Product details
Overview
P4SMA200A-E3/5A 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 274 V maximum clamping voltage (VC) at 1.1 A peak pulse current (IPPM), designed to protect sensitive ICs and MOSFETs against inductive switching transients and lightning surges in industrial power supplies and telecom interfaces.
For engineers reviewing the P4SMA200A-E3/5A datasheet, P4SMA200A-E3/5A pinout, P4SMA200A-E3/5A application, or P4SMA200A-E3/5A equivalent, key selection criteria include unidirectional polarity, 400 W peak pulse power (10/1000 µs), 3.3 W steady-state power dissipation, AEC-Q101 qualification eligibility (via HE3/HM3 suffix variants), and RoHS-compliant matte tin plating compatible with J-STD-002 soldering standards.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, triggering when reverse voltage exceeds its breakdown threshold (190–210 V) to divert surge current away from downstream components. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance under repetitive 10/1000 µs transients.
Thermal performance is defined by 120 °C/W junction-to-ambient thermal resistance (RθJA) on standard 0.2" × 0.2" copper pads and 30 °C/W junction-to-lead (RθJL), enabling reliable operation up to 150 °C junction temperature. It meets MSL Level 1 per J-STD-020 with 260 °C reflow peak and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA - Voltage at which device enters controlled avalanche; ensures precise overvoltage threshold activation. |
| VC (Clamping Voltage) | 274 V at 1.1 A IPPM - Peak voltage seen by protected circuit during surge; limits stress on downstream ICs and MOSFETs. |
| PPPM (Peak Pulse Power) | 400 W (10/1000 µs waveform) - Surge energy-handling capacity; supports robust protection in telecom and industrial environments. |
| ID (Reverse Leakage) | 1.0 µA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature; enables use in enclosed, thermally constrained enclosures without derating. |
| Package | SMA (DO-214AC) - Surface-mount footprint with 5.28 mm length, 4.50 mm width, and 2.29 mm height; compatible with automated pick-and-place. |

Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24–48 V systems without external series impedance. |

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 (171 V) and VC (274 V), but SMB package (DO-214AA) with higher RθJA (150 °C/W) and lower IPPM (1.2 A) | Lower power density; suitable for space-constrained layouts where thermal pad area is limited | Select SMBJ200A only if board real estate is tighter than thermal budget allows for SMA mounting pads |
| 1.5SMC200A | Same electrical specs but larger SMC (DO-214AB) package with 100 °C/W RθJA and 1.3 A IPPM; higher PD (5.0 W) | Better thermal performance for high-duty-cycle surges; requires larger PCB footprint | Choose 1.5SMC200A when ambient temperature exceeds 85 °C or surge repetition rate exceeds 0.01 % duty cycle |
Compared with P4SMA200A-E3/5A, SMBJ200A trades thermal efficiency for smaller footprint, while 1.5SMC200A delivers superior heat dissipation at the cost of board area-making P4SMA200A-E3/5A the optimal balance of size, surge capability, and manufacturability for mid-volume industrial designs.

FAQ
What is the clamping voltage of P4SMA200A-E3/5A at its rated peak pulse current?
The P4SMA200A-E3/5A 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 Vishay Document 88367 and defines the upper voltage limit imposed on protected circuitry during surge events. The P4SMA200A-E3/5A maintains this clamping performance across its specified operating temperature range of -65 °C to +150 °C.
Is P4SMA200A-E3/5A RoHS-compliant and lead-free?
Yes, P4SMA200A-E3/5A is RoHS-compliant and lead-free, as confirmed by the "E3" suffix in its ordering code. The device uses matte tin-plated leads and complies with J-STD-002 solderability requirements. Its molding compound meets UL 94 V-0 flammability rating, and it satisfies JESD201 Class 2 whisker resistance testing. The P4SMA200A-E3/5A is not halogen-free; for halogen-free compliance, the M3 suffix variant (e.g., P4SMA200A-M3/5A) must be selected.
Can P4SMA200A-E3/5A be used in bidirectional configurations?
No, P4SMA200A-E3/5A is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Bidirectional operation requires the CA variant (e.g., P4SMA200CA). The P4SMA200A-E3/5A features a cathode band marking and conducts only in reverse breakdown; applying significant forward voltage may cause permanent damage. For AC line or differential signal protection, P4SMA200CA or dual-diode arrangements must be used instead of P4SMA200A-E3/5A.
What is the thermal resistance of P4SMA200A-E3/5A, and how does it affect layout design?
P4SMA200A-E3/5A 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, and 30 °C/W junction-to-lead (RθJL). These values require PCB layout with adequate copper pour on both anode and cathode pads to sustain 3.3 W steady-state power dissipation. Reducing pad size or omitting thermal vias increases RθJA and risks exceeding the 150 °C maximum junction temperature during repeated surges.
Does P4SMA200A-E3/5A meet automotive qualification standards?
The base P4SMA200A-E3/5A is commercial-grade and not AEC-Q101 qualified. However, Vishay offers automotive-qualified versions under the HE3 and HM3 suffixes (e.g., P4SMA200AHE3_A), which undergo full AEC-Q101 stress testing and are intended for automotive applications. The P4SMA200A-E3/5A itself lacks the required qualification documentation and test reports; for automotive use, engineers must specify the HE3 or HM3 variant-not P4SMA200A-E3/5A-to ensure compliance.
