Product details
Overview
1.5KE220CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 209 V to 231 V breakdown voltage (VBR) at 1 mA, 185 V maximum working peak reverse 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 range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1.5KE220CHE3/54 datasheet, 1.5KE220CHE3/54 pinout, 1.5KE220CHE3/54 application, or 1.5KE220CHE3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal derating curves, and AEC-Q101-qualified alternatives for automotive-grade design validation.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going transients, with a 3.5 V forward voltage at 100 A surge current - critical for minimizing conduction loss during high-energy events.
The device complies with JEDEC standard 1.5KE case outline and supports 13" paper tape & reel packaging (E3/54). It is RoHS-compliant and qualified to AEC-Q101 for automotive applications, with thermal resistance of 15.4 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at 1 mA - defines precise voltage threshold where clamping initiates under controlled test conditions |
| VWM | 185 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets safe DC bias margin |
| VC @ IPPM | 328 V at 4.6 A (10/1000 µs) - actual clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 1500 W - peak transient energy absorption capability without failure; enables robust lightning/ESD immunity |
| TJ max. | +175 °C - allows operation in under-hood automotive environments and high-temperature industrial enclosures |
| RθJL | 15.4 °C/W - low thermal resistance from junction to lead enables effective heat dissipation into PCB copper |
| Package | JEDEC 1.5KE - axial-leaded DO-201AD package with matte tin-plated leads compliant to J-STD-002 solderability |
Pinout & Package
1.5KE220CHE3/54 uses the standard JEDEC 1.5KE (DO-201AD) axial package: molded epoxy body, color band indicating cathode terminal, matte tin-plated leads, UL 94 V-0 rated compound. Lead length is 0.375" (9.5 mm); diameter 0.210" (5.3 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to ground or low-side return path; conducts only during reverse-biased overvoltage events |
| Cathode | Protected line connection point | Connected to the line being safeguarded (e.g., 24 V rail input); blocks normal operation, conducts during overvoltage |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: 24 V battery-fed ECU power entry subjected to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary shunt clamping element placed directly at connector entry point to limit voltage excursion before LDO or DC-DC converter input. Use Value: Clamps to ≤328 V within <1 ns, preventing damage to 36 V-rated input stages while surviving repetitive 1500 W pulses. |
Use Scenario: 4–20 mA current loop interface exposed to field wiring induced transients in factory automation. IC Role / Device Role / Timing Role: Unidirectional TVS connected between signal line and local ground to suppress common-mode surges up to 1 kV. Use Value: Maintains signal integrity below 185 V stand-off while limiting clamp voltage to protect 24 V op-amp front-ends and ADC inputs. |
| Telecom DC Feeder Protection | Consumer Appliance Motor Drive Surge Absorption |
Use Scenario: -48 V telecom power feeders vulnerable to lightning-induced surges on outdoor cable runs. IC Role / Device Role / Timing Role: First-stage protector on power entry board, upstream of DC-DC converters and PMICs. Use Value: Absorbs 1500 W pulses without thermal runaway; RθJL = 15.4 °C/W ensures compatibility with minimal copper area. |
Use Scenario: Brushed DC motor driver PCB where inductive kickback generates >1 kV spikes across H-bridge FETs. IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals to clamp flyback voltage before it reaches gate drivers. Use Value: Fast <1 ns response prevents FET avalanche failure; 200 A IFSM rating handles repeated commutation surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A-E3/52 | DO-214AA (SMB) package; lower PPPM = 600 W; VC = 355 V @ 2.4 A; higher capacitance (~100 pF) | Preferred for space-constrained PCBs; unsuitable for ISO 7637-2 Pulse 5a due to lower power rating | Select when board area is limited and surge energy is ≤600 W; verify layout thermal relief for SMB footprint. |
| 1.5KE220AHE3_B | Same 1.5KE package and electrical specs; AEC-Q101 qualified with revision code "B"; identical VBR, VC, and PPPM | Drop-in replacement for automotive programs requiring documented AEC-Q101 compliance with traceable lot data | Use when full AEC-Q101 documentation (test reports, PPAP) is contractually required; same thermal and electrical behavior. |
Compared with 1.5KE220CHE3/54, SMBJ220A-E3/52 trades power handling for compactness, while 1.5KE220AHE3_B provides identical performance with formalized automotive qualification - enabling direct substitution where compliance reporting is mandatory.

FAQ
What is the clamping voltage of the 1.5KE220CHE3/54 under a 10/1000 µs surge?
The 1.5KE220CHE3/54 clamps to a maximum of 328 V when subjected to its rated peak pulse current of 4.6 A using the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the upper bound voltage imposed on the protected circuit during surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 1.5KE220CHE3/54 suitable for automotive applications?
Yes, the 1.5KE220CHE3/54 is AEC-Q101 qualified and explicitly listed in Vishay's qualified part list for the 1.5KE6.8AHE3_B to 1.5KE220AHE3_B family. Its -55 °C to +175 °C operating range, 200 A IFSM surge rating, and validated performance under temperature cycling and humidity testing make it appropriate for engine control units, body electronics, and ADAS power supplies.
How does the 1.5KE220CHE3/54 differ from bidirectional variants like 1.5KE220CA?
The 1.5KE220CHE3/54 is unidirectional, featuring a cathode band and conducting only during reverse-biased overvoltage events. In contrast, 1.5KE220CA is bidirectional with symmetrical clamping in both polarities and no polarity marking. Bidirectional types are limited to ≤220 V VBR; the 1.5KE220CHE3/54 shares identical VBR, VC, and PPPM but serves DC-coupled, ground-referenced protection schemes.
What is the thermal resistance specification for the 1.5KE220CHE3/54?
The 1.5KE220CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W. These values assume standard JEDEC test conditions (lead length 0.375", no heatsink). Effective PCB copper pour design can reduce thermal impedance, especially critical during repetitive surge events.
Can the 1.5KE220CHE3/54 be used in parallel to increase surge handling capacity?
Yes, the 1.5KE220CHE3/54 may be paralleled to distribute surge current, but matching VBR tolerances (±5%) and symmetric PCB layout are essential to ensure current sharing. Vishay recommends using matched lots and verifying clamping uniformity with pulse testing - mismatched units may cause one device to absorb disproportionate energy and fail prematurely.
