Product details
Overview
P4SMA200CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMA (DO-214AC) package, designed for clamping voltage transients on signal or power lines. It features a 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), 274 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P4SMA200CAHE3/61 datasheet, P4SMA200CAHE3/61 pinout, P4SMA200CAHE3/61 application, or P4SMA200CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 274 A surge handling at 200 V, low thermal resistance (RθJL = 30 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical bidirectional avalanche behavior - no polarity marking required. Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns) to ESD and lightning-induced transients.
Rated for repetitive 0.01% duty cycle surges, it delivers 400 W peak pulse power up to 91 V and 300 W above that threshold. Thermal performance is defined by RθJA = 120 °C/W (ambient) and RθJL = 30 °C/W (lead), enabling reliable operation up to TJ = +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - maximum continuous reverse working voltage before clamping initiates |
| VBR (Breakdown Voltage) | 210 V min - guaranteed avalanche conduction onset at 1 mA test current |
| VC (Clamping Voltage at IPPM) | 274 V - maximum voltage seen across terminals during 274 A transient event |
| IPPM (Peak Pulse Current) | 274 A - surge current capability under 10/1000 µs waveform, derated above 25 °C |
| PPPM (Peak Pulse Power) | 400 W - transient energy absorption capacity at TA = 25 °C, 300 W above 91 V |
| TJ max. | +150 °C - maximum junction temperature for continuous operation and surge reliability |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Bidirectional configuration has no polarity marking.

|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V systems |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control modules and ADAS sensor interfaces |
| Glass passivated chip junction | Ensures stable VBR tolerance (±5%), low leakage (<1 µA at VWM), and long-term reliability |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free reflow profiles without preconditioning or dry-pack requirements |
| Low incremental surge resistance | Minimizes clamping overshoot and improves protection margin for sensitive downstream ICs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection 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 dense automotive PCB layouts; requires larger pad area and lower thermal budget | Select when existing layout uses SMB footprint or higher surge margin is needed via derating |
| SMCJ200CA | Higher PPPM (1500 W), same VWM/VBR, but SMC (DO-214AB) package - 3× larger footprint and 2× weight | Over-specified for 400 W use cases; adds cost and space where P4SMA200CAHE3/61 meets requirement | Choose only if system-level testing demands >1000 W surge headroom or legacy SMC footprint must be retained |

FAQ
What is the clamping voltage of P4SMA200CAHE3/61 at its rated peak pulse current?
The clamping voltage (VC) of P4SMA200CAHE3/61 is 274 V at its specified peak pulse current (IPPM) of 274 A under the 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees the maximum voltage imposed on protected circuitry during a worst-case transient event - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P4SMA200CAHE3/61 suitable for automotive applications?
Yes, P4SMA200CAHE3/61 is AEC-Q101 qualified (denoted by the HE3 suffix), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its construction - glass-passivated junction, MSL Level 1 rating, and operation up to +150 °C - satisfies rigorous automotive reliability and thermal cycling requirements.
Does P4SMA200CAHE3/61 have polarity markings?
No, P4SMA200CAHE3/61 is a bidirectional TVS diode and carries no polarity marking on the SMA (DO-214AC) package. Its symmetrical breakdown characteristic allows installation in either orientation - simplifying layout and eliminating risk of reverse placement during automated assembly.
What is the thermal resistance from junction to lead for P4SMA200CAHE3/61?
The typical thermal resistance from junction to lead (RθJL) for P4SMA200CAHE3/61 is 30 °C/W. This low value enables efficient heat transfer from the silicon die to the PCB copper pads during repetitive surge events - supporting sustained reliability in high-duty-cycle industrial environments without additional heatsinking.
How does the 400 W peak pulse power rating of P4SMA200CAHE3/61 apply across voltage ranges?
The 400 W peak pulse power rating of P4SMA200CAHE3/61 applies up to 91 V standoff voltage; above 91 V, the rating reduces to 300 W. This reflects physical power-handling limits of the SMA package and silicon die - confirmed in Figure 2 of the Vishay datasheet (Document Number: 88367) and verified under 10/1000 µs waveform conditions at TA = 25 °C.
