Product details
Overview
P4SMA62C from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with 50.2V working stand-off voltage, 55.8–68.2V breakdown voltage at 1mA, and 89.0V maximum clamping voltage at 4.7A peak pulse current. It protects DC/DC converters and SMPS inputs against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA62C datasheet, P4SMA62C pinout, P4SMA62C application, or P4SMA62C equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, leakage current at operating bias, thermal derating above 25°C, and compliance with automotive surge immunity standards.
Technical Context
The P4SMA62C operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR range (55.8–68.2V). Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1µA at 50.2V), while fast response (<1.0ps) enables suppression of nanosecond-scale ESD and switching surges.
Designed for surface-mount assembly on power rails, it handles 400W peak pulse power under 10/1000µs waveform and supports 40A non-repetitive forward surge. Junction temperature range is –55°C to +150°C, with moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 50.2 V - Maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for system rail voltage compatibility. |
| VBR @ IT=1mA | 55.8–68.2 V - Breakdown voltage range defining turn-on threshold; used to verify margin over VWM and ensure reliable clamping onset. |
| VC @ IPPM=4.7A | 89.0 V - Clamping voltage during 10/1000µs surge; determines maximum stress imposed on downstream circuitry. |
| PPPM | 400 W - Peak pulse power rating; defines energy-handling capability for standardized transient waveforms (e.g., ISO 7637-2). |
| IR @ VWM | <1 µA - Reverse leakage at stand-off voltage; critical for low-power standby circuits and battery-backed systems. |
| TJ max | +150 °C - Maximum junction temperature; sets thermal design limits for PCB copper area and ambient operating conditions. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-diode configuration with cathode band marking. Matte tin-plated leads, UL 94V-0 molding compound, 0.060g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive transients when used in reverse-biased protection configuration. |
| Cathode | Reverse-bias clamping terminal | Connected to protected line (e.g., 48V rail); avalanches into conduction when line voltage exceeds VBR, shunting surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| Fast response time <1.0 ps | Enables effective suppression of high-frequency ESD events and MOSFET switching-induced spikes before sensitive ICs are damaged. |
| Meets ISO 7637-2 Pulse 1/2a/2b/3a/3b | Validated for automotive load-dump and supply-line transient immunity testing without external filtering or derating. |
| Moisture sensitivity level 1 | Allows unlimited floor life and standard reflow without baking, simplifying SMT manufacturing flow. |
Applications
| Switching Mode Power Supply (SMPS) | On-board DC/DC Converter |
|---|---|
Use Scenario: Input stage of 48V-to-12V isolated flyback converter subjected to load dump transients in industrial control cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS placed between primary-side input rail and chassis ground to clamp surges before they reach the controller IC and bulk capacitor. Use Value: Limits peak voltage to 89.0V during 400W transients, preserving 100V-rated input capacitors and preventing controller latch-up. | Use Scenario: 24V-to-3.3V buck converter powering FPGA I/O banks in programmable logic controllers. IC Role / Device Role / Timing Role: TVS mounted directly at DC/DC input pins to suppress coupling from adjacent motor drive traces and relay coil flyback. Use Value: Sub-1µA leakage avoids loading low-quiescent-current enable circuits; DO-214AC footprint allows placement within 2mm of input pads for minimal loop inductance. |
| Lighting Application | Adapters |
Use Scenario: Constant-current LED driver in outdoor streetlight housing exposed to lightning-induced surges on AC mains input. IC Role / Device Role / Timing Role: Secondary-side TVS across output terminals to protect LED strings and current-sense amplifier from reflected transients. Use Value: 89.0V clamping ensures LED string forward voltage (typically 72V for 20×3.6V LEDs) remains below destructive threshold during surge events. | Use Scenario: Universal AC/DC adapter for medical monitoring equipment requiring reinforced isolation and low EMI. IC Role / Device Role / Timing Role: TVS on secondary-side 5V/12V output rails to prevent transient coupling into USB or RS-232 interfaces during hot-plug events. Use Value: RoHS-compliant and halogen-free construction meets IEC 61249-2-21 requirements for patient-connected devices; <1µA leakage avoids false resets in microcontroller supervisors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A (Bourns) | DO-214AA (SMB) package; 64V VBR min/max tighter (60.8–67.2V); 6.5A IPPM; same 400W rating. | Larger footprint (SMB vs SMA) requires PCB layout change; higher IPPM suits higher-energy surges but increases cost. | Select SMBJ64A only if board space permits larger package and higher clamping margin is needed beyond 89.0V. |
| 1.5SMC62A (ON Semiconductor) | DO-214AB (SMC) package; 62V nominal VBR; 6.5A IPPM; 1500W peak power rating. | Substantially larger SMC package and higher power rating make it over-specified for 400W use cases; not drop-in compatible. | Choose 1.5SMC62A only for designs requiring >400W surge handling or where SMC footprint is already standardized. |
Compared with SMBJ64A and 1.5SMC62A, the P4SMA62C offers optimal balance of compact DO-214AC footprint, precise 50.2V VWM, and verified ISO 7637-2 compliance-making it ideal for space-constrained industrial and automotive power modules where layout reuse and thermal efficiency are prioritized.

FAQ
What is the polarity configuration of the P4SMA62C?
The P4SMA62C is a unidirectional TVS diode, configured with anode and cathode terminals marked by a cathode band on the DO-214AC package body. It conducts in forward bias and clamps in reverse bias above VBR; the P4SMA62CA variant is bidirectional. Polarity must be observed during PCB layout to ensure correct surge shunting path to ground.
Does the P4SMA62C meet automotive surge immunity standards?
Yes, the P4SMA62C meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements per manufacturer documentation. Its 400W peak pulse rating, 89.0V clamping voltage, and –55°C to +150°C operating range make it suitable for 12V/24V automotive subsystems including body control modules and infotainment power rails.
What is the maximum clamping voltage of the P4SMA62C under standard test conditions?
The maximum clamping voltage of the P4SMA62C is 89.0V at 4.7A peak pulse current using the 10/1000µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events-critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P4SMA62C RoHS and halogen-free compliant?
Yes, the P4SMA62C is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and matte tin-plated leads comply with J-STD-002 solderability requirements-supporting lead-free reflow processes and environmental compliance for global electronics manufacturing.
How does the P4SMA62C compare to the P4SMA62A variant?
The P4SMA62C has a VBR range of 55.8–68.2V at 1mA, while the P4SMA62A has a tighter 58.9–65.1V range and slightly lower 85.0V clamping voltage at 5.0A. The P4SMA62C offers broader breakdown tolerance and is preferred where system-level voltage variation or temperature drift demands wider VBR margin; both share identical DO-214AC package and 400W rating.
