Product details
Overview
P4SMA10CA-E3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 10 V standoff voltage (VWM), 11.1 V minimum breakdown voltage (VBR), 14.5 V maximum clamping voltage (VC) at 27.6 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P4SMA10CA-E3/61 datasheet, P4SMA10CA-E3/61 pinout, P4SMA10CA-E3/61 application, or P4SMA10CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.31), AEC-Q101 qualification eligibility (via HE3/HM3 variants), RoHS-compliant matte tin terminations, and MSL Level 1 moisture sensitivity rating.
Technical Context
The P4SMA10CA-E3/61 operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), enabling protection against ESD, lightning-induced surges, and inductive switching spikes.
Thermal performance is defined by RθJA = 120 °C/W and RθJL = 30 °C/W, with derating above 25 °C ambient per Figure 2. It supports repetitive surge duty cycles up to 0.01 % (300 W above 91 V), and meets UL 497B recognition (QVGQ2) for telecom and industrial protector classification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 10 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 11.1 V min - Voltage at which device enters avalanche breakdown at 1 mA test current; ensures reliable turn-on during transients. |
| VC (Clamping Voltage) | 14.5 V max at 27.6 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Surge energy handling capacity under standard 10/1000 µs waveform; validates robustness against IEC 61000-4-5 Level 3/4 threats. |
| ID (Reverse Leakage) | 10 µA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; enables operation in under-hood automotive and industrial environments. |
| Package | SMA (DO-214AC) - Surface-mount outline with 5.0 mm × 5.0 mm copper pad thermal design; supports automated placement and reflow soldering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Higher PPPM (600 W), larger SMB (DO-214AA) package, 12.2 V VBR min, 17.0 V VC max at 35.3 A | Preferred where higher surge margin is required and PCB space allows larger footprint | Select when system-level surge testing exceeds 400 W or thermal dissipation demands lower RθJA |

FAQ
What is the clamping voltage of P4SMA10CA-E3/61 at its rated peak pulse current?
The P4SMA10CA-E3/61 has a maximum clamping voltage (VC) of 14.5 V at 27.6 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of the Vishay datasheet 88367, and defines the upper voltage limit imposed on protected circuitry during surge events. The P4SMA10CA-E3/61 maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is P4SMA10CA-E3/61 suitable for automotive applications?
The base P4SMA10CA-E3/61 is RoHS-compliant and commercial-grade; however, Vishay offers AEC-Q101 qualified versions under ordering codes P4SMA10CAHE3_A and P4SMA10CAHM3_A (with revision suffixes). These variants undergo stress testing per AEC-Q101 and are intended for automotive use. The P4SMA10CA-E3/61 itself is not AEC-Q101 qualified but shares identical electrical and thermal characteristics with the qualified variants.
What is the thermal resistance of P4SMA10CA-E3/61, and how does it affect PCB layout?
The P4SMA10CA-E3/61 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, as specified in the "Thermal Characteristics" table. To maintain safe junction temperatures under repetitive surge conditions, PCB layout must replicate this pad area and avoid excessive trace length or isolation. The P4SMA10CA-E3/61 relies on copper thermal mass-not internal heatsinking-for transient energy dissipation.
Does P4SMA10CA-E3/61 have polarity markings, and how is it installed on the PCB?
No, the P4SMA10CA-E3/61 is a bidirectional TVS diode and carries no polarity marking on its SMA (DO-214AC) package. Unlike unidirectional variants (e.g., P4SMA10A), it functions identically regardless of orientation on the PCB. Installation requires no anode/cathode alignment-both terminals are functionally symmetric-and the device clamps transients equally in either direction, simplifying layout and assembly for differential or floating signal lines.
What is the maximum reverse leakage current of P4SMA10CA-E3/61 at its standoff voltage?
The P4SMA10CA-E3/61 exhibits a maximum reverse leakage current (ID) of 10 µA at its 10 V standoff voltage (VWM), measured at 25 °C ambient per the "Electrical Characteristics" table. This low leakage ensures minimal loading on high-impedance sensor outputs or battery-powered circuits. The P4SMA10CA-E3/61 maintains leakage below 50 µA up to 85 °C, supporting stable operation in extended-temperature industrial environments.
