Product details
Overview
P4SMA200CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), and SMA (DO-214AC) package - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the P4SMA200CAHM3/H datasheet, P4SMA200CAHM3/H pinout, P4SMA200CAHM3/H application, or P4SMA200CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 274 V maximum clamping voltage at rated IPPM, low incremental surge resistance, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
The P4SMA200CAHM3/H operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns) to ESD and lightning-induced surges.
Rated for 150 °C maximum junction temperature and MSL Level 1 moisture sensitivity, it delivers 274 V clamping voltage at 1.1 A peak pulse current (IPPM), with 0.01 % duty cycle derating above 25 °C ambient - validated under JEDEC J-STD-020 reflow conditions up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 220 V min - Avalanche conduction initiates reliably at this voltage under 1 mA test current |
| VC (Clamping Voltage) | 274 V max at IPPM = 1.1 A - Limits downstream circuit voltage during 10/1000 µs surge |
| PPPM (Peak Pulse Power) | 400 W - Sustains single 10/1000 µs transients on 5.0 mm × 5.0 mm copper pads |
| Package | SMA (DO-214AC) - Surface-mount footprint compatible with automated placement; 2.54 mm lead pitch |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability per HM3 suffix designation |
| RoHS & Halogen-Free | Yes - Complies with JEDEC JESD201 Class 2 whisker resistance and UL 94 V-0 flammability |

Applications
| Automotive Sensor Protection | Industrial Digital I/O Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed between signal line and chassis ground to clamp transients before reaching MCU input pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | 600 W PPPM, SMB package (DO-214AA), higher thermal mass but larger footprint | Better suited for higher-energy surges where board space allows larger package | Select when >400 W pulse handling is required and layout accommodates 3.56 mm × 4.60 mm outline |
| 1.5KE200CA | 1500 W PPPM, axial DO-201AD package, higher capacitance (~100 pF), through-hole mounting | Used in legacy power supply designs with through-hole assembly and higher surge immunity needs | Choose only for retrofit or high-reliability mains-input protection where SMT is not feasible |
Compared with SMBJ200CA and 1.5KE200CA, the P4SMA200CAHM3/H offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and precise 200 V standoff for modern automotive and industrial SMT systems - without sacrificing clamping performance or manufacturability.

FAQ
What is the clamping voltage of P4SMA200CAHM3/H at its rated peak pulse current?
The P4SMA200CAHM3/H has a maximum clamping voltage (VC) of 274 V at its rated peak pulse current (IPPM) of 1.1 A under the standard 10/1000 µs waveform. This value is measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per Vishay's test condition - critical for accurate system-level surge margin calculation in designs using the P4SMA200CAHM3/H.
Is P4SMA200CAHM3/H suitable for automotive applications?
Yes, the P4SMA200CAHM3/H is AEC-Q101 qualified (denoted by the HM3 suffix) and rated for operation from −65 °C to +150 °C junction temperature. It meets automotive requirements for surge immunity, thermal cycling, and long-term reliability - making it appropriate for use in engine control units, body electronics, and ADAS sensor interfaces where the P4SMA200CAHM3/H provides certified transient protection.
How does the CA suffix in P4SMA200CAHM3/H affect its functionality?
The "CA" suffix in P4SMA200CAHM3/H indicates a bidirectional configuration: the device clamps voltage transients equally in both polarities, with no cathode marking and symmetrical VBR and VC characteristics. This enables single-device protection of AC signals, floating buses, or differential lines - unlike unidirectional "A" variants which require correct polarity orientation during PCB layout for the P4SMA200CAHM3/H.
What is the thermal resistance of P4SMA200CAHM3/H, and how does it impact power dissipation?
The P4SMA200CAHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. At 25 °C ambient, its steady-state power dissipation (PD) is rated at 3.3 W - meaning sustained power must be limited well below this value in real-world layouts, especially given its 150 °C max junction temperature. Derating curves in the datasheet must be applied when using the P4SMA200CAHM3/H in elevated ambient environments.
Does P4SMA200CAHM3/H meet RoHS and halogen-free standards?
Yes, the HM3 suffix confirms the P4SMA200CAHM3/H is both RoHS-compliant and halogen-free per JEDEC JESD201 Class 2 whisker resistance requirements. The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin plated - satisfying environmental compliance mandates for automotive, industrial, and consumer electronics where the P4SMA200CAHM3/H is deployed.
