Product details
Overview
P4SMA100CA-E3/5A 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 100 V standoff voltage (VWM), 105 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 2.2 A peak pulse current, and 400 W peak pulse power rating with a 10/1000 µs waveform - suitable for protecting MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the P4SMA100CA-E3/5A datasheet, P4SMA100CA-E3/5A pinout, P4SMA100CA-E3/5A application, or P4SMA100CA-E3/5A equivalent, key selection criteria include bidirectional clamping capability, SMA (DO-214AC) package compatibility with automated SMT assembly, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
The P4SMA100CA-E3/5A operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 µA at 85.5 V), while the 10/1000 µs waveform rating reflects standardized surge immunity testing per ANSI/IEEE C62.35.
Thermally, it sustains operation up to 150 °C junction temperature and exhibits RθJL = 30 °C/W junction-to-lead resistance, enabling reliable performance on standard 5.0 mm × 5.0 mm copper pads. The device meets MSL Level 1 per J-STD-020 and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 137 V at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for downstream component survivability. |
| PPPM (Peak Pulse Power) | 400 W - Surge energy handling capacity under standardized 10/1000 µs waveform; derates above 25 °C per Fig. 2. |
| ID (Reverse Leakage) | <1 µA at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max. | 150 °C - Maximum allowable junction temperature; supports operation in enclosed industrial enclosures without forced cooling. |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient; informs board-level thermal design requirements for sustained power dissipation. |
Pinout & Package
Package: SMA (DO-214AC) - surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same VWM (85.5 V) and VC (137 V), but higher PPPM (600 W); SMB package (DO-214AA), 2.5 mm wider body | Requires PCB pad revision due to larger footprint; better suited for higher-energy surges in DIN rail-mounted equipment | Select when >400 W surge margin is needed and board space allows SMB package; not drop-in compatible. |
| 1.5KE100CA | Same VWM/VC specs, but through-hole DO-15 package; 1.5 kW peak power rating with 10/1000 µs waveform | Not suitable for automated SMT lines; used in legacy designs or prototyping where hand-soldering is acceptable | Choose only for repair, backward compatibility, or manual assembly; incompatible with P4SMA100CA-E3/5A's SMT process flow. |
Compared with SMBJ100CA and 1.5KE100CA, the P4SMA100CA-E3/5A delivers optimal balance of SMT manufacturability, thermal performance (RθJA = 120 °C/W), and compact DO-214AC footprint - making it preferred for space-constrained, high-volume industrial and telecom modules where reflow compatibility and MSL Level 1 handling are essential.

FAQ
What is the clamping voltage of P4SMA100CA-E3/5A at its rated peak pulse current?
The P4SMA100CA-E3/5A has a maximum clamping voltage (VC) of 137 V at a peak pulse current (IPPM) of 2.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the highest voltage imposed on the protected circuit during standardized surge testing. The P4SMA100CA-E3/5A maintains this clamping performance across its specified operating temperature range.
Is P4SMA100CA-E3/5A suitable for automotive applications?
The base P4SMA100CA-E3/5A is RoHS-compliant and commercial-grade; however, the AEC-Q101 qualified version is designated as P4SMA100CAHE3_A or P4SMA100CAHM3_A (with suffix "HE3" or "HM3"). These variants undergo stress testing per AEC-Q101 and are approved for automotive body electronics. The P4SMA100CA-E3/5A itself is not AEC-Q101 qualified unless ordered with HE3/HM3 suffixes.
What does the "CA" suffix indicate in P4SMA100CA-E3/5A?
The "CA" suffix in P4SMA100CA-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 exhibit identical electrical characteristics in either polarity, making them ideal for AC signal lines and differential buses.
What is the thermal resistance of P4SMA100CA-E3/5A, and how does it affect layout?
The P4SMA100CA-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repetitive surge conditions, PCB layout must provide adequate copper area and avoid excessive trace length. The P4SMA100CA-E3/5A also features RθJL = 30 °C/W, supporting efficient heat transfer to PCB copper planes.
Does P4SMA100CA-E3/5A meet any safety certifications?
Yes, the P4SMA100CA-E3/5A is Underwriters Laboratory (UL) recognized under file E136766 for both unidirectional and bidirectional devices, classified per UL 497B for signal and power line protectors. It also meets MSL Level 1 per J-STD-020 and is RoHS-compliant with halogen-free options available via M3 suffix. The P4SMA100CA-E3/5A carries UL QVGQ2 recognition for surge protector classification.
