Product details
Overview
P4SMA62CA-E3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating (10/1000 µs waveform). It is widely deployed to safeguard MOSFETs, ICs, and sensor signal lines against ESD and inductive switching transients in industrial and automotive electronics.
For engineers reviewing the P4SMA62CA-E3/5A datasheet, P4SMA62CA-E3/5A pinout, P4SMA62CA-E3/5A application, or P4SMA62CA-E3/5A equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal resistance data, and validated alternative parts - all aligned with Vishay's official P4SMA Series specification document 88367 (Rev. 09-Jan-2024).
Technical Context
The P4SMA62CA-E3/5A operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±62 V in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM = 53.0 V), while its low incremental surge resistance enables rapid energy diversion during transient events.
Thermally, it exhibits RθJA = 120 °C/W (junction-to-ambient, on minimum pad layout) and RθJL = 30 °C/W (junction-to-lead), supporting reliable operation up to TJ = +150 °C. It meets J-STD-020 MSL Level 1 and is RoHS-compliant (E3 suffix), with optional AEC-Q101 qualification available under HE3/HM3 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 58.9–65.1 V at 1.0 mA test current - defines precise voltage threshold where avalanche conduction begins in both directions |
| Stand-off Voltage VWM | 53.0 V - maximum continuous reverse working voltage before significant leakage; sets safe operating margin below VBR |
| Clamping Voltage VC | 85.0 V at 4.7 A (10/1000 µs) - actual voltage seen by protected circuit during worst-case surge; critical for downstream component survivability |
| Peak Pulse Power PPPM | 400 W (10/1000 µs) - energy-handling capacity under standardized surge waveform; derates to 300 W above 91 V |
| Maximum Leakage ID | <1.0 µA at VWM = 53.0 V - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Junction Temperature Range | −65 °C to +150 °C - supports operation in harsh environments including under-hood automotive and industrial control cabinets |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement for thermal performance |
Pinout & Package
SMA (DO-214AC) package: low-profile, molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during positive surge | One side of symmetrical PN junction; forms clamping path with cathode during either polarity transient |
| Cathode | Current entry terminal during negative surge | Complementary terminal to anode; enables bidirectional conduction without external polarity assignment |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables protection against high-energy transients like ISO 7637-2 pulse 1/2a/5a in automotive systems without derating |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on protected ICs - e.g., keeps 3.3 V or 5 V logic lines safely within absolute maximum ratings |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without moisture sensitivity concerns or baking requirements |
| AEC-Q101 qualified variant available | Validated for automotive-grade reliability (HTOL, TC, HTRB) - essential for ADAS, body control, and infotainment modules |
| Glass passivated junction | Ensures long-term parameter stability and low leakage drift across temperature and lifetime |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA (Bourns) | Higher VBR (60.8–67.2 V), same SMA footprint but SMB package (DO-214AA); 600 W PPPM rating | Offers higher surge margin but requires PCB layout change due to larger SMB package and different pad geometry | Select when higher 600 W surge handling is required and board space allows SMB footprint |
| 1.5KE68CA (ON Semiconductor) | Through-hole DO-15 package; 68 V VBR, 87.1 V VC at 5.8 A; 1500 W PPPM but incompatible mounting | Not suitable for automated SMT production; intended for prototyping or legacy through-hole designs | Choose only for manual assembly or retrofit scenarios where SMT is unavailable |
Compared with P4SMA62CA-E3/5A, SMBJ64CA provides greater surge headroom in a physically larger package, while 1.5KE68CA trades mountability for raw power rating - making P4SMA62CA-E3/5A the optimal balance of SMT compatibility, precision clamping, and 400 W protection for space-constrained industrial and automotive PCBs.

FAQ
What is the exact breakdown voltage range for P4SMA62CA-E3/5A?
The P4SMA62CA-E3/5A has a specified breakdown voltage (VBR) range of 58.9 V to 65.1 V at a test current of 1.0 mA, per Vishay's official datasheet (Document Number 88367, Rev. 09-Jan-2024). This bidirectional tolerance ensures consistent clamping symmetry and is measured under controlled conditions with traceable calibration. The P4SMA62CA-E3/5A maintains this specification across its full operating temperature range.
Does P4SMA62CA-E3/5A require polarity-aware PCB layout?
No - the P4SMA62CA-E3/5A is a bidirectional TVS diode and carries no polarity marking on its SMA (DO-214AC) package. Its internal structure provides identical clamping behavior for both positive and negative transients, eliminating orientation constraints during placement. This simplifies SMT assembly and reduces risk of misorientation-related field failures. The P4SMA62CA-E3/5A is explicitly designated for bidirectional use via the "CA" suffix in its part number.
What is the maximum clamping voltage of P4SMA62CA-E3/5A under surge conditions?
The P4SMA62CA-E3/5A clamps to a maximum of 85.0 V when subjected to a 4.7 A peak pulse current with a 10/1000 µs waveform, as confirmed in Table 1 of Vishay's P4SMA Series datasheet. This value represents the worst-case voltage imposed on protected circuitry during standardized surge testing and is critical for verifying compatibility with downstream IC absolute maximum ratings. The P4SMA62CA-E3/5A achieves this with a clamping ratio of approximately 1.33 relative to its nominal VBR.
Is P4SMA62CA-E3/5A suitable for automotive applications?
The base P4SMA62CA-E3/5A is RoHS-compliant and MSL Level 1 qualified but not AEC-Q101 certified. However, Vishay offers AEC-Q101-qualified versions under ordering codes such as P4SMA62CAHE3_A (7" reel) or P4SMA62CAHM3_A (13" reel), which undergo HTOL, temperature cycling, and HTRB validation. For production automotive use, specify the HE3 or HM3 suffix variants - the P4SMA62CA-E3/5A itself is appropriate for non-safety-critical commercial/industrial designs.
What thermal resistance values apply to P4SMA62CA-E3/5A in standard layout?
Per Vishay's datasheet, the P4SMA62CA-E3/5A exhibits a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Its junction-to-lead resistance (RθJL) is 30 °C/W. These values assume no additional heatsinking and define safe power derating curves - for example, at 75 °C ambient, the P4SMA62CA-E3/5A must be limited to ~1.8 W continuous dissipation to stay within its 150 °C TJ limit.
