Product details
Overview
1.5KE220CA-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 220 V breakdown voltage (VBR = 209–231 V at 1 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 328 V at 4.6 A, and operates across –55 °C to +175 °C junction temperature. It protects MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5KE220CA-E3/54 datasheet, 1.5KE220CA-E3/54 pinout, 1.5KE220CA-E3/54 application, or 1.5KE220CA-E3/54 equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, JEDEC 1.5KE package details, thermal derating curves, and AEC-Q101-qualified alternatives - all critical for automotive, industrial, and telecom surge protection design.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity concerns, unlike unidirectional variants requiring cathode orientation.
Rated for 1500 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, it sustains repetitive surges when thermally managed via lead-to-ambient thermal resistance (RθJA = 75 °C/W) and junction-to-lead (RθJL = 15.4 °C/W). Standoff voltage is 185 V, reverse leakage ≤1 µA at VWM, and maximum clamping occurs at 328 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at 1 mA - defines precise clamping onset threshold for overvoltage detection |
| VWM | 185 V - maximum continuous working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 328 V at 4.6 A - actual clamped voltage during 1500 W transient, limiting downstream stress |
| PPPM | 1500 W - peak surge energy absorption capability per 10/1000 µs pulse |
| Junction Temp Range | –55 °C to +175 °C - supports under-hood automotive and industrial ambient conditions |
| Package | JEDEC 1.5KE - axial-leaded DO-201AD outline, compatible with through-hole PCB assembly |
| RoHS Compliance | E3 suffix - meets JESD 201 Class 1A whisker test and UL 94 V-0 flammability rating |
Pinout & Package
1.5KE220CA-E3/54 uses the standard JEDEC 1.5KE (DO-201AD) axial-leaded package: molded epoxy body, matte tin-plated leads, 0.375" (9.5 mm) lead length, and no polarity marking (bidirectional symmetry).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | No polarity dependence - either lead connects to protected line; identical clamping in both directions |
| Leads (both) | Thermal and current conduction path | Primary heat dissipation route; RθJL = 15.4 °C/W enables effective pulse energy transfer to PCB copper |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Lower PPPM (600 W), smaller SMB package (surface-mount), VC = 356 V @ 2.2 A | Preferred for space-constrained PCBs where 1500 W is not required; lacks axial-lead mechanical robustness | Select when board area is limited and surge energy is ≤600 W; verify thermal pad layout for SMB footprint |
| 1.5KE220CAHE3_B | Identical electrical specs; adds AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and enhanced traceability | Mandatory for automotive OEM designs requiring PPAP documentation and qualification evidence | Choose for automotive production programs; E3/54 is commercial-grade only and not AEC-Q101 certified |
Compared with 1.5KE220CA-E3/54, SMBJ220CA trades peak power and mounting rigidity for compactness, while 1.5KE220CAHE3_B provides identical protection with automotive-grade process controls and documentation - making it the only drop-in qualified replacement.

FAQ
What is the clamping voltage of the 1.5KE220CA-E3/54 under a 1500 W surge?
The 1.5KE220CA-E3/54 clamps to 328 V at its peak pulse current of 4.6 A (10/1000 µs waveform). This value is measured per JEDEC standards and represents the maximum voltage imposed on protected circuitry during worst-case transient events. The 1.5KE220CA-E3/54 maintains this clamping performance across its full operating temperature range, ensuring consistent protection in automotive and industrial deployments.
Is the 1.5KE220CA-E3/54 suitable for automotive applications?
The 1.5KE220CA-E3/54 is commercial-grade and RoHS-compliant but not AEC-Q101 qualified. For automotive use, Vishay offers the 1.5KE220CAHE3_B variant - identical electrically but with full AEC-Q101 certification, enhanced whisker resistance, and production traceability. The 1.5KE220CA-E3/54 may be used in non-safety-critical aftermarket or prototyping contexts, but 1.5KE220CA-E3/54 is not approved for OEM automotive production without additional validation.
How does the bidirectional design of the 1.5KE220CA-E3/54 affect circuit placement?
The 1.5KE220CA-E3/54 has no polarity marking and functions identically in either orientation, simplifying PCB layout for AC-coupled lines, differential buses, or floating grounds. Unlike unidirectional TVS diodes, the 1.5KE220CA-E3/54 eliminates risk of reverse installation and avoids asymmetrical clamping behavior - critical for protecting balanced interfaces like RS-485 or Ethernet PHYs where voltage polarity reverses dynamically.
What is the thermal derating behavior of the 1.5KE220CA-E3/54 above 25 °C ambient?
The 1.5KE220CA-E3/54 follows a linear derating curve: power dissipation drops from 6.5 W at 25 °C to zero at 175 °C junction temperature. At 75 °C lead temperature, PD reduces to ~4.5 W (per Fig. 5). Designers must ensure adequate copper pour and lead length (0.375") to maintain RθJL = 15.4 °C/W; exceeding TJ max. risks permanent parametric shift or catastrophic failure during repeated surges.
Can the 1.5KE220CA-E3/54 be used in parallel to increase surge capacity?
Vishay explicitly permits parallel connection of 1.5KE220CA-E3/54 units to increase total peak pulse power, provided matched units are used and layout minimizes current imbalance (e.g., symmetric trace lengths, shared thermal plane). However, due to VBR tolerance (±5%), derating of total PPPM by ≥20% is recommended. The 1.5KE220CA-E3/54 does not require external balancing resistors but benefits from thermal coupling to equalize junction temperatures during multi-pulse events.
