Product details
Overview
P6KE220CHE3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 209 V to 231 V breakdown voltage (VBR), 185 V stand-off voltage (VWM), 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used for protecting automotive sensor interfaces and industrial I/O lines against ESD and inductive switching surges.
For engineers reviewing the P6KE220CHE3/73 datasheet, P6KE220CHE3/73 pinout, P6KE220CHE3/73 application, or P6KE220CHE3/73 equivalent, this device is selected for robust overvoltage protection where bi-directional clamping, AEC-Q101 qualification, and low thermal resistance (20 °C/W junction-to-lead) are required in space-constrained PCB layouts.
Technical Context
The P6KE220CHE3/73 operates as a bi-directional avalanche diode, symmetrically clamping both positive and negative transients above its VBR threshold without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), enabling suppression of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5).
It delivers 600 W peak pulse power under 10/1000 μs waveform with 0.01 % duty cycle, derated linearly above 25 °C ambient per Fig. 2, and maintains clamping performance across -55 °C to +175 °C operating junction temperature range - validated for automotive-grade reliability per AEC-Q101.

FAQ
What is the polarity configuration of P6KE220CHE3/73?
The P6KE220CHE3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics - neither lead is marked as anode or cathode, and it clamps transients equally in both directions. This eliminates polarity concerns during placement and simplifies design for AC-coupled or differential signal lines. The 'CA' suffix in the full part number explicitly denotes bi-directional functionality, confirmed in Vishay Document 88369.
Does P6KE220CHE3/73 meet automotive qualification standards?
Yes, the P6KE220CHE3/73 carries the HE3 suffix indicating AEC-Q101 qualification - verified per stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD. This certification is documented in Vishay's official datasheet revision 18-Sep-12 (Document Number: 88369), confirming suitability for under-hood and body electronics applications.
What is the maximum clamping voltage of P6KE220CHE3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE220CHE3/73 is 328 V, measured at 1.8 A peak pulse current using the standard 10/1000 μs waveform. This value is specified in the Electrical Characteristics table on page 2 of Vishay Document 88369 and represents the upper voltage limit imposed on protected circuitry during worst-case transient events.
How does the thermal resistance of P6KE220CHE3/73 impact PCB layout?
The P6KE220CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning efficient heat transfer relies on short, wide copper traces connecting its leads to internal ground or thermal planes. Unlike devices with high RθJA, it does not require large external heatsinks - but lead length must be minimized to maintain thermal performance and avoid derating penalties above 25 °C ambient.
Is P6KE220CHE3/73 RoHS compliant and halogen-free?
Yes, the HE3 suffix confirms P6KE220CHE3/73 is RoHS-compliant per Directive 2011/65/EU and meets JEDEC JS709A halogen-free requirements. Vishay certifies all HE3-marked parts for both material compliance standards in Document 91000, with matte tin plating and UL 94 V-0 epoxy molding compound fully aligned with environmental regulations for automotive and industrial markets.
