Product details
Overview
P4SMA62CA-M3/5A 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 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA, 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P4SMA62CA-M3/5A datasheet, P4SMA62CA-M3/5A pinout, P4SMA62CA-M3/5A application, or P4SMA62CA-M3/5A equivalent, key selection criteria include bidirectional clamping capability, low incremental surge resistance, AEC-Q101 qualification (via HM3 suffix), halogen-free RoHS compliance, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance in forward and reverse directions. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low Rsurge minimizes voltage overshoot during transient events.
The device is rated for 400 W peak pulse power (10/1000 µs) up to TA = 25 °C, derating linearly above that temperature per Figure 2; thermal resistance is 120 °C/W junction-to-ambient (RθJA) on minimum recommended pad layout, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse working voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at IT = 1 mA - Confirmed breakdown range ensuring reliable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 85.0 V at IPPM = 4.7 A - Peak voltage seen by protected circuit during 10/1000 µs transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capacity under standardized surge waveform; enables protection against IEC 61000-4-5 Level 3/4 surges. |
| IPPM (Peak Pulse Current) | 4.7 A - Maximum non-repetitive surge current the device can safely divert without degradation. |
| TJmax | 150 °C - Maximum junction temperature defining thermal design limits for PCB layout and ambient conditions. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline with 5.28 mm length, 4.50 mm width, and 2.29 mm height; compatible with JEDEC MS-012. |
Pinout & Package

|---|---|
|
Use Scenario: Protection of gate drivers and feedback signal lines against voltage spikes caused by relay coil de-energization or PWM switching noise. IC Role / Device Role / Timing Role: Bidirectional TVS placed across isolated signal paths or low-voltage DC rails to clamp transients before they reach sensitive analog front-ends or microcontrollers. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V logic inputs by limiting transient excursions to ≤85.0 V, preserving system uptime and reducing field failure rates. |
Use Scenario: ESD and load-dump suppression on LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control modules. IC Role / Device Role / Timing Role: Standoff-rated transient suppressor mounted directly at connector entry points or sensor harness interfaces to absorb fast-rising ESD pulses and slow-rising battery dump energy. Use Value: Maintains signal integrity under ISO 10605 (30 kV air discharge) and ISO 7637-2 (Pulse 5a) test conditions without requiring additional series impedance or filtering. |
| Telecom Power Supply Rails | Consumer USB-C Port Protection |
|
Use Scenario: Secondary-side overvoltage protection on 12 V or 24 V telecom DC distribution buses exposed to hot-swap and backplane transients. IC Role / Device Role / Timing Role: Parallel-connected TVS across regulated output rails to shunt surge energy away from downstream DC/DC converters and PMICs. Use Value: Limits rail overshoot to <85 V during 10/1000 µs surges, preventing overvoltage shutdown or internal FET avalanche in point-of-load regulators. |
Use Scenario: Bidirectional transient suppression on USB-C CC and VCONN lines subject to accidental 20 V misconnection or electrostatic discharge. IC Role / Device Role / Timing Role: Low-capacitance TVS placed adjacent to USB-C receptacle to clamp both positive and negative transients without distorting high-speed data signals. Use Value: Provides sub-nanosecond response with <10 pF typical junction capacitance (per Fig. 4 at VWM), avoiding signal integrity degradation on sideband use (SBU) or configuration channel lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher VWM (55.1 V), same VC (85.0 V), larger SMB package (DO-214AA), 600 W PPPM. | Requires larger PCB area; better suited for higher-energy surges where board space permits. | Select when higher surge margin is needed and footprint constraints allow SMB size. |
| 1.5SMC68CA | Same VWM/VBR range, 1500 W PPPM, larger SMC (DO-214AB) package, higher IPPM (21.9 A). | Overkill for low-energy signal-line protection; intended for primary-side AC input or bulk DC rail clamping. | Choose only for high-energy applications where P4SMA62CA-M3/5A's 400 W rating is insufficient. |
Compared with SMBJ64CA and 1.5SMC68CA, the P4SMA62CA-M3/5A offers optimal balance of compact SMA footprint, precise 53.0 V standoff, and sufficient 400 W surge handling for secondary-side and signal-level protection - making it preferred for space-constrained industrial and automotive modules where board real estate and thermal mass are limited.

FAQ
What is the clamping voltage of the P4SMA62CA-M3/5A under a 10/1000 µs surge?
The P4SMA62CA-M3/5A has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88367 and defines the upper voltage limit imposed on protected circuitry during transient events. The P4SMA62CA-M3/5A maintains this clamping performance bidirectionally due to its symmetrical construction.
Is the P4SMA62CA-M3/5A suitable for automotive applications?
The P4SMA62CA-M3/5A itself carries the M3 suffix (halogen-free, RoHS-compliant commercial grade), not the HM3 automotive-qualified variant. However, the P4SMA62CA-HM3/5A is AEC-Q101 qualified and shares identical electrical specs. For automotive use, specify the HM3 version; the P4SMA62CA-M3/5A is appropriate for industrial and consumer applications where AEC-Q101 is not mandated.
What is the standoff voltage (VWM) of the P4SMA62CA-M3/5A?
The standoff voltage (VWM) of the P4SMA62CA-M3/5A is 53.0 V - the maximum DC or RMS voltage the device can withstand continuously without entering breakdown. This value appears in the Electrical Characteristics table on page 2 of Vishay document 88367 and ensures safe operation below the 58.9–65.1 V breakdown range. The P4SMA62CA-M3/5A must be selected so that VWM exceeds the normal operating voltage of the protected line by ≥10 %.
Does the P4SMA62CA-M3/5A have polarity markings?
No, the P4SMA62CA-M3/5A does not have polarity markings because it is a bidirectional TVS diode. As stated in the Mechanical Data section, "no marking on bidirectional types." Its symmetrical terminal structure allows installation in either orientation, simplifying PCB layout and eliminating risk of reverse placement - a key advantage over unidirectional variants like P4SMA62A-M3/5A, which feature a cathode band.
What is the thermal resistance of the P4SMA62CA-M3/5A?
The P4SMA62CA-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on the minimum recommended pad layout (0.2" × 0.2" copper pads per terminal), per Thermal Characteristics table on page 3 of Vishay document 88367. This value informs thermal design margins - for example, at 3.3 W steady-state dissipation, junction temperature rise would be ~396 °C above ambient, confirming that the device is intended for transient-only (not continuous) power dissipation.
