Product details
Overview
P4KE200-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 171 V stand-off voltage (VWM), 190–210 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 μs), and clamps to ≤274 V at 1.5 A peak pulse current - deployed in automotive power supply rail protection and industrial sensor interface circuits.
For engineers reviewing the P4KE200-E3/73 datasheet, P4KE200-E3/73 pinout, P4KE200-E3/73 application, or P4KE200-E3/73 equivalent, key selection criteria include verified clamping voltage under 10/1000 μs surge, unidirectional polarity with cathode band marking, DO-41 mechanical compatibility, AEC-Q101 qualification status, and thermal resistance (RθJL = 66 °C/W) for board-level thermal design.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protection device, triggered when reverse voltage exceeds its 190–210 V breakdown range. Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance during transient events.
It handles non-repetitive 10/1000 μs surges up to 400 W with 1.5 A peak pulse current, and supports 40 A 8.3 ms half-sine forward surge (unidirectional only). Junction temperature range spans –55 °C to +175 °C, with thermal resistance of 66 °C/W (junction-to-lead) enabling direct PCB trace heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - maximum continuous reverse operating voltage before conduction begins |
| VBR (Breakdown Voltage) | 190–210 V at 1 mA - precise avalanche initiation threshold for reliable clamping onset |
| VC (Clamping Voltage) | ≤274 V at IPPM = 1.5 A - limits downstream circuit voltage during surge, protecting ICs and MOSFETs |
| PPPM (Peak Pulse Power) | 400 W (10/1000 μs waveform) - defines transient energy absorption capacity per event |
| IFSM (Surge Current) | 40 A (8.3 ms half-sine) - withstands high-energy inductive switch-off spikes without failure |
| RθJL (Thermal Resistance) | 66 °C/W - enables thermal management via lead conduction; critical for sustained surge duty cycling |
| TJ max. | +175 °C - supports operation in under-hood automotive and high-ambient industrial environments |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads; RoHS-compliant (E3 suffix), JESD 201 Class 1A whisker tested.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., 24 V rail or sensor input); conducts during overvoltage to clamp |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 400 W peak pulse power (10/1000 μs) | Provides robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3/4 transients |
| AEC-Q101 qualified (E3 suffix variant is commercial; HE3 is AEC-Q101) | P4KE200-E3/73 is RoHS-compliant commercial grade; HE3 variant required for automotive-grade deployment |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving clamping precision |
| UL 94 V-0 compliant molding compound | Meets flammability safety requirements for enclosed industrial and automotive control modules |
Applications

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 | DO-214AA package; 200 V VBR; 600 W PPPM; lower RθJA (50 °C/W) but higher VC (324 V) | Better suited for space-constrained SMT layouts; less effective clamping than P4KE200-E3/73 for tight voltage margins | Select SMBJ200A when board real estate is limited and clamping voltage margin >50 V is acceptable |
| 1.5KE200A | DO-201AD package; same VBR/VC specs; 1500 W PPPM; higher IPPM (7.2 A); larger footprint and weight | Used where higher single-event energy handling is required (e.g., heavy-duty industrial motor drives) | Choose 1.5KE200A only if system-level testing confirms need for >400 W surge rating; otherwise P4KE200-E3/73 offers optimal cost-size-performance balance |
Compared with SMBJ200A and 1.5KE200A, the P4KE200-E3/73 delivers tighter clamping (274 V vs. 324 V/274 V), lower thermal resistance to lead (66 °C/W), and proven DO-41 through-hole reliability - making it preferred for cost-sensitive, thermally constrained, and legacy-compatible designs requiring precise voltage limiting.

FAQ
What is the polarity configuration of the P4KE200-E3/73?
The P4KE200-E3/73 is a unidirectional TVS diode: the banded end denotes the cathode and must be connected to the line being protected, while the anode connects to ground or the lower-potential reference. This configuration allows forward conduction only during negative transients - unlike bidirectional variants (e.g., P4KE200CA) that protect both polarities.
Is the P4KE200-E3/73 AEC-Q101 qualified?
No - the P4KE200-E3/73 carries the E3 suffix, indicating RoHS-compliant commercial grade with JESD 201 Class 1A whisker testing. For AEC-Q101 qualification, the correct part is P4KE200AHE3/73 (HE3 suffix), which undergoes full automotive stress testing including temperature cycling, humidity bias, and accelerated life validation.
What is the maximum clamping voltage of the P4KE200-E3/73 under surge conditions?
The P4KE200-E3/73 has a maximum clamping voltage (VC) of 274 V at 1.5 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet (Document Number 88365, Rev. 16-Sep-2021) and defines the upper voltage limit imposed on protected circuitry during transient events.
Can the P4KE200-E3/73 be used in bidirectional protection applications?
No - the P4KE200-E3/73 is strictly unidirectional. Bidirectional protection requires a CA-suffixed variant such as P4KE200CA, which lacks polarity marking and conducts symmetrically in both directions. Using P4KE200-E3/73 for bidirectional threats would leave the positive half-cycle unprotected and risk device failure.
What is the thermal resistance specification for the P4KE200-E3/73?
The P4KE200-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with lead length L = 10 mm. This parameter is critical for estimating junction temperature rise during repetitive surge events and informs PCB copper pour design around the leads for effective heat dissipation.
