Product details
Overview
P4SMA10CA-E3/5A from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor (TVS) designed for clamping inductive and lightning-induced transients across signal and power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 27.6 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), making it suitable for protecting MOSFETs, sensor interfaces, and IC power rails in industrial and automotive electronics.
For engineers reviewing the P4SMA10CA-E3/5A datasheet, P4SMA10CA-E3/5A pinout, P4SMA10CA-E3/5A application, or P4SMA10CA-E3/5A equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.45), AEC-Q101 qualification eligibility (via HE3/HM3 variants), thermal resistance (RθJA = 120 °C/W), and SMA (DO-214AC) package compatibility with automated SMT assembly.
Technical Context
The P4SMA10CA-E3/5A operates as a bidirectional avalanche diode, symmetrically clamping voltage surges in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the 10/1000 µs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5.
It delivers 400 W peak pulse power up to 91 V and derates to 300 W above that threshold, with thermal performance governed by RθJA = 120 °C/W and RθJL = 30 °C/W. The device is rated for TJ = -65 °C to +150 °C and meets MSL Level 1 (260 °C reflow peak), supporting high-reliability PCB assembly.
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) | 10.5 V min / 11.6 V max at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on under transient stress. |
| VC (Clamping Voltage) | 14.5 V at IPPM = 27.6 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for downstream component survivability. |
| PPPM (Peak Pulse Power) | 400 W (≤91 V), 300 W (>91 V) - Surge energy handling capacity; determines protection level against common ESD and lightning surges. |
| 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 ambient environments. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement for thermal management. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Bidirectional configuration has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity surge) | One terminal of symmetrical avalanche junction; conducts when voltage falls below -VBR. |
| Anode | Transient current entry (positive polarity surge) | Same physical terminal serves as cathode during positive surges due to bidirectional symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 400 W peak pulse power (10/1000 µs) | Supports robust immunity to IEC 61000-4-5 Level 3 (1 kV line-to-ground) surges in industrial equipment. |
| AEC-Q101 qualification path | HE3/HM3 variants available for automotive applications; P4SMA10CA-E3/5A shares identical electrical specs and package. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard 260 °C reflow without baking, reducing manufacturing overhead. |
| Glass passivated junction | Ensures stable VBR over temperature and lifetime, minimizing parameter drift in harsh environments. |
Applications

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 600 W PPPM rating; larger SMB (DO-214AA) package; 12.5 V VC at 32.4 A IPPM. | Better suited for higher-energy surges but requires larger PCB footprint and different pad layout. | Select when system-level surge tests exceed 400 W or when thermal margin must be increased via larger copper area. |
| 1.5KE10CA | Through-hole TO-218 package; 1500 W PPPM; 14.5 V VC at 103 A IPPM; higher leakage (50 µA). | Designed for board-level primary protection rather than point-of-load clamping; not SMT-compatible. | Choose for legacy through-hole designs or where highest single-pulse energy absorption is required, accepting manual assembly cost. |
Compared with SMBJ10CA and 1.5KE10CA, the P4SMA10CA-E3/5A provides optimal balance of compact SMA packaging, 400 W surge handling, and low-profile automated assembly-making it ideal for space-constrained, high-volume consumer and industrial PCBs where moderate surge levels dominate.

FAQ
What is the clamping voltage of the P4SMA10CA-E3/5A under a 10/1000 µs surge?
The P4SMA10CA-E3/5A exhibits a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 27.6 A under the standardized 10/1000 µs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during transient events, directly enabling safe operation of 12 V–15 V logic and interface ICs.
Is the P4SMA10CA-E3/5A suitable for automotive applications?
The P4SMA10CA-E3/5A itself is a commercial-grade part (E3 suffix), but it belongs to the AEC-Q101-qualified P4SMA family. Automotive-grade versions-P4SMA10CAHE3_A and P4SMA10CAHM3_A-are functionally identical and share the same electrical characteristics, package, and pinout. Engineers designing for automotive use should specify those HE3/HM3 variants to ensure qualification compliance.
Does the P4SMA10CA-E3/5A have polarity markings?
No, the P4SMA10CA-E3/5A does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., P4SMA10A), which feature a cathode band, the CA-suffixed version uses a symmetrical junction structure and is intended for applications where voltage transients may occur in either polarity-eliminating orientation constraints during placement.
What is the thermal resistance of the P4SMA10CA-E3/5A, and how does it affect layout?
The P4SMA10CA-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the recommended 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 allocate adequate copper area and avoid excessive trace length between the device and ground/power planes.
How does the P4SMA10CA-E3/5A compare to the P4SMA10A in terms of functionality?
The P4SMA10CA-E3/5A is bidirectional, while the P4SMA10A is unidirectional. Both share identical VWM (10 V), VBR (10.5–11.6 V), and VC (14.5 V) ratings, but the CA variant clamps symmetrically in both directions-making it appropriate for AC signals, floating buses, or dual-rail supplies. The unidirectional P4SMA10A includes a cathode band and conducts only in reverse bias, requiring correct orientation.
