Product details
Overview
P4SMA200CH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It delivers 400W peak pulse power handling, 200V breakdown voltage (min 180V, max 220V), clamps to ≤287V at 1.4A peak impulse current, and operates across –55°C to +150°C junction temperature range - deployed in automotive on-board DC/DC converters and industrial SMPS input stages.
For engineers reviewing the P4SMA200CH datasheet, P4SMA200CH pinout, P4SMA200CH application, or P4SMA200CH equivalent, key selection criteria include its DO-214AC (SMA) package compatibility, AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, <1μA reverse leakage at 162V working stand-off, and fast sub-1ps response time under transient stress.
Technical Context
The P4SMA200CH implements a single-die, unidirectional silicon avalanche junction structure with glass passivation for stable breakdown characteristics and low leakage. Its clamping behavior follows the 10/1000μs standard waveform per ANSI/IEEE C62.35, delivering predictable voltage limiting during ESD and load-dump events.
Designed for automated SMT placement, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1 - enabling reflow without dry-pack requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 180 V / 220 V - ensures reliable avalanche conduction onset within defined tolerance at 1.0 mA test current |
| VWM | 162 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC@IPPM | ≤287 V at 1.4 A - clamping voltage under 400W 10/1000μs surge defines protected circuit voltage ceiling |
| IPPM | 1.4 A - peak impulse current capability determines surge energy absorption (400W) |
| IR@VWM | <1 μA - ultra-low leakage preserves efficiency in high-impedance bias networks |
| TJ range | –55°C to +150°C - supports under-hood automotive and industrial ambient environments |
| Response time | <1.0 ps - enables effective suppression of nanosecond-scale ESD transients |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-ended unidirectional configuration with cathode band marking. Dimensions comply with JEDEC DO-214AC outline; weight ≈ 0.060 g.

|---|---|
Use Scenario: Protects 24V-to-5V buck converter input against load-dump surges up to 120V and ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed at primary-side input to clamp transients before they reach controller IC and MOSFET gate drivers. Use Value: Limits voltage excursion to ≤287V during 400W surge, preventing overvoltage failure of downstream 30V-rated input capacitors and controllers. | Use Scenario: Shields AC-DC front-end rectifier output and PFC stage from lightning-induced surges and switching noise. IC Role / Device Role / Timing Role: Standoff-clamp protector on bulk capacitor rail, absorbing repetitive 10/1000μs transients without degradation. Use Value: Maintains <1μA leakage at 162V working voltage, minimizing standby power loss while sustaining 150°C operation in enclosed enclosures. |
| LED Driver Input Stage | Telecom DC Power Interface |
Use Scenario: Safeguards constant-current LED driver ICs from inductive kickback when driving high-power arrays in streetlight systems. IC Role / Device Role / Timing Role: Primary-line TVS on 48V input bus, positioned upstream of input filter and controller. Use Value: Sub-1ps response captures fast-edge transients from relay switching, clamping before controller brownout or latch-up occurs. | Use Scenario: Secures -48V telecom power feed against accidental polarity reversal and induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Unidirectional suppressor referenced to system ground, protecting hot-swap controllers and PMBus monitoring ICs. Use Value: 162V VWM allows full margin below -48V nominal with negative transients, while 287V VC stays within safe operating area of -60V-rated components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | DO-214AA (SMB) package; 200V VBR min/max = 180–220V; same 400W rating but higher IPPM (1.5A) | Larger footprint (SMB vs SMA); slightly higher clamping (290V) and thermal mass | Select SMBJ200A only if board layout accommodates larger DO-214AA and requires marginally higher surge current headroom |
| 1.5SMC200A | DO-214AB (SMC) package; identical VBR/VC specs; 1500W rating (not 400W) | Substantially larger package (SMC); intended for higher-energy threats, not direct replacement | Choose 1.5SMC200A only for applications requiring >1kW surge handling - not a drop-in substitute for P4SMA200CH's space-constrained SMA layout |
Compared with SMBJ200A and 1.5SMC200A, the P4SMA200CH offers optimal balance of compact DO-214AC footprint, AEC-Q101 qualification, and precise 400W surge rating - making it preferred for automotive and space-limited industrial DC/DC modules where PCB real estate and automotive qualification are decisive.

FAQ
Is P4SMA200CH unidirectional or bidirectional?
The P4SMA200CH is a unidirectional TVS diode, indicated by the "H" suffix (as opposed to "CH" for bidirectional variants). Its cathode band marks the terminal connected to the protected line, with anode tied to reference ground. This configuration provides asymmetric clamping optimized for DC rail protection where polarity is fixed - unlike bidirectional types that protect AC or dual-rail signals.
What does the "CH" suffix mean in P4SMA200CH?
The "CH" suffix in P4SMA200CH denotes a bidirectional variant - however, per TSC documentation, the correct part number for the bidirectional version is P4SMA200AH (with "AH" suffix). The "CH" designation appears in family headers as a generic placeholder; the actual orderable bidirectional part is P4SMA200AH. P4SMA200CH is not a valid orderable part - P4SMA200AH is the verified bidirectional counterpart to P4SMA200H.
Does P4SMA200CH meet AEC-Q101 requirements?
Yes, P4SMA200CH is explicitly AEC-Q101 qualified per the provided datasheet. This includes stress testing for temperature cycling, highly accelerated life testing (HALT), and ESD robustness - confirming suitability for automotive powertrain, body electronics, and ADAS subsystems where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of P4SMA200CH at rated surge current?
The maximum clamping voltage (VC) of P4SMA200CH is 287 V at 1.4 A peak pulse current (IPPM) under the standardized 10/1000μs waveform. This value defines the upper voltage limit imposed on the protected circuit during a 400W transient event - critical for ensuring downstream components remain within their absolute maximum ratings.
Can P4SMA200CH be used in place of P4SMA200AH?
No - P4SMA200CH is not a valid replacement for P4SMA200AH. P4SMA200AH is the bidirectional variant (symmetrical clamping), while P4SMA200H is the unidirectional version. There is no official "CH"-suffixed unidirectional part in this family. Using P4SMA200H instead of P4SMA200AH would fail in AC or polarity-agnostic applications; always verify suffix against TSC's ordering table: "H" = unidirectional, "AH" = bidirectional.
