Product details
Overview
P4SMA200CAHM3/I 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), 210 V minimum breakdown voltage (VBR), and 400 W peak pulse power (10/1000 µs). It clamps transients to 274 V at 1.1 A peak pulse current and is AEC-Q101 qualified for automotive-grade reliability in power line and signal line protection.
For engineers reviewing the P4SMA200CAHM3/I datasheet, P4SMA200CAHM3/I pinout, P4SMA200CAHM3/I application, or P4SMA200CAHM3/I equivalent, this device serves as a robust, low-profile, halogen-free TVS solution for bidirectional surge suppression in automotive sensor interfaces, industrial control I/O, and telecom power rails where stable clamping, fast response (<1 ns), and MSL Level 1 reflow compatibility are required.
Technical Context
The P4SMA200CAHM3/I operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1 µA at 171 V).
Designed for transient immunity per IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive load dump), it delivers 274 V clamping voltage at 1.1 A IPPM under 10/1000 µs waveform, with thermal resistance RθJA = 120 °C/W and maximum junction temperature of +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 210 V min / 231 V max at 1 mA - Avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 274 V at IPPM = 1.1 A (10/1000 µs) - Peak voltage seen by protected circuit during surge; critical for IC survival. |
| PPPM (Peak Pulse Power) | 400 W - Sustained transient energy handling capability under standard 10/1000 µs waveform; derates above 25 °C. |
| ID (Reverse Leakage) | <1 µA at 171 V - Minimal standby current; avoids power loss or false triggering in high-impedance circuits. |

| Telecom DC Power Rail Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Guarding 48 V PoE-powered Ethernet switch ports and base station RF module power feeds against induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: Primary-level TVS on DC input rail upstream of DC/DC converter, sized to absorb bulk energy before secondary-stage protection engages. Use Value: 200 V VWM aligns with 48 V nominal + 150 % safety margin; 274 V VC ensures downstream converters remain within absolute maximum ratings. |
Use Scenario: Shielding microcontroller GPIOs and H-bridge gate drivers in smart washing machines and HVAC blower systems from motor commutation spikes. IC Role / Device Role / Timing Role: Localized TVS at motor driver IC supply pins and feedback signal lines to suppress fast-rising inductive kickback (di/dt > 10 A/ns). Use Value: Sub-nanosecond response and low incremental surge resistance minimize voltage overshoot, reducing risk of MOSFET avalanche failure or MCU reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same VWM/VBR/VC specs but in larger SMB (DO-214AA) package; 600 W PPPM rating | Higher power handling suits higher-energy surges but requires 30 % more board area | Select when system-level surge testing exceeds IEC 61000-4-5 Level 3 (1 kV/2 kV); not drop-in due to footprint mismatch |
| 1.5KE200CA | Through-hole DO-201 package; same 200 V VWM, but 1500 W PPPM and higher VC (275 V) | Used in legacy industrial power supplies where manual assembly or high-reliability through-hole mounting is mandated | Choose only for through-hole designs requiring higher single-pulse energy absorption; incompatible with SMT-only production |
Compared with SMBJ200CA and 1.5KE200CA, the P4SMA200CAHM3/I offers optimal balance of automotive qualification, compact SMA footprint, and verified 400 W surge capability-making it preferred for space-constrained, high-volume SMT automotive and industrial modules where AEC-Q101 compliance and reflow compatibility are mandatory.

FAQ
What is the clamping voltage of the P4SMA200CAHM3/I at its rated peak pulse current?
The P4SMA200CAHM3/I clamps to a maximum of 274 V at its specified peak pulse current (IPPM) of 1.1 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and reflects worst-case voltage seen by protected circuitry during surge events, directly supporting design margin calculations for downstream ICs.
Is the P4SMA200CAHM3/I suitable for automotive applications?
Yes, the P4SMA200CAHM3/I is AEC-Q101 qualified (denoted by the HM3 suffix), meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life required for automotive electronic control units. It is explicitly rated for use in engine management, body electronics, and ADAS sensor interfaces per Vishay's qualification documentation.
Does the P4SMA200CAHM3/I have polarity markings on the package?
No, the P4SMA200CAHM3/I is a bidirectional TVS diode and carries no polarity marking on the SMA (DO-214AC) package. Its symmetrical construction means either terminal may be connected to line or ground-eliminating orientation errors during automated placement and simplifying PCB layout for differential or floating signal paths.
What is the maximum junction temperature rating for the P4SMA200CAHM3/I?
The P4SMA200CAHM3/I has a maximum junction temperature (TJ) rating of +150 °C, consistent across its full operating range of -65 °C to +150 °C. This rating supports reliable operation in under-hood automotive environments and enclosed industrial enclosures, provided thermal design accounts for its RθJA of 120 °C/W and power dissipation limits.
How does the HM3 suffix differ from the M3 or E3 suffix in the P4SMA200CAHM3/I part number?
The HM3 suffix in P4SMA200CAHM3/I indicates halogen-free, RoHS-compliant construction *and* AEC-Q101 qualification. In contrast, M3 denotes halogen-free/RoHS without automotive qualification, and E3 denotes RoHS-compliant commercial grade only. The HM3 variant is specifically validated for automotive use cases where both material compliance and reliability certification are mandatory.
