FFF CompatibilityMatches the 2-pin axial through-hole DO-201 footprint exactly with a bidirectional non-polarized pinout.The body dimensions, lead spacing, and packaging style are completely identical to the STMicroelectronics baseline.Features identical peak pulse power of 1500W and a 175°C maximum junction temperature rating.Shares the identical DO-201 axial through-hole package and pin configuration.Physical dimensions and lead diameter conform to the standard DO-201AA (DO-27) specification.Meets all critical TVS ratings with identical peak pulse power and voltage limits.
AI Summary

1.5KE36CA by STMicroelectronics: 64.3V Clamp 156A (8/20µs) Ipp Tvs Diode Through Hole DO-201.

This is an exact, highly reliable drop-in replacement from a top-tier manufacturer of circuit protection devices. It matches all major electrical and physical properties of the obsolete STMicroelectronics original.

  • Direct industry-standard cross-reference part number
  • Identical electrical specifications: 30.8V reverse standoff, 34.2V breakdown min, and 49.9V clamping maximum
  • Same DO-201 axial through-hole footprint with identical 2-pin bidirectional configuration
  • The minimum storage/operating temperature starts at -55°C instead of STMicroelectronics' -65°C rating.

Part of Vishay's established TransZorb series, this device provides a seamless transition for legacy designs requiring high-quality axial transient suppression. The -E3/54 suffix represents the lead-free commercial grade packaged on a standard tape-and-reel.

  • Widely available and actively in production
  • Matches the 30.8V standoff, 1500W peak pulse power, and 49.9V clamp rating exactly
  • Same 2-pin bidirectional axial package with no polarity requirements
  • The minimum operating junction temperature starts at -55°C compared to ST's -65°C specification.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.

Frequently asked questions

Yes. The STMicroelectronics 1.5KE36CA is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
