Product details
Overview
P4SMA200AHM3/H from Vishay General Semiconductor is a unidirectional 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 delivers 1.1 A peak pulse current (IPPM) with 274 V clamping voltage (VC) and is AEC-Q101 qualified for automotive-grade transient protection on power rails and signal lines.
For engineers reviewing the P4SMA200AHM3/H datasheet, P4SMA200AHM3/H pinout, P4SMA200AHM3/H application, or P4SMA200AHM3/H equivalent, this device is selected for robust overvoltage protection in high-reliability DC power inputs, automotive body electronics, industrial sensor interfaces, and telecom line conditioning where low leakage (<1 µA at VWM), fast response (<1 ns), and halogen-free RoHS compliance are required.
Technical Context
The P4SMA200AHM3/H operates as a unidirectional clamping TVS diode, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response to transients. Its 200 V stand-off rating allows stable operation up to 200 V DC, while maintaining <1 µA reverse leakage at rated VWM - critical for low-power sensor supply rails.
Designed for 10/1000 µs surge waveforms per IEC 61000-4-5, it sustains 400 W peak pulse power when mounted on 5.0 mm × 5.0 mm copper pads, with thermal resistance RθJA = 120 °C/W enabling reliable operation up to +150 °C junction temperature. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC operating margin. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA test current - precise threshold where avalanche conduction initiates under transient stress. |
| VC (Clamping Voltage) | 274 V at 1.1 A IPPM - maximum voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 400 W (10/1000 µs) - energy-handling capability under standardized surge waveform; derates above 25 °C ambient. |
| ID (Reverse Leakage) | <1 µA at 200 V - ensures minimal quiescent power loss and signal integrity in high-impedance circuits. |
| TJ max | +150 °C - enables use in under-hood automotive environments and thermally constrained industrial enclosures. |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 5.28 mm length, 4.50 mm width, and 2.29 mm height; compatible with automated placement. |
Pinout & Package
Package: SMA (DO-214AC), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected circuit. | Provides low forward voltage drop (~3.5 V at 25 A) during surge conduction; must be tied to ground or return path in unidirectional configuration. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to higher-potential side (e.g., VBUS). | Defines polarity-sensitive clamping direction; reverse-biased during normal operation; avalanches into conduction when VBUS exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body control units, and ADAS sensor interfaces requiring zero-failure reliability. |

| 400 W peak pulse power (10/1000 µs) | Handles IEC 61000-4-5 Level 3 surges (1 kV/2 kV) on 12 V/24 V systems with margin; suitable for CAN, LIN, and power rail protection. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulses), improving clamping precision and system immunity. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-related delamination or popcorn failure. |

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 | Same VWM/VBR/VC ratings but in larger SMB (DO-214AA) package; 600 W PPPM rating; higher thermal mass. | Better suited for higher-energy surges or less dense PCB layouts; requires larger pad area (7.0 mm × 6.2 mm vs. 5.3 mm × 4.5 mm). | Select SMBJ200A when board space permits and surge energy exceeds 400 W; otherwise P4SMA200AHM3/H offers superior density. |
| 1.5SMC200A | Same electrical specs but in SMC (DO-214AB) package; 1500 W PPPM; higher IFSM (200 A); no AEC-Q101 qualification. | Targeted at industrial mains-input protection rather than automotive or compact DC systems; lacks automotive reliability validation. | Choose 1.5SMC200A only for non-automotive, high-surge applications where AEC-Q101 is not required and board space allows SMC footprint. |
Compared with SMBJ200A and 1.5SMC200A, the P4SMA200AHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and SMA package density - making it the preferred choice for space-constrained automotive and industrial DC power protection where regulatory compliance and reliability are non-negotiable.

FAQ
What is the clamping voltage of the P4SMA200AHM3/H under a 10/1000 µs surge?
The P4SMA200AHM3/H has a maximum clamping voltage (VC) of 274 V at 1.1 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88367 and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P4SMA200AHM3/H suitable for automotive applications?
Yes, the P4SMA200AHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive use. It meets stringent reliability requirements for under-hood and cabin electronics, including engine control units, body control modules, and ADAS sensor interfaces where transient immunity and long-term stability are essential.
What does the "HM3" suffix mean in P4SMA200AHM3/H?
The "HM3" suffix in P4SMA200AHM3/H denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction per Vishay's ordering nomenclature. It confirms compliance with automotive environmental and reliability standards, distinguishing it from commercial-grade E3/M3 variants and ensuring suitability for high-reliability automotive and industrial deployments.
What is the reverse leakage current of the P4SMA200AHM3/H at its rated standoff voltage?
The P4SMA200AHM3/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 200 V standoff voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance sensor circuits and battery-powered systems where quiescent current is tightly constrained.
Does the P4SMA200AHM3/H have a defined polarity marking, and how is it identified?
Yes, the P4SMA200AHM3/H is a unidirectional TVS diode with polarity clearly marked: a cathode band is printed on the SMA (DO-214AC) package body. During PCB layout, the banded end must be connected to the higher-potential node (e.g., VBUS), while the anode connects to ground or return - incorrect orientation prevents proper clamping function.
