Product details
Overview
P6SMB200CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 220 V breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to 274 V at 2.2 A peak pulse current and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive-grade surge protection on power rails and signal lines.
For engineers reviewing the P6SMB200CAHM3/I datasheet, P6SMB200CAHM3/I pinout, P6SMB200CAHM3/I application, or P6SMB200CAHM3/I equivalent, this device serves as a robust, low-profile, automated-placement-ready TVS for high-reliability transient suppression where bidirectional clamping, MSL Level 1 solderability, and stable clamping voltage under repetitive surges are required.
Technical Context
The P6SMB200CAHM3/I operates as a bidirectional avalanche diode, symmetrically clamping voltage transients above ±220 V (VBR min) with a maximum clamping voltage of 274 V at 2.2 A IPPM. Its glass-passivated junction ensures stable leakage (<1.0 μA at 171 V) and fast response time (<1.0 ns), enabling protection of sensitive downstream circuitry against ESD, lightning-induced surges, and inductive switching spikes.
Designed for surface-mount assembly on 0.2" × 0.2" copper pads, it delivers 600 W peak pulse power with 0.01% duty cycle, derates linearly above 25 °C (RθJA = 100 °C/W), and maintains operation across -65 °C to +150 °C junction temperature range - meeting automotive reliability requirements per AEC-Q101 when ordered with HM3 suffix.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM/VBR/VC ratings but lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy surges; less suitable for automotive load-dump or telecom line protection requiring 600 W. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin at elevated ambient. |
| 1.5KE200CA | Through-hole TO-218 package, same 200 V VWM, but higher VC (275 V) and larger form factor; not surface-mountable. | Requires manual or wave-solder assembly; incompatible with automated SMT lines and dense PCB layouts. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMAJ200CA and 1.5KE200CA, the P6SMB200CAHM3/I uniquely combines 600 W surge capability, SMB surface-mount compatibility, AEC-Q101 qualification, and halogen-free construction - making it the preferred choice for production automotive and industrial SMT designs demanding high-reliability bidirectional clamping.

FAQ
What does the "CA" suffix indicate in P6SMB200CAHM3/I?
The "CA" suffix in P6SMB200CAHM3/I denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities - essential for protecting AC-coupled or floating differential signal lines such as RS-485, CAN, or USB without regard to polarity orientation. This differs from unidirectional "A" variants that require correct cathode alignment.
Is P6SMB200CAHM3/I suitable for automotive applications?
Yes, P6SMB200CAHM3/I is AEC-Q101 qualified (indicated by the HM3 suffix), tested for temperature cycling, high-temperature reverse bias, and surge endurance per automotive reliability standards. It is approved for use in engine control modules, body electronics, infotainment systems, and ADAS sensor interfaces where robust transient immunity is required.
What is the maximum clamping voltage of P6SMB200CAHM3/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB200CAHM3/I is 274 V at a peak pulse current (IPPM) of 2.2 A, measured using the standardized 10/1000 μs waveform. This value represents the highest voltage imposed on protected circuitry during a defined surge event and is critical for ensuring downstream ICs remain within their absolute maximum ratings.
How does the HM3 suffix differ from M3 or E3 in P6SMB200CAHM3/I?
The HM3 suffix in P6SMB200CAHM3/I indicates halogen-free, RoHS-compliant construction *and* AEC-Q101 qualification - distinguishing it from M3 (halogen-free, commercial grade only) and E3 (RoHS-compliant, commercial grade). HM3 ensures compliance with both environmental regulations and automotive reliability testing protocols.
What PCB layout guidance applies to P6SMB200CAHM3/I for optimal surge performance?
For optimal surge performance, P6SMB200CAHM3/I must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W peak pulse power. Short, low-inductance traces to ground and minimized loop area between the TVS and protected node are essential to preserve its sub-1 ns response and prevent voltage overshoot during fast transients.
