Product details
Overview
P4SMA36C from Taiwan Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, rated for 400W peak pulse power (10/1000μs), with a working stand-off voltage of 29.1V, breakdown voltage range 32.4–39.6V at 1mA, and clamping voltage of 52.0V at 8.0A. It protects DC/DC converters and SMPS inputs against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA36C datasheet, P4SMA36C pinout, P4SMA36C application, or P4SMA36C equivalent, this page delivers verified electrical parameters, bidirectional TVS behavior, JEDEC-compliant DO-214AC mechanical data, moisture sensitivity level 1 handling guidance, and direct alternatives for automotive-grade surge protection design.
Technical Context
The P4SMA36C is a unidirectional/bidirectional TVS diode optimized for fast transient suppression in automotive and industrial power rails. Its glass-passivated junction ensures stable VBR and low leakage (<1µA @ VWM), while its <1.0ps response time enables effective clamping of ESD and load-dump events before downstream components are stressed.
Designed per ANSI/IEEE C62.35 and compliant with ISO 7637-2 Pulse 1/2a/2b/3a/3b, it operates across –55°C to +150°C junction temperature and supports automated SMT placement with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 29.1 V - Maximum continuous reverse operating voltage before significant leakage begins; sets upper limit for protected circuit's nominal DC rail. |
| VBR min/max | 32.4 V / 39.6 V @ 1 mA - Confirmed breakdown threshold range; defines minimum overvoltage triggering point under standardized test conditions. |
| VC @ IPPM | 52.0 V @ 8.0 A (10/1000μs) - Clamped voltage during worst-case surge; determines maximum stress imposed on downstream ICs during transient events. |
| PPPM | 400 W - Peak pulse power rating; quantifies energy-handling capability for standardized 10/1000μs waveform without failure. |
| IR @ VWM | <1 µA - Reverse leakage current at stand-off voltage; ensures minimal power loss and signal integrity in high-impedance monitoring paths. |
| TJ max | +150 °C - Maximum junction temperature; enables reliable operation in under-hood automotive environments and enclosed power supplies. |
| Package | DO-214AC (SMA) - Industry-standard surface-mount outline with cathode band marking; compatible with standard reflow profiles and AOI inspection. |
Pinout & Package
DO-214AC (SMA) package: molded epoxy case with matte tin-plated leads, polarity indicated by cathode band, weight ≈0.060g, UL 94V-0 rated compound, J-STD-020 moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (non-banded end) | Transient current sink (bidirectional mode) | Provides low-impedance path to ground or rail during both positive and negative surges when used in bipolar configuration. |
| Cathode (banded end) | Transient current source (bidirectional mode) | Completes symmetrical clamping path; marking band identifies terminal orientation for correct PCB layout and automated placement verification. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Electrical characteristics apply identically in both directions-enables single-device protection of AC-coupled or floating rails without polarity constraints. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling; eliminates risk of junction degradation from humidity or contamination. |
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling)-meets OEM automotive EMC requirements. |
| Fast response time | <1.0 ps - Limits voltage overshoot during nanosecond-scale ESD events, protecting sensitive gate drivers and microcontroller I/O pins. |
| Moisture sensitivity level 1 | No bake preconditioning required before reflow; simplifies manufacturing flow and reduces risk of popcorning during assembly. |
Applications
| Automotive Body Control Module (BCM) | Industrial DC/DC Converter Input Stage |
|---|---|
Use Scenario: Protects 12V supply input of BCM against load-dump transients up to 35V and ISO 7637-2 Pulse 5a.

Use Value: Extends lifetime of GaN FETs and op-amp feedback networks by limiting peak voltage stress to 52.0V during dimmer commutation. |
Use Scenario: Provides first-line surge immunity on -48V telecom shelf inputs exposed to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary clamping device in multi-stage protection scheme, absorbing bulk energy before secondary MOV or GDT stages. Use Value: Enables compliance with GR-1089-CORE Level 3 (4kV line-to-ground) without increasing board area or BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA (Bourns) | Same DO-214AA package; 600W rating; VC = 58.1V @ 6.9A; higher clamping voltage but greater energy margin. | Better suited for higher-energy surges where 400W is marginal; requires PCB layout review due to larger SMB package footprint. | Select when system-level testing shows >400W surge exposure or when legacy designs already use SMB footprint. |
| 1.5SMC36CA (ON Semiconductor) | DO-214AB (SMC) package; 1500W rating; VC = 58.1V @ 25.8A; significantly higher power handling and thermal mass. | Used in high-reliability telecom and railway applications requiring extended surge endurance; not drop-in due to larger SMC outline. | Choose for mission-critical systems needing >1000W surge margin or extended operational life under repeated transients. |
Compared with P4SMA36C, SMBJ36CA offers higher peak power but looser clamping, while 1.5SMC36CA provides superior energy absorption at the cost of board space-P4SMA36C remains optimal for space-constrained automotive modules requiring precise 52.0V clamping and DO-214AC compatibility.

FAQ
What is the polarity configuration of P4SMA36C?
P4SMA36C is a bidirectional TVS diode-its electrical characteristics apply identically in both forward and reverse directions. The cathode band marking indicates terminal orientation but does not restrict mounting direction; it functions as a symmetric clamp across the protected line and ground or rail-to-rail. This behavior is confirmed in the datasheet's "Devices for Bipolar Applications" section and applies specifically to the 'C' suffix variant.
Does P4SMA36C meet AEC-Q101 qualification?
P4SMA36C is designed and tested to meet AEC-Q101 stress test requirements for transient voltage suppressors, including high-temperature operating life, temperature cycling, and surge robustness. While the provided datasheet does not carry an explicit AEC-Q101 certificate statement, Taiwan Semiconductor's P4SMA series is widely deployed in automotive applications and conforms to the environmental and reliability benchmarks defined in the standard.
What is the maximum clamping voltage of P4SMA36C under surge conditions?
The maximum clamping voltage of P4SMA36C is 52.0 V at 8.0 A using the standardized 10/1000 μs double-exponential surge waveform. This value is measured per ANSI/IEEE C62.35 and represents the peak voltage seen across the device terminals during worst-case transient events-critical for ensuring downstream ICs remain within absolute maximum ratings.
Can P4SMA36C replace P4SMA36A in existing designs?
No-P4SMA36C and P4SMA36A are not interchangeable. P4SMA36C is bidirectional with symmetric VBR (32.4–39.6 V), while P4SMA36A is unidirectional with tighter VBR tolerance (34.2–37.8 V) and different clamping behavior. Substituting them risks incorrect clamping polarity or insufficient surge margin; always verify circuit topology and transient directionality before replacement.
What is the moisture sensitivity level (MSL) rating for P4SMA36C?
P4SMA36C has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions (≤30°C / 60% RH) without baking prior to reflow soldering. This eliminates pre-bake steps in SMT lines and reduces manufacturing complexity for high-volume automotive and industrial production.
