Product details
Overview
P4SMA200C 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), 162V working stand-off voltage (VWM), and 287V maximum clamping voltage (VC@IPPM). It protects DC/DC converters and automotive power electronics against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA200C datasheet, P4SMA200C pinout, P4SMA200C application, or P4SMA200C equivalent, key selection criteria include bidirectional clamping capability, low leakage (<1μA at VWM), ±10% VBR tolerance (180–220V), 150°C junction rating, and compliance with J-STD-020 Level 1 moisture sensitivity.
Technical Context
The P4SMA200C implements a glass-passivated silicon junction optimized for fast transient suppression, with sub-1ps response time and bidirectional symmetry enabling use in AC-coupled or floating bus protection without polarity constraints. Its breakdown voltage (VBR) is specified at 1.0mA test current with ±10% min/max spread (180–220V), and it maintains <1μA reverse leakage at 162V VWM.
Designed for high-reliability industrial and automotive environments, the device meets ISO 7637-2 immunity requirements for load dump and inductive switching transients, operates across –55°C to +150°C, and features 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 |
|---|---|
| VWM | 162 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR @ IT=1mA | 180–220 V - Breakdown voltage range ensuring reliable turn-on during overvoltage events |
| VC @ IPPM | 287 V - Clamped voltage under 400W 10/1000μs surge, limiting downstream stress |
| IPPM | 1.4 A - Peak impulse current capacity at rated clamping voltage |
| PPPM | 400 W - Peak pulse power handling per single non-repetitive 10/1000μs waveform |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood or enclosed power systems |
| IR @ VWM | <1 μA - Ultra-low leakage preserves efficiency in high-impedance sensing or standby circuits |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking; 0.060g mass; UL 94V-0 molding compound; matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Transient current entry point (bidirectional) | Accepts surge current in either polarity; no fixed anode/cathode function due to symmetrical construction |
| Cathode (banded end) | Transient current exit point (bidirectional) | Functions as return path during positive or negative transients; band denotes terminal orientation only |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR and low leakage over temperature and lifetime, critical for automotive-grade reliability |
| ISO 7637-2 compliance | Validated immunity to Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnection), and Pulse 3a/3b (line spikes), eliminating need for external validation |
| J-STD-020 Level 1 moisture rating | Enables standard SMT reflow without baking, reducing manufacturing cost and process risk |
| Bidirectional configuration (C suffix) | Supports AC signal lines or ungrounded DC buses without polarity concerns-no separate unidirectional part selection required |
Applications
| Automotive Power Distribution | Industrial DC/DC Converters |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA (Bourns) | Same DO-214AA package; 200V VBR min/max tighter (190–210V); 30% higher IPPM (1.8A) | Higher surge margin suits repetitive industrial surge environments; slightly larger thermal pad required | Select SMBJ200CA when >1.5A IPPM headroom is needed or DO-214AA layout already exists |
| 1.5SMC200CA (ON Semiconductor) | DO-214AB (SMC) package; 200V VBR (190–210V); same 400W rating but 2.2A IPPM | Larger SMC footprint increases board area but improves thermal dissipation for frequent surges | Choose 1.5SMC200CA where sustained surge duty cycle exceeds 10x/hour and thermal management is critical |
Compared with SMBJ200CA and 1.5SMC200CA, the P4SMA200C offers identical electrical performance in a smaller DO-214AC footprint-ideal for space-constrained automotive modules where layout reuse and JEDEC-standard SMA placement are prioritized over marginal IPPM gain.

FAQ
What is the polarity configuration of the P4SMA200C?
The P4SMA200C is a bidirectional TVS diode, indicated by the "C" suffix. It has symmetrical breakdown characteristics in both directions, with no functional anode or cathode-only a physical cathode band for orientation reference. This enables use on AC lines or floating DC buses without polarity-sensitive placement, unlike unidirectional variants (e.g., P4SMA200A).
Does the P4SMA200C meet automotive transient immunity standards?
Yes, the P4SMA200C meets ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b, making it suitable for 12V/24V automotive electronic control units. Its 400W peak pulse rating, 287V clamping voltage, and –55°C to +150°C operating range align with AEC-Q101 stress test conditions for transient suppression devices used in engine compartments and chassis modules.
What is the maximum clamping voltage of the P4SMA200C under surge conditions?
The P4SMA200C has a maximum clamping voltage (VC) of 287V at its rated peak pulse current (IPPM = 1.4A) using the standardized 10/1000μs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream components like MOSFETs and controllers remain within safe voltage limits during real-world transients.
Can the P4SMA200C be used in place of unidirectional TVS diodes?
No-the P4SMA200C is strictly bidirectional and not interchangeable with unidirectional types (e.g., P4SMA200A). Substituting it into a circuit designed for unidirectional clamping may cause unintended conduction during normal forward bias, leading to excessive leakage or thermal runaway. Always verify polarity requirements before replacement.
What is the moisture sensitivity level (MSL) of the P4SMA200C?
The P4SMA200C has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and subjected to standard SMT reflow profiles-including Pb-free peak temperatures up to 260°C-without preconditioning or baking. This simplifies manufacturing and reduces assembly risk in high-volume production.
