Product details
Overview
ICTE12/54 from Vishay Semiconductors is a unidirectional 12 V stand-off transient voltage suppressor (TVS) diode in the 1.5KE case style, rated for 1500 W peak pulse power (10/1000 µs), 70 A peak pulse current, and clamping voltage of 16.1 V at 1.0 A and 16.5 V at 10 A - designed for robust overvoltage protection on DC power rails and industrial control inputs.
For engineers reviewing the ICTE12/54 datasheet, ICTE12/54 pinout, ICTE12/54 application, or ICTE12/54 equivalent, key selection criteria include verified clamping performance at 10 A, JEDEC-registered breakdown voltage (14.1 V min), low leakage (2.0 µA max at VWM), and axial-leaded 1.5KE package compatibility with high-temperature soldering (265 °C/10 s).
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to deliver fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is characterized by a 1.15× ratio of VC(10 A)/VBR, meeting JEDEC-standardized TVS performance for industrial-grade surge immunity.
The ICTE12/54 is thermally rated for TJ = –55 to +175 °C, with steady-state power dissipation of 6.5 W at TL = 75 °C and 0.375" lead length. It supports non-repetitive 8.3 ms half-sine surges up to 200 A (IFSM), and exhibits <2.0 µA reverse leakage at 12 V stand-off.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ12A | Surface-mount SMB package; lower PPPM = 600 W; VC = 19.9 V at 30 A | Designed for PCB space-constrained designs; not suitable for high-energy 1500 W surges | Select ICTE12/54 when axial-leaded mounting and full 1500 W rating are required; choose SMBJ12A only for compact layouts with lower surge exposure. |
| 1N6376 | Same electrical specs and 1.5KE package; differs only in packaging code (bulk vs. reel); identical die and construction | No functional difference; 1N6376 is the JEDEC-standard part number for ICTE-12 | ICTE12/54 and 1N6376 are electrically and mechanically interchangeable; ICTE12/54 denotes 1.4K/reel tape-and-reel packaging per code "54". |
Compared with SMBJ12A and 1N6376, the ICTE12/54 provides identical clamping performance to 1N6376 but in tape-and-reel form for automated assembly, while offering 2.5× higher surge power than SMBJ12A - making it optimal for high-reliability industrial power rail protection where axial leads and proven 1500 W capability are mandatory.

FAQ
What is the clamping voltage of ICTE12/54 at 10 A?
The ICTE12/54 has a maximum clamping voltage of 16.5 V at 10 A peak pulse current (10/1000 µs waveform), as specified in Table 1 of Vishay Document 88356. This value ensures protected circuits remain below critical voltage thresholds during standardized surge events, and is measured with the device mounted per JEDEC test conditions.
Is ICTE12/54 unidirectional or bidirectional?
ICTE12/54 is a unidirectional transient voltage suppressor, confirmed by its listing in Table 1 (Unidirectional Types) and absence from Table 2. It features a cathode band marking and is intended for DC rail protection where polarity is fixed - unlike bidirectional variants such as ICTE-12C which appear in separate rows with "C" suffix.
What does the "/54" suffix mean in ICTE12/54?
The "/54" in ICTE12/54 refers to Vishay's packaging code indicating 1.4K units per 13" paper tape reel (52 mm horizontal pitch), with 4.2K per carton. This is distinct from bulk (code 51) or ammo-pack (code 73) options, and does not affect electrical or thermal specifications of the ICTE12/54 device itself.
Can ICTE12/54 replace 1N6376 in existing designs?
Yes - ICTE12/54 and 1N6376 share identical electrical characteristics, package (1.5KE), pinout, and thermal ratings. The ICTE12/54 is the same silicon die in tape-and-reel packaging (code 54), whereas 1N6376 typically ships in bulk. No layout or schematic changes are needed when substituting ICTE12/54 for 1N6376.
What is the maximum operating temperature for ICTE12/54?
The ICTE12/54 is rated for an operating junction and storage temperature range of –55 °C to +175 °C, as stated in the Maximum Ratings table. This allows deployment in under-hood automotive, industrial furnace controls, and outdoor telecom enclosures where ambient temperatures exceed 105 °C.
