Product details
Overview
P4SMA62CAH from Taiwan Semiconductor is a bidirectional 400W surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with breakdown voltage 58.9–65.1 V at 1 mA test current, working stand-off voltage 53.0 V, clamping voltage 85.0 V at 5.0 A peak pulse current, and AEC-Q101 qualification for automotive-grade surge protection in DC/DC converters and power supplies.
For engineers reviewing the P4SMA62CAH datasheet, P4SMA62CAH pinout, P4SMA62CAH application, or P4SMA62CAH equivalent, key selection criteria include bidirectional clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, junction temperature range (−55°C to +150°C), moisture sensitivity level 1 compliance, and RoHS/halogen-free status for automotive and industrial PCB designs.
Technical Context
The P4SMA62CAH implements a glass-passivated silicon avalanche junction optimized for fast transient suppression with sub-1 ps response time and low leakage (<1 µA at 53.0 V). Its bidirectional configuration enables symmetric clamping in AC-coupled or floating signal lines without polarity constraints.
Designed per ANSI/IEEE C62.35, it delivers 400 W peak pulse power (10/1000 µs waveform) with thermal derating above 25°C ambient and supports automated SMT placement via matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 58.9 V / 65.1 V at 1 mA - defines minimum and maximum guaranteed breakdown threshold for reliable overvoltage triggering |
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC@IPPM | 85.0 V at 5.0 A - clamping voltage during 10/1000 µs surge, limiting downstream circuit stress |
| IR@VWM | <1 µA - ultra-low reverse leakage ensures minimal standby power loss in high-impedance circuits |
| PPPM | 400 W - peak pulse power handling capacity under standardized surge waveform |
| TJ range | −55°C to +150°C - extended junction temperature rating supports under-hood automotive and industrial environments |
| Package | DO-214AC (SMA) - industry-standard surface-mount outline with 0.060 g mass and UL 94V-0 molding compound |
Pinout & Package
DO-214AC (SMA) package: cathode band marked on one end; bidirectional operation means both terminals are functionally symmetric with no designated anode/cathode polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (marked side) | Cathode band indicator | Visual polarity marker for unidirectional variants; irrelevant for P4SMA62CAH due to bidirectional symmetry |
| Terminal 2 (opposite end) | Second terminal | Electrically identical to Terminal 1; forms symmetrical clamping path in either direction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress-test requirements including temperature cycling, HTRB, and ESD |
| ISO 7637-2 compliance | Meets Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupling) for 12 V/24 V systems |
| Glass passivated junction | Enhances long-term reliability and stability of breakdown voltage under thermal and humidity stress |
| Moisture sensitivity level 1 | Zero floor life limitation - can be stored indefinitely at ≤30°C/60% RH without dry-pack or baking prior to reflow |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained applications |
Applications
| Automotive Power Distribution | Industrial DC/DC Converters |
|---|---|
Use Scenario: Protecting 12 V/24 V power rails in body control modules against load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Bidirectional TVS device absorbing transient energy while maintaining stable clamping voltage across polarity reversals. Use Value: Enables compliance with ISO 7637-2 Pulse 1 (100 V/400 ms) and Pulse 2b (−100 V/50 ms) without derating or external circuitry. | Use Scenario: Safeguarding isolated flyback or forward converter secondary-side outputs from reflected surges and ESD events. IC Role / Device Role / Timing Role: Standoff-clamp protector placed across output capacitor or rectifier output. Use Value: Limits output voltage overshoot to ≤85.0 V during 400 W transients, preserving downstream regulator and load integrity. |
| LED Driver Power Inputs | Telecom Power Interfaces |
Use Scenario: Input surge protection for constant-current LED drivers in streetlight and signage applications exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary-line TVS connected between input rail and ground to shunt high-energy transients. Use Value: Withstands repeated 10/1000 µs surges up to 400 W while maintaining <1 µA leakage at 53.0 V standoff, minimizing standby losses. | Use Scenario: Protection of -48 V telecom power feeds against accidental cross-connects and lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Bidirectional clamp across power pair to suppress differential and common-mode transients simultaneously. Use Value: Symmetric 58.9–65.1 V breakdown ensures balanced clamping regardless of surge polarity, critical for negative-rail systems. |
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 | 600 W peak power, SMB package (larger footprint), VBR = 60.8–67.2 V, VC = 103 V @ 5.9 A | Higher power rating but larger board area; less suitable for space-constrained automotive modules | Select when higher surge margin is required and PCB layout allows SMB footprint |
| 1.5KE68CA | 1500 W peak power, DO-201AD axial package, VBR = 64.6–71.4 V, VC = 112 V @ 13.4 A | Through-hole mounting only; incompatible with automated SMT assembly | Choose only for prototyping or legacy through-hole designs where rework is acceptable |
Compared with SMBJ64CA and 1.5KE68CA, the P4SMA62CAH offers optimal balance of 400 W surge capability, DO-214AC SMT compatibility, AEC-Q101 qualification, and compact size-making it preferred for production automotive and industrial PCBs requiring automated assembly and strict environmental compliance.

FAQ
What does the 'CAH' suffix indicate in P4SMA62CAH?
The 'CAH' suffix denotes a bidirectional configuration with A-grade tolerance (tighter VBR spread: 58.9–65.1 V vs. standard H-grade 55.8–68.2 V) and halogen-free construction per IEC 61249-2-21. This distinguishes P4SMA62CAH from unidirectional P4SMA62AH and broader-family P4SMA62H variants. All versions share the same DO-214AC package and 400 W rating.
Is P4SMA62CAH suitable for ISO 7637-2 Pulse 1 compliance testing?
Yes, P4SMA62CAH meets ISO 7637-2 Pulse 1 (load dump) requirements when used with appropriate series impedance. Its 85.0 V clamping voltage at 5.0 A and 400 W peak power rating enable effective suppression of the 100 V/400 ms transient waveform typical in 12 V automotive systems, provided layout minimizes parasitic inductance.
Does P4SMA62CAH require derating at elevated ambient temperatures?
Yes, P4SMA62CAH must be derated above 25°C ambient per Figure 2 in the datasheet. At 85°C ambient, its peak pulse power drops to approximately 260 W (65% of 400 W), and at 125°C, it falls to ~140 W. Designers must apply this thermal derating when sizing for sustained high-temperature environments like engine compartments.
Can P4SMA62CAH replace unidirectional TVS diodes in existing designs?
P4SMA62CAH can replace unidirectional variants only if circuit topology permits bidirectional clamping-e.g., across floating rails or AC-coupled signals. It must not be substituted in series with polarized components like electrolytic capacitors or unidirectional rectifiers without verifying reverse-voltage blocking behavior and clamping symmetry in both directions.
What is the moisture sensitivity level (MSL) and floor life of P4SMA62CAH?
P4SMA62CAH has MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without dry-packaging or baking. No floor life limitation applies, eliminating pre-reflow baking steps and supporting just-in-time SMT assembly in high-volume manufacturing environments.
