Product details
Overview
1.5KE10CHE3/54 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 10 V breakdown voltage (VBR min/max = 9.5–10.5 V at 1 mA), 8.55 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 103 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD.
For engineers reviewing the 1.5KE10CHE3/54 datasheet, 1.5KE10CHE3/54 pinout, 1.5KE10CHE3/54 application, or 1.5KE10CHE3/54 equivalent, this part is selected for robust, low-clamping-voltage transient suppression in automotive body electronics, industrial I/O modules, and telecom power supply inputs where JEDEC-standard 1.5KE package compatibility and AEC-Q101 qualification (HE3 suffix variant) are required.
Technical Context
The 1.5KE10CHE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response time (<1 ns) and low incremental surge resistance to clamp fast-rising transients before downstream components experience overstress. Its unidirectional polarity enables cathode-referenced placement on positive supply rails, with reverse leakage limited to 10 µA at VWM.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting operation from –55 °C to +175 °C junction temperature. The device meets JESD 22-B106 solder dip (275 °C, 10 s) and JESD 201 Class 1A whisker testing (E3 suffix), and is RoHS-compliant per UL 94 V-0 molded epoxy packaging.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Lower PPPM (600 W), smaller SMB package (surface-mount), VC = 17 V at 34.6 A | Preferred for space-constrained PCBs; not suitable for 1500 W surge events | Select when board area is limited and surge threat level is ≤600 W (e.g., USB port protection) |
| 1.5KE10A-E3/54 | Same electrical specs and DO-201AD package, but commercial-grade (non-AEC-Q101 qualified) | Approved for industrial/commercial use only; excluded from automotive production | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with 1.5KE10CHE3/54, SMBJ10A offers compact SMT integration but sacrifices 60% peak power handling, while 1.5KE10A-E3/54 matches form-fit-function but lacks automotive qualification - making 1.5KE10CHE3/54 the sole choice for AEC-Q101-compliant 1500 W unidirectional TVS protection in harsh environments.

FAQ
What is the clamping voltage of the 1.5KE10CHE3/54 under maximum surge conditions?
The 1.5KE10CHE3/54 exhibits a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 103 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures downstream components see no more than 14.5 V during transient events - critical for protecting 5 V and 3.3 V logic devices. The 1.5KE10CHE3/54 achieves this with low dynamic impedance and sub-nanosecond response.
Is the 1.5KE10CHE3/54 suitable for automotive applications?
Yes, the 1.5KE10CHE3/54 is AEC-Q101 qualified (denoted by the HE3 suffix), making it approved for automotive use in engine control units, body electronics, and infotainment systems. It meets rigorous stress tests including temperature cycling, humidity bias, and mechanical shock. The 1.5KE10CHE3/54 also supports solder reflow profiles compliant with JESD 22-B106 and whisker resistance per JESD 201 Class 1A - confirming suitability for under-hood and cabin environments.
How does the 1.5KE10CHE3/54 differ from the standard 1.5KE10A-E3/54?
The 1.5KE10CHE3/54 and 1.5KE10A-E3/54 share identical electrical parameters (VBR, VWM, VC, PPPM) and DO-201AD packaging, but differ in qualification: the "H" in HE3 indicates AEC-Q101 qualification, while the base E3 version is commercial-grade only. The 1.5KE10CHE3/54 undergoes additional automotive-specific reliability testing - making it mandatory for Tier 1 automotive designs where 1.5KE10CHE3/54 compliance is contractually required.
What is the maximum operating temperature for the 1.5KE10CHE3/54?
The 1.5KE10CHE3/54 has a maximum junction temperature (TJ) rating of +175 °C and operates across –55 °C to +175 °C. This wide range supports deployment in high-ambient environments such as automotive engine compartments or industrial motor drives. Derating curves in the Vishay datasheet (Fig. 2 and Fig. 5) define allowable power reduction above 25 °C ambient - essential for thermal design validation of the 1.5KE10CHE3/54 in sealed enclosures.
Can the 1.5KE10CHE3/54 be used in bidirectional configurations?
No, the 1.5KE10CHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Bidirectional variants like 1.5KE10CA exist but are electrically distinct - they conduct in both directions and lack cathode marking. Using 1.5KE10CHE3/54 in a bidirectional circuit would result in forward conduction during negative transients, potentially damaging the device or failing to protect. Always verify polarity designation before selecting the 1.5KE10CHE3/54 for a given application.
