5A pinout, P4SMA110CA-M3/5A application, or P4SMA110CA-M3/5A equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under transient stress, thermal derating curves, and direct alternatives qualified for bidirectional surge protection in commercial and AEC-Q101-compliant designs.
Technical Context
The P4SMA110CA-M3/5A operates as a bidirectional avalanche diode, symmetrically clamping positive and negative transients above its breakdown voltage range of 105–116 V (VBR at 1 mA). Its low incremental surge resistance ensures stable clamping performance across repetitive 10/1000 µs pulses up to 400 W (derated to 300 W above 91 V).
Designed for surface-mount assembly on standard SMA (DO-214AC) footprints, it meets J-STD-020 MSL Level 1 with 260 °C reflow peak, has a junction-to-ambient thermal resistance of 120 °C/W, and supports operating temperatures from –65 °C to +150 °C. The halogen-free, RoHS-compliant M3 suffix confirms compliance with JEDEC JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 105–116 V at 1 mA - Verified avalanche onset range; ensures predictable turn-on during fast transients. |
| VC (Clamping Voltage) | 152 V at IPPM = 2.0 A (10/1000 µs) - Peak voltage seen by protected circuit during rated surge; critical for downstream IC survivability. |
| PPPM (Peak Pulse Power) | 400 W - Sustained transient energy absorption capacity; derates to 300 W above 91 V per Vishay spec. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Minimal standby current leakage; preserves signal integrity and low-power operation. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments. |
| Package | SMA (DO-214AC) - Standardized 2-pin surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement for thermal management. |
Pinout & Package

IC Role / Device Role / Timing Role: Primary front-end clamping element on differential pairs, coordinated with common-mode chokes. Use Value: Limits differential-mode overvoltage to ≤152 V while maintaining <1 pF junction capacitance-preserving signal integrity up to 100 Mbps. |
Use Scenario: Secondary-level surge suppression on USB 2.0 D+/D− or DisplayPort AUX channels where primary ESD diodes lack sufficient energy handling. IC Role / Device Role / Timing Role: High-energy backup suppressor activated after ESD diode clamping, absorbing residual 10/1000 µs tail energy.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VWM (94 V) and VC (152 V), but SMB package (DO-214AA); 600 W PPPM rating. | Larger footprint (4.58 mm × 3.94 mm vs. SMA's 4.50 mm × 2.79 mm); higher thermal mass supports longer surge duration. | Select when board space allows larger package and higher single-pulse energy tolerance is required. |
| 1.5KE110CA | Through-hole DO-201 package; identical VWM/VC specs but 1500 W PPPM (10/1000 µs) and higher IPPM (13.3 A). | Not SMT-compatible; requires wave soldering; suited for legacy or high-reliability through-hole designs. | Choose only for through-hole assembly or where 1.5 kW surge rating justifies manual placement and larger board area. |
Compared with P4SMA110CA-M3/5A, SMBJ110CA offers greater pulse power headroom in a slightly larger SMT package, while 1.5KE110CA provides significantly higher energy handling in a non-SMT form factor-neither is pin-compatible, but both serve overlapping protection roles with trade-offs in layout, assembly, and surge margin.

FAQ
What is the clamping voltage of P4SMA110CA-M3/5A at its rated peak pulse current?
The P4SMA110CA-M3/5A exhibits a maximum clamping voltage (VC) of 152 V when subjected to its specified peak pulse current of 2.0 A with a 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and represents the upper voltage limit imposed on protected circuitry during standardized surge events-critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P4SMA110CA-M3/5A suitable for automotive applications?
Yes, P4SMA110CA-M3/5A is qualified to AEC-Q101 when ordered with the HM3 suffix (e.g., P4SMA110CAHM3_A/I), and the M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance. While the base P4SMA110CA-M3/5A is commercial-grade, its thermal range (–65 °C to +150 °C) and robust surge performance make it suitable for non-safety-critical automotive subsystems when validated per end-system requirements.
How does the bidirectional design of P4SMA110CA-M3/5A affect its PCB layout?
The bidirectional nature of P4SMA110CA-M3/5A eliminates polarity marking-no cathode band is present, and either terminal may connect to signal or ground. Layout requires symmetric 5.0 mm × 5.0 mm copper pads per lead per Vishay's thermal recommendation, with no orientation dependency. This simplifies routing on differential lines and reduces BOM complexity versus unidirectional pairs.
What is the maximum reverse leakage current for P4SMA110CA-M3/5A at its standoff voltage?
The maximum reverse leakage current (ID) for P4SMA110CA-M3/5A is 1.0 µA when biased at its rated standoff voltage (VWM) of 94.0 V and tested at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and minimizes standby power loss in battery-operated systems-verified per Table on page 2 of Vishay document 88367.
Can P4SMA110CA-M3/5A be used in place of a unidirectional TVS like P4SMA110A-M3/5A?
No-P4SMA110CA-M3/5A is strictly bidirectional and lacks polarity marking, whereas P4SMA110A-M3/5A is unidirectional with a cathode band. Substitution would compromise protection on DC-biased lines (e.g., 12 V power rails), where unidirectional clamping prevents forward conduction during normal operation. Use P4SMA110CA-M3/5A only where symmetrical AC or differential transient suppression is required.
