Product details
Overview
P4SMA100CA-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 100 V standoff voltage (VWM), 115 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P4SMA100CA-E3/61 datasheet, P4SMA100CA-E3/61 pinout, P4SMA100CA-E3/61 application, or P4SMA100CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), and compliance with UL 497B for protector classification.
Technical Context
The P4SMA100CA-E3/61 operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for protecting sensitive downstream ICs from ESD and inductive switching spikes.
Rated for 400 W peak pulse power (derated to 300 W above 91 V), it delivers 137 V clamping at 2.2 A IPPM under 10/1000 µs waveform while maintaining ≤1.0 µA reverse leakage at 85.5 V (VWM). Junction temperature range spans –65 °C to +150 °C, supporting operation in harsh automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Confirmed avalanche conduction threshold in both directions |
| VC (Clamping Voltage) | 137 V at 2.2 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs transient |
| PPPM (Peak Pulse Power) | 400 W - Sustains 10/1000 µs surges without failure when mounted on 5.0 mm × 5.0 mm copper pads |
| ID (Reverse Leakage) | ≤1.0 µA at 85.5 V - Ensures minimal standby power loss and signal integrity in high-impedance lines |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient; dictates derating above 25 °C ambient |
| Package | SMA (DO-214AC) - Surface-mount footprint compatible with automated placement and reflow soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Higher 600 W PPPM; larger SMB (DO-214AA) package; RθJA = 85 °C/W | Better suited for higher-energy surges but requires larger board area | Select when system-level surge testing exceeds IEC 61000-4-5 Level 4 and PCB layout allows SMB footprint |
| 1.5KE100CA | Through-hole TO-218 package; 1500 W PPPM; higher VC (154 V); slower response due to lead inductance | Used in legacy power supply input stages where manual assembly is acceptable | Choose only for cost-sensitive, non-automated production or where higher clamping voltage is tolerable |
Compared with SMBJ100CA and 1.5KE100CA, the P4SMA100CA-E3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and verified 400 W surge handling - making it preferred for space-constrained automotive and industrial PCBs requiring automated assembly.

FAQ
What is the polarity configuration of P4SMA100CA-E3/61?
The "CA" suffix denotes bidirectional operation: P4SMA100CA-E3/61 has no cathode band or polarity marking and functions identically in both voltage polarities. This makes it ideal for AC signal lines, differential buses like CAN or RS-485, and floating power rails where polarity reversal may occur during transients.
Is P4SMA100CA-E3/61 qualified for automotive applications?
Yes - P4SMA100CA-E3/61 is AEC-Q101 qualified per Vishay's documentation (Revision 09-Jan-2024, Doc. 88367), confirming reliability for automotive use including under-hood and ADAS sensor modules. The "E3" suffix indicates RoHS-compliant commercial grade; AEC-Q101 validation applies to the base P4SMA100CA device family.
What is the maximum clamping voltage of P4SMA100CA-E3/61 under surge conditions?
The maximum clamping voltage (VC) of P4SMA100CA-E3/61 is 137 V at 2.2 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value is measured with the device mounted on 0.2″ × 0.2″ (5.0 mm × 5.0 mm) copper pads per JEDEC guidelines and defines the upper voltage limit imposed on protected circuitry during transient events.
Does P4SMA100CA-E3/61 meet UL safety certification requirements?
Yes - P4SMA100CA-E3/61 is Underwriters Laboratory (UL) recognized under standard UL 497B for protectors (file E136766), covering both unidirectional and bidirectional configurations. This certification validates its suitability for use in telecom, industrial, and consumer equipment requiring third-party safety compliance.
What is the thermal resistance of P4SMA100CA-E3/61, and how does it affect derating?
P4SMA100CA-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W. At ambient temperatures above 25 °C, its peak pulse power must be linearly derated - e.g., at 75 °C ambient, maximum PPPM drops to ~200 W. Derating curves are provided in Figure 2 of the Vishay datasheet (Doc. 88367).
