Product details
Overview
1.5KE220C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in signal and power lines. It features a 209 V to 231 V breakdown voltage (VBR) at 1 mA, 185 V maximum standoff voltage (VWM), 328 V clamping voltage (VC) at 4.6 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5KE220C-E3/54 datasheet, 1.5KE220C-E3/54 pinout, 1.5KE220C-E3/54 application, or 1.5KE220C-E3/54 equivalent, this device serves as a robust, glass-passivated, RoHS-compliant TVS for industrial and automotive electronics where fast clamping (<1 ns), low incremental surge resistance, and AEC-Q101-qualified variants are critical selection criteria.
Technical Context
The 1.5KE220C-E3/54 implements a silicon avalanche junction structure optimized for bidirectional transient suppression without polarity marking. Its clamping behavior is defined by a 10/1000 µs waveform with 0.01% duty cycle, delivering stable VC = 328 V at IPPM = 4.6 A while maintaining <10 µA reverse leakage at VWM.
Thermal performance is characterized by RθJL = 15.4 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling reliable operation under repetitive surge conditions when mounted on PCB copper pours or leads per JESD 22-B106 soldering guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at 1 mA - defines minimum guaranteed clamping onset and maximum variation across production lot |
| VWM | 185 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 328 V at 4.6 A - peak clamped voltage during 1500 W transient, directly limiting stress on downstream components |
| PPPM | 1500 W (10/1000 µs) - energy-handling capacity sufficient for IEC 61000-4-5 Level 4 surges |
| TJ range | –55 °C to +175 °C - supports under-hood automotive and industrial ambient environments |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 rated epoxy body |
| Leakage @ VWM | <1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
Pinout & Package
1.5KE220C-E3/54 uses a two-terminal axial-leaded DO-201AD (Case Style 1.5KE) package with no polarity marking - consistent with its bidirectional function. Leads are matte tin-plated and compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | No functional distinction - either lead connects to protected line; enables placement without orientation check |
| Lead 1 / Lead 2 | Current path for surge conduction | Low-inductance path between PCB trace and junction; thermal dissipation via lead-to-PCB copper interface |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | DO-214AA package, 200 W PPPM, VC = 355 V @ 4.2 A - lower power, surface-mount | Used where board space is constrained and surge energy is limited to ≤200 W | Select SMBJ220CA only if layout prohibits axial-leaded devices and system-level testing confirms 200 W sufficiency. |
| 1.5KE220A-E3/54 | Unidirectional variant with cathode band marking; identical VBR, VWM, VC, and PPPM; same package | Required where polarity-sensitive circuits (e.g., DC bias rails) need asymmetric clamping | Choose 1.5KE220A-E3/54 when protecting unidirectional power paths - otherwise 1.5KE220C-E3/54 offers orientation-free placement. |
Compared with SMBJ220CA and 1.5KE220A-E3/54, the 1.5KE220C-E3/54 uniquely delivers 1500 W bidirectional clamping in an axial-leaded through-hole package, enabling higher surge margin and simplified assembly in legacy or high-reliability designs where orientation independence matters.

FAQ
What is the clamping voltage of the 1.5KE220C-E3/54 under standard test conditions?
The 1.5KE220C-E3/54 has a maximum clamping voltage (VC) of 328 V at a peak pulse current (IPPM) of 4.6 A, measured using a 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during a full 1500 W transient event and is confirmed in Vishay's Document Number 88301, page 2, Electrical Characteristics table.
Is the 1.5KE220C-E3/54 suitable for automotive applications?
Yes - while the base 1.5KE220C-E3/54 is commercial grade, the AEC-Q101-qualified variant 1.5KE220CAHE3_B is available. The 1.5KE220C-E3/54 shares identical electrical specs and package, and is commonly deployed in non-safety-critical automotive subsystems such as infotainment power rails and sensor interfaces where qualification is not mandated but robustness is required.
How does the 1.5KE220C-E3/54 differ from the unidirectional 1.5KE220A-E3/54?
The 1.5KE220C-E3/54 is bidirectional with no polarity marking, allowing installation in either orientation on AC-coupled or floating lines. The 1.5KE220A-E3/54 is unidirectional, marked with a cathode band, and intended for DC-biased applications. Both share identical VBR, VWM, VC, PPPM, and package dimensions - only polarity and marking differ.
What is the maximum operating temperature for the 1.5KE220C-E3/54?
The 1.5KE220C-E3/54 has a maximum junction temperature (TJ) of +175 °C and a storage temperature range of –55 °C to +175 °C. Its thermal resistance values - RθJL = 15.4 °C/W and RθJA = 75 °C/W - allow it to sustain repeated surges in high-ambient environments when properly mounted with adequate copper pour or lead heatsinking.
Does the 1.5KE220C-E3/54 meet RoHS and lead-free requirements?
Yes - the "E3" suffix indicates full compliance with RoHS Directive 2011/65/EU and JESD 201 Class 1A whisker resistance. The device uses matte tin-plated leads, UL 94 V-0 epoxy encapsulation, and contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits.
