For engineers reviewing the 1.5KE220-E3/54 datasheet, 1.5KE220-E3/54 pinout, 1.5KE220-E3/54 application, or 1.5KE220-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package dimensions, clamping behavior under surge conditions, thermal resistance data (RθJA = 75 °C/W), and direct alternative part comparisons for ESD and lightning transient suppression design validation.
Technical Context
The 1.5KE220-E3/54 uses a glass passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-grounded placement on DC rails, with a 3.5 V forward voltage at 100 A surge - confirmed for devices ≤1.5KE220A per datasheet note (3).
It complies with JEDEC DO-201AD mechanical standard (Case Style 1.5KE), supports 275 °C solder dip (10 s max), meets UL 94 V-0 flammability, and is RoHS-compliant (E3 suffix). The device is commercial grade only - not AEC-Q101 qualified, unlike HE3-suffix variants.

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 (smaller footprint), 200 W lower PPPM (1300 W), same VBR range (209–231 V), higher RθJA (100 °C/W) | Better suited for space-constrained PCBs but requires thermal relief for >1 pulse/sec duty cycle | Select SMBJ220A when board area is limited and surge repetition rate is low; verify thermal performance with layout simulation. |
| 1.5KE220AHE3_B | Same 1.5KE package and electrical specs, but AEC-Q101 qualified, HE3 whisker-tested, and rated for automotive under-hood use | Required for production automotive modules where qualification compliance is mandatory | Choose 1.5KE220AHE3_B for Tier 1 automotive designs; 1.5KE220-E3/54 remains valid for cost-sensitive commercial industrial applications. |
Compared with SMBJ220A, 1.5KE220-E3/54 delivers 15% higher surge power headroom and lower thermal resistance for sustained reliability in high-temperature enclosures; versus 1.5KE220AHE3_B, it lacks automotive qualification but offers identical clamping performance at lower cost for non-automotive use cases.

FAQ
What is the breakdown voltage tolerance for 1.5KE220-E3/54?
The 1.5KE220-E3/54 has a specified breakdown voltage range of 209 V to 231 V at 1 mA test current, representing a ±5 % tolerance around the nominal 220 V rating. This tight tolerance ensures predictable clamping onset across production lots and supports reliable coordination with upstream fuses or downstream IC absolute maximum ratings. All units of 1.5KE220-E3/54 meet this specification per Vishay Document Number 88301, Revision 09-Aug-2022.
Is 1.5KE220-E3/54 suitable for bidirectional transient protection?
No, 1.5KE220-E3/54 is a unidirectional TVS diode, indicated by the absence of "CA" suffix. Bidirectional versions (e.g., 1.5KE220CA) are available only up to 220 V VBR, but 1.5KE220-E3/54 must be used with correct polarity - cathode tied to the protected line, anode to ground. Using it in reverse-biased AC applications will result in forward conduction and failure. For bidirectional protection, specify 1.5KE220CA or equivalent.
What is the maximum clamping voltage of 1.5KE220-E3/54 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE220-E3/54 is 328 V at its rated peak pulse current (IPPM) of 4.6 A, measured with a 10/1000 µs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case surge events and is critical for ensuring downstream components remain within their absolute maximum voltage ratings. Data is confirmed in Table "ELECTRICAL CHARACTERISTICS" of Vishay document 88301.
Does 1.5KE220-E3/54 comply with AEC-Q101 automotive qualification?
No, 1.5KE220-E3/54 is commercial grade only and not AEC-Q101 qualified. The "E3" suffix denotes RoHS compliance and JESD 201 Class 1A whisker testing, but automotive qualification requires the "HE3" suffix (e.g., 1.5KE220AHE3_B). Per datasheet note on page 2, AEC-Q101 qualification applies only to HE3-suffix parts in the 1.5KE6.8A–1.5KE220A range. Engineers designing for automotive applications must select the HE3 variant instead of 1.5KE220-E3/54.
What is the thermal resistance and how does it affect PCB layout for 1.5KE220-E3/54?
The 1.5KE220-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, measured with standard JEDEC test conditions (no heatsink, 0.375" lead length). This value means each watt of sustained power dissipation raises junction temperature by 75 °C above ambient. For reliable long-term operation, PCB layout must provide adequate copper pour on both anode and cathode pads, avoid narrow traces, and maintain ≥25 mm² of 2 oz copper per terminal to approximate the test condition. Exceeding TJ max. of +175 °C risks parametric shift or failure.
