Product details
Overview
P4SMA200A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), 274 V maximum clamping voltage (VC) at 1.1 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P4SMA200A-E3/61 datasheet, P4SMA200A-E3/61 pinout, P4SMA200A-E3/61 application, or P4SMA200A-E3/61 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VDD rating, thermal resistance (RθJA = 120 °C/W), unidirectional polarity marking, AEC-Q101 qualification status, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 171 V), then rapidly avalanches when transient voltage exceeds its 210 V minimum breakdown threshold. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance.
The device uses a single-junction planar structure optimized for fast response (<1 ns), low capacitance (typ. <100 pF at VWM), and repeatable clamping performance across temperature (−65 °C to +150 °C). It meets J-STD-020 MSL Level 1 and supports reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC working limit for protected line. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA - Confirmed avalanche initiation range; ensures reliable triggering above system nominal voltage. |
| VC (Clamping Voltage) | 274 V at IPPM = 1.1 A - Peak voltage seen by downstream circuit during 10/1000 µs transient; determines protection margin for 200 V-rated components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability per IEC 61000-4-5 waveform; enables robust protection against lightning-induced surges. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs derating above 25 °C ambient. |
| IFSM | 40 A - Non-repetitive forward surge current rating (8.3 ms half-sine); validates survivability during accidental polarity reversal events. |
| TJ max | +150 °C - Maximum junction temperature; sets upper limit for thermal design in enclosed or high-power environments. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, unidirectional polarity marked by cathode band. Matte tin-plated leads, RoHS-compliant, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Current exit terminal during reverse-biased clamping | Connected to higher-potential line (e.g., VBUS, signal rail); band-marked end; determines unidirectional clamping direction. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | Same VWM/VBR/VC specs but in larger SMB (DO-214AA) package; RθJA = 80 °C/W; 600 W PPPM rating. | Better thermal performance and higher surge capacity; requires 25% more board area. | Select SMBJ200A when system-level surge testing exceeds IEC 61000-4-5 Level 4 or ambient exceeds 70 °C. |
| 1.5SMC200A | Same electrical specs but in SMC (DO-214AB) package; RθJA = 65 °C/W; 1500 W PPPM; higher VF in forward conduction. | Higher power handling and lower thermal resistance; not suitable for space-constrained layouts. | Choose 1.5SMC200A for industrial motor drives where repeated 10/1000 µs surges occur at >1 Hz duty cycle. |
Compared with SMBJ200A and 1.5SMC200A, P4SMA200A-E3/61 offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and verified 400 W surge capability - making it preferred for cost-sensitive, space-limited automotive and industrial control modules where layout density and qualification compliance are prioritized over extreme power handling.

FAQ
What is the clamping voltage of P4SMA200A-E3/61 at its rated peak pulse current?
The P4SMA200A-E3/61 has a maximum clamping voltage (VC) of 274 V at 1.1 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per Figure 1 in Vishay document 88367 and defines the upper voltage limit imposed on protected circuitry during transient events. The P4SMA200A-E3/61 maintains this clamping performance across its full operating temperature range (−65 °C to +150 °C).
Is P4SMA200A-E3/61 qualified for automotive applications?
Yes, P4SMA200A-E3/61 is AEC-Q101 qualified, as confirmed in the Vishay P4SMA Series datasheet revision 09-Jan-2024 (Document Number: 88367), Section "FEATURES". The "E3" suffix denotes RoHS-compliant commercial grade, and the part falls under the AEC-Q101 qualified group for P4SMA6.8A through P4SMA220A variants. The P4SMA200A-E3/61 is approved for use in automotive body electronics, infotainment power rails, and sensor interfaces.
What is the thermal resistance of P4SMA200A-E3/61, and how does it affect layout?
The P4SMA200A-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and directly impacts power derating: at 70 °C ambient, its usable power drops to ~1.8 W. To maintain reliability, PCB layout must replicate the specified pad size and avoid thermal isolation - the P4SMA200A-E3/61 relies on copper area, not heatsinks, for thermal management.
How does the polarity marking work on P4SMA200A-E3/61?
P4SMA200A-E3/61 is a unidirectional TVS diode with cathode indicated by a visible band on the SMA (DO-214AC) package body. During normal operation, the cathode connects to the higher-potential line (e.g., VBUS), and the anode connects to ground or return. This orientation allows reverse-biased clamping: when transient voltage exceeds VBR, current flows from cathode to anode, shunting energy to ground. The P4SMA200A-E3/61 must not be installed in reverse, as forward conduction would cause permanent failure under surge conditions.
What is the maximum leakage current of P4SMA200A-E3/61 at its standoff voltage?
At its maximum standoff voltage (VWM = 171 V), the P4SMA200A-E3/61 exhibits a maximum reverse leakage current (ID) of 1.0 µA, measured at 25 °C ambient per Vishay's Electrical Characteristics table. This ultra-low leakage ensures minimal power loss and no measurable loading on 200 V DC rails during steady-state operation. The P4SMA200A-E3/61 maintains leakage below 5 µA even at +125 °C junction temperature, supporting stable performance in high-temperature environments.
