Product details
Overview
P4SMA200CAHM3_A/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), 220 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 electronics protection.
For engineers reviewing the P4SMA200CAHM3_A/I datasheet, P4SMA200CAHM3_A/I pinout, P4SMA200CAHM3_A/I application, or P4SMA200CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, and suitability for inductive load switching surge suppression in safety-critical automotive subsystems.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It exhibits low incremental surge resistance and fast response time-critical for suppressing ESD and lightning-induced surges before sensitive circuitry sustains damage.
The P4SMA200CAHM3_A/I uses a glass-passivated silicon junction and is rated for continuous power dissipation of 3.3 W at 50 °C on an infinite heatsink, with maximum junction temperature of 150 °C and thermal resistance of 120 °C/W (junction-to-ambient) under standard PCB pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR (Breakdown Voltage) | 220 V min - Voltage at which device enters avalanche conduction under 1 mA test current |
| VC (Clamping Voltage) | 274 V at IPPM = 1.1 A - Peak voltage seen by protected circuit during 10/1000 µs surge |
| PPPM (Peak Pulse Power) | 400 W - Surge energy handling capacity per single 10/1000 µs waveform |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Minimal leakage current ensuring low standby power loss |
| TJ max | 150 °C - Maximum allowable junction temperature for reliable long-term operation |
| Package | SMA (DO-214AC) - Surface-mount outline with 5.0 mm × 5.0 mm copper pad thermal requirement |

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 | Same VWM/VBR/VC ratings but SMB (DO-214AA) package - 2.5 mm wider body, higher RθJA (150 °C/W) | Less suitable for ultra-dense automotive PCBs where SMA footprint saves >18 % board area | Select P4SMA200CAHM3_A/I when space-constrained layouts or lower thermal resistance are critical |
| 1.5KE200CA | Through-hole TO-218 package; 1500 W PPPM but larger size, no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive qualification requirements | Choose P4SMA200CAHM3_A/I for SMT scalability, AEC-Q101 compliance, and consistent reflow yield |

FAQ
What is the clamping voltage of the P4SMA200CAHM3_A/I under a 10/1000 µs surge?
The P4SMA200CAHM3_A/I clamps to a maximum of 274 V when subjected to its rated peak pulse current of 1.1 A under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the P4SMA200CAHM3_A/I suitable for automotive applications?
Yes, the P4SMA200CAHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with automotive-grade reliability validation. It is explicitly intended for use in automotive subsystems such as body control modules, ADAS sensors, and powertrain electronics.
What does the "CA" suffix mean in P4SMA200CAHM3_A/I?
The "CA" suffix in P4SMA200CAHM3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VWM, VBR, and VC characteristics in forward and reverse directions, unlike unidirectional "A" variants.
Does the P4SMA200CAHM3_A/I require special handling during PCB assembly?
No special handling is required: the P4SMA200CAHM3_A/I is rated MSL Level 1 per J-STD-020, permitting unlimited exposure to ambient conditions before reflow. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, supporting standard lead-free reflow profiles without pre-baking.
How does the thermal performance of P4SMA200CAHM3_A/I compare to through-hole alternatives?
The P4SMA200CAHM3_A/I has a typical RθJA of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads - significantly better than legacy through-hole TVS devices like 1.5KE200CA (RθJA ≈ 200 °C/W). This enables higher sustained power handling in compact SMT layouts without additional heatsinking.
