Product details
Overview
P4SMA13CA-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 or power lines. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at 1 mA), 11.1 V maximum standoff voltage (VWM), and 18.2 V clamping voltage (VC) at 22 A peak pulse current under 10/1000 µs waveform - delivering 400 W peak pulse power capability for robust ESD and surge protection in compact consumer and industrial electronics.
For engineers reviewing the P4SMA13CA-E3/61 datasheet, P4SMA13CA-E3/61 pinout, P4SMA13CA-E3/61 application, or P4SMA13CA-E3/61 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified (via HE3/HM3 variants) bidirectional TVS with SMA (DO-214AC) package, low incremental surge resistance, and fast response time - critical for protecting MOSFETs, ICs, and sensor signal lines against inductive switching and lightning-induced surges.
Technical Context
The P4SMA13CA-E3/61 operates as a bidirectional avalanche diode, symmetrically clamping transient voltages above ±13 V in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while its 120 °C/W junction-to-ambient thermal resistance supports operation up to +150 °C junction temperature.
It delivers 400 W peak pulse power (10/1000 µs waveform) at 25 °C, derating linearly above TA = 25 °C per Figure 2, and sustains repetitive surges at 0.01% duty cycle. The device meets MSL Level 1 per J-STD-020 and is rated for 260 °C lead-free reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 12.4–13.7 V at 1 mA test current - defines precise clamping onset threshold in both directions |
| Standoff Voltage VWM | 11.1 V maximum - ensures no conduction during normal 12 V system operation |
| Clamping Voltage VC | 18.2 V at 22 A IPPM (10/1000 µs) - limits transient voltage seen by protected ICs |
| Peak Pulse Power PPPM | 400 W (10/1000 µs) - handles high-energy transients common in automotive and industrial environments |
| Package | SMA (DO-214AC) - surface-mount, low-profile package compatible with automated placement and IPC-7351B footprint |
| Operating Temperature | −65 °C to +150 °C - supports extended-range deployment in under-hood or industrial control applications |
| RoHS Compliance | E3 suffix - lead-free, halogen-free compliant per JEDEC J-STD-020 and Vishay material standards |
Pinout & Package
SMA (DO-214AC) package: molded plastic case with matte tin-plated leads, 0.208" × 0.157" body, cathode band omitted for bidirectional configuration. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; symmetrical with Cathode in bidirectional operation |

FAQ
What is the clamping voltage of P4SMA13CA-E3/61 at its rated peak pulse current?
The P4SMA13CA-E3/61 has a maximum clamping voltage (VC) of 18.2 V at 22 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" copper pads per Vishay's recommended layout, ensuring consistent thermal performance and repeatable clamping behavior in real-world PCB implementations.
Is P4SMA13CA-E3/61 suitable for automotive applications?
The P4SMA13CA-E3/61 itself is commercial-grade (E3 suffix), but Vishay offers AEC-Q101-qualified variants under HE3 and HM3 suffixes (e.g., P4SMA13CAHE3_A). For automotive use, specify the HE3/HM3 version - it undergoes additional stress testing per AEC-Q101 and supports junction temperatures up to +150 °C, meeting requirements for under-hood and body electronics.
How does the bidirectional design of P4SMA13CA-E3/61 affect its circuit placement?
The P4SMA13CA-E3/61 has no polarity marking and functions identically in both directions, so it can be placed across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs (CAN_H/CAN_L), AC-coupled audio lines, or ungrounded power rails. Unlike unidirectional TVS diodes, no orientation check is needed during placement, simplifying SMT assembly and reducing misorientation risk.
What is the maximum reverse leakage current for P4SMA13CA-E3/61 at its standoff voltage?
At the maximum standoff voltage (VWM = 11.1 V), the P4SMA13CA-E3/61 exhibits ≤1.0 µA reverse leakage current at 25 °C. This low leakage ensures negligible standby power loss and avoids false triggering in high-impedance circuits like sensor bias networks or microcontroller input pins, preserving system accuracy and battery life.
Can P4SMA13CA-E3/61 replace older P4SMA13C devices in existing designs?
Yes - P4SMA13CA-E3/61 is a direct replacement for legacy P4SMA13C parts, maintaining identical electrical specifications, SMA (DO-214AC) package dimensions, and thermal performance. The "A" denotes tighter VBR tolerance (±5% vs. ±10%), and "E3/61" confirms RoHS compliance and 7" tape-and-reel packaging, ensuring seamless drop-in compatibility in production and repair workflows.
