Product details
Overview
1.5KE220HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 209 V to 231 V breakdown voltage (VBR), 185 V maximum standoff voltage (VWM), 328 V clamping voltage 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 in industrial power supplies and automotive ECUs.
For engineers reviewing the 1.5KE220HE3/54 datasheet, 1.5KE220HE3/54 pinout, 1.5KE220HE3/54 application, or 1.5KE220HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), RoHS-compliant HE3 packaging, and real-world clamping behavior under lightning-surge transients per IEC 61000-4-5.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse rating is defined with a 10/1000 µs waveform at 0.01 % duty cycle, and it maintains stable clamping up to TJ = 175 °C with derating per Fig. 2 of the datasheet.
The device supports 200 A non-repetitive forward surge current (IFSM) and exhibits 3.5 V max forward voltage at 100 A - critical for minimizing conduction loss during overvoltage events. Its RθJA = 75 °C/W and RθJL = 15.4 °C/W values confirm suitability for lead-mounted PCB layouts without heatsinking in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Low clamping ratio (VC/VBR ≈ 1.52) | Minimizes overvoltage overshoot during fast transients, protecting 200 V-rated MOSFETs and gate drivers |
| Matte tin plating, J-STD-002 compliant | Ensures robust solderability and intermetallic formation control on FR-4 and metal-core PCBs |
Applications
| Industrial Power Supply Protection | Automotive ECU Input Protection |
|---|---|
Use Scenario: 24 V DC input stage of programmable logic controllers exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: Clamps 10/1000 µs surges to ≤328 V, preventing damage to 36 V-input buck regulators and ensuring >100,000-cycle surge endurance. |
Use Scenario: LIN bus or sensor supply line in engine control units subjected to ISO 7637-2 Pulse 1/2a/5a. IC Role / Device Role / Timing Role: Standoff protection element on 12 V sensor feed, absorbing repetitive low-energy spikes without degradation. Use Value: Maintains <1 µA leakage at 185 V VWM, preserving sleep-mode current budget while surviving 1000+ surge events per AEC-Q101 test plan. |
| Telecom Line Interface Protection | Motor Drive Gate Driver Protection |
Use Scenario: Primary-side protection on PoE-powered Ethernet switches handling induced lightning surges on outdoor cabling. IC Role / Device Role / Timing Role: First-stage shunt protector on 48 V PSE output, coordinated with secondary GDT or MOV stages. Use Value: Sub-1 ns response time captures fast-rising edge of 8/20 µs lightning waveforms, limiting let-through energy to downstream SiC FETs. |
Use Scenario: High-side gate drive supply rail in 3-phase inverter modules where IGBT turn-off induces VCE overshoot. IC Role / Device Role / Timing Role: Clamp diode across bootstrap capacitor to suppress negative-going transients during shoot-through prevention. Use Value: Withstands 200 A IFSM, enabling direct placement near gate driver ICs without series fusing or current-limiting resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | DO-214AA package, 200 W lower PPPM (1300 W), same VBR range but higher VC (356 V) | Surface-mount only; unsuitable for through-hole legacy designs or high-thermal-mass chassis mounts | Select when board space is constrained and thermal management via copper pour is feasible. |
| 1.5KE220A-E3/54 | Same package and electrical specs, but commercial-grade (non-AEC-Q101 qualified), no HE3 whisker testing | Limited to non-automotive applications; not approved for under-hood or safety-critical ECUs | Choose for cost-sensitive industrial controls where automotive qualification is unnecessary. |
Compared with 1.5KE220HE3/54, SMBJ220A trades package compatibility and surge margin for SMT footprint efficiency, while 1.5KE220A-E3/54 retains mechanical and electrical equivalence but omits automotive process validation - making the HE3 variant the sole choice for AEC-Q101-compliant deployments.

FAQ
What is the clamping voltage of the 1.5KE220HE3/54 under a 10/1000 µs surge?
The 1.5KE220HE3/54 clamps to a maximum of 328 V at its rated peak pulse current of 4.6 A using the standardized 10/1000 µs waveform. This value is measured per Figure 7 in the Vishay datasheet 88301 and reflects worst-case incremental clamping behavior at TA = 25 °C. Engineers should apply derating curves (Fig. 2) for elevated ambient temperatures.
Is the 1.5KE220HE3/54 AEC-Q101 qualified?
Yes, the 1.5KE220HE3/54 is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS compliance and AEC-Q101 qualification per Note (2) on page 3 of Vishay document 88301, covering devices from 1.5KE6.8AHE3_B to 1.5KE220AHE3_B. This qualification includes stress testing for temperature cycling, humidity, and surge endurance required for automotive under-hood use.
What does the "/54" in 1.5KE220HE3/54 indicate?
The "/54" denotes the preferred package code per Vishay's ordering information table on page 3 of datasheet 88301. It specifies 13-inch diameter paper tape and reel packaging with a base quantity of 1400 units. This format enables automated pick-and-place assembly and is distinct from bulk or ammo-pack alternatives.
Can the 1.5KE220HE3/54 be used in bidirectional configurations?
No, the 1.5KE220HE3/54 is unidirectional only. Bidirectional variants in the 1.5KE family carry the "CA" suffix (e.g., 1.5KE220CA), and the datasheet explicitly states that bidirectional types are available only up to 1.5KE220CA. Using the unidirectional 1.5KE220HE3/54 in reverse-biased AC applications risks catastrophic failure due to lack of symmetrical breakdown.
What is the thermal resistance from junction to lead (RθJL) for the 1.5KE220HE3/54?
The 1.5KE220HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, as specified in the Thermal Characteristics table on page 3 of Vishay datasheet 88301. This value assumes 0.375 inch (9.5 mm) lead length and is critical for estimating temperature rise during repetitive surge events - especially when mounted directly to a metal chassis or heat-spreading copper plane.
