Product details
Overview
P4SMA200CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 400 W peak pulse power (10/1000 µs waveform). It provides clamping protection for signal lines and power rails in automotive sensor interfaces, industrial I/O modules, and telecom line cards.
For engineers reviewing the P4SMA200CAHM3_A/H datasheet, P4SMA200CAHM3_A/H pinout, P4SMA200CAHM3_A/H application, or P4SMA200CAHM3_A/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers verified bidirectional surge suppression with 274 V maximum clamping voltage at 1.1 A peak pulse current - critical for ESD and lightning transient hardening in safety-critical embedded systems.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 171 V), but switches to low-impedance conduction within <1 ns when transients exceed its breakdown threshold. Its bidirectional symmetry ensures identical clamping behavior for positive and negative surges.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it delivers 400 W pulse handling up to 150 °C junction temperature, with thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), enabling reliable operation without heatsinking in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for 24–48 V DC systems. |
| VBR (Min) | 220 V at 1 mA test current - Confirmed breakdown onset; ensures predictable turn-on above nominal rail voltage. |
| VC (Max @ IPPM) | 274 V at 1.1 A - Clamping voltage during 10/1000 µs surge; limits downstream voltage stress to ≤37 % above VWM. |
| PPPM | 400 W - Peak pulse power rating per JEDEC standard; supports repetitive surge events at 0.01 % duty cycle. |
| IPPM | 1.1 A - Peak pulse current corresponding to VC; determines minimum series impedance required for effective energy diversion. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive and industrial environments. |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN FD and LIN bus transceivers from load dump and ISO 7637-2 pulses in vehicle cabin modules. IC Role / Device Role / Timing Role: Shunt TVS placed directly at connector entry point to clamp transients before reaching PHY IC. Use Value: Maintains signal integrity below 274 V clamping level while surviving 400 W pulses - prevents latch-up and permanent damage to transceiver silicon. |
Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers against field-wiring induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on isolated input stage, coordinated with optocoupler and series resistor. Use Value: Enables robust immunity to IEC 61000-4-4 EFT bursts (±2 kV) and 61000-4-5 surges (±1 kV) without derating or parallel devices. |
| Telecom Line Interface | Consumer Power Adapter Output |
Use Scenario: Protecting Ethernet PHYs and PoE injectors from lightning-induced common-mode surges on RJ45 ports. IC Role / Device Role / Timing Role: Bidirectional TVS across differential pairs (e.g., TX+/TX−) to suppress mode conversion transients. Use Value: Symmetric clamping preserves differential signaling integrity while limiting common-mode voltage excursion to <274 V. |
Use Scenario: Secondary-side overvoltage suppression on 12 V/19 V DC outputs of laptop adapters exposed to hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Final-stage clamp after DC-DC regulator, absorbing fast-rising ESD (IEC 61000-4-2 ±8 kV contact). Use Value: Sub-1 ns response time and 274 V clamping prevent downstream USB-C PD controller reset or MOSFET gate oxide failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same VWM/VBR, but SMB package (DO-214AA); 600 W PPPM, higher IPPM (3.3 A), larger footprint. | Higher power handling suits 48 V industrial buses; requires PCB layout change due to 2.54 mm lead pitch vs. SMA's 2.29 mm. | Select when surge energy exceeds 400 W or board space allows larger package. |
| 1.5KE200CA | Through-hole TO-204AA (DO-41); same VWM/VBR, 1500 W PPPM, 12.5 A IPPM, higher thermal mass. | Used in legacy designs or high-reliability power supplies where manual assembly or wave soldering is preferred. | Choose only for through-hole production or when >600 W pulse capability is mandatory. |

FAQ
What is the clamping voltage of P4SMA200CAHM3_A/H at its rated peak pulse current?
The P4SMA200CAHM3_A/H has a maximum clamping voltage (VC) of 274 V at 1.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The P4SMA200CAHM3_A/H maintains this clamping performance across its full operating temperature range of -65 °C to +150 °C.
Is P4SMA200CAHM3_A/H suitable for automotive applications?
Yes, P4SMA200CAHM3_A/H is AEC-Q101 qualified and specifically designed for automotive use. Its halogen-free, RoHS-compliant construction, MSL Level 1 rating, and validated performance across -65 °C to +150 °C junction temperature meet stringent automotive reliability requirements. The P4SMA200CAHM3_A/H is commonly deployed in engine control units, ADAS camera modules, and infotainment system power rails.
How does the bidirectional design of P4SMA200CAHM3_A/H affect PCB layout?
The bidirectional design of P4SMA200CAHM3_A/H eliminates polarity marking and orientation constraints - either terminal may connect to line or return, simplifying layout and reducing assembly errors. No cathode band identification is present, and the SMA (DO-214AC) footprint requires only two 0.2" × 0.2" copper pads per terminal. This symmetry makes P4SMA200CAHM3_A/H ideal for protecting differential signals like CAN, RS-485, or Ethernet pairs.
What is the maximum steady-state power dissipation of P4SMA200CAHM3_A/H?
The P4SMA200CAHM3_A/H has a maximum steady-state power dissipation (PD) of 3.3 W at 50 °C ambient temperature on an infinite heatsink. In typical PCB mounting (0.2" × 0.2" copper pads), derating applies per Figure 2 in the datasheet; at 70 °C ambient, usable power drops to approximately 2.2 W. This rating governs continuous leakage current handling, not transient surge capability.
Does P4SMA200CAHM3_A/H meet UL recognition requirements?
Yes, P4SMA200CAHM3_A/H carries Underwriters Laboratory Recognition under file E136766 for both unidirectional and bidirectional configurations, compliant with UL 497B for signal circuit protectors. This certification confirms suitability for use in end equipment requiring UL listing, including industrial control panels and telecom infrastructure hardware where surge protection must meet safety agency requirements.
