Product details

Overview

1.5KE10-E3/54 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 9.5 V minimum breakdown voltage (V_BR), 8.55 V maximum standoff voltage (V_WM), 14.5 V clamping voltage at 10 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.

For engineers reviewing the 1.5KE10-E3/54 datasheet, 1.5KE10-E3/54 pinout, 1.5KE10-E3/54 application, or 1.5KE10-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under surge conditions, thermal resistance data, and RoHS-compliant commercial-grade sourcing status - all confirmed from Vishay Document #88301 (Rev. 09-Aug-2022).

Technical Context

This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its clamping action begins at 9.5 V (min V_BR) and limits voltage to ≤14.5 V at 10 A IPPM, enabling robust protection of downstream MOSFETs and ICs against inductive switching spikes and ESD events.

Rated for 1500 W peak pulse power with 10/1000 µs waveform and 0.01% duty cycle, it sustains 200 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits 3.5 V max forward voltage at 100 A - confirming suitability for high-energy transient suppression in 12 V and 24 V systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR (min)	9.5 V - Ensures reliable triggering above normal 8.55 V operating rail, preventing false clamping during transients.
V_WM	8.55 V - Maximum continuous reverse working voltage; defines upper limit of safe DC operation without leakage degradation.
V_C @ I_PPM	14.5 V - Clamped voltage at 10 A peak pulse; determines maximum stress imposed on protected circuitry.
P_PPM	1500 W - Peak pulse power handling capability with 10/1000 µs waveform; validates compliance with IEC 61000-4-5 Level 4 surge immunity.
I_FSM	200 A - Non-repetitive forward surge current rating (8.3 ms); supports protection against severe load dump events.
T_J max	+175 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments.
R_θJA	75 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements for sustained power dissipation.

Pinout & Package

1.5KE10-E3/54 is housed in the standard axial-leaded JEDEC Case Style 1.5KE package (DO-201AD), with cathode identified by a color band on the body. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.

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	DO-214AA package (SMB), 1000 W P_PPM, 17.0 V V_C @ 52.3 A, 10.0–11.1 V V_BR	Lower peak power and higher clamping voltage; suited for space-constrained PCBs where 1500 W is not required.	Select SMBJ10A when board area is limited and surge threat level is ≤1 kV/2 Ω (IEC 61000-4-5 Level 3).
1.5SMC10A	SMA package (DO-214AB), 1500 W P_PPM, 17.0 V V_C @ 88.2 A, same V_BR range but higher V_C	Same power rating but 2.5 V higher clamping voltage; less margin for 12 V system ICs with tight V_{ABS MAX}.	Choose 1.5SMC10A only if existing layout uses SMA footprint and clamping margin >17 V is acceptable.

Compared with 1.5KE10-E3/54, SMBJ10A offers smaller size but reduced surge capacity and higher clamping, while 1.5SMC10A matches power rating but sacrifices 2.5 V of clamping headroom - making 1.5KE10-E3/54 optimal for cost-sensitive, high-margin 12 V protection where axial leaded mounting and lowest possible V_C are prioritized.

FAQ

What is the breakdown voltage range for 1.5KE10-E3/54?

The 1.5KE10-E3/54 has a guaranteed breakdown voltage (V_BR) range of 9.5 V to 10.5 V at 1.0 mA test current, per Vishay Document #88301. This tight tolerance ensures consistent clamping onset across production lots and supports reliable design margining for 12 V systems. The 1.5KE10-E3/54's V_BR is validated using JEDEC-standard test conditions and remains stable over its –55 °C to +175 °C operating junction temperature range.

Is 1.5KE10-E3/54 RoHS compliant and halogen-free?

Yes, the 1.5KE10-E3/54 carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per Vishay's material categorization standard (Document #99912). The epoxy molding compound meets UL 94 V-0 flammability rating, and matte tin-plated leads satisfy J-STD-002 solderability requirements. No exemptions apply - the 1.5KE10-E3/54 is certified for unrestricted use in environmentally regulated markets.

What is the maximum clamping voltage of 1.5KE10-E3/54 under surge conditions?

The 1.5KE10-E3/54 clamps to a maximum of 14.5 V at 10 A peak pulse current (I_PPM) with a 10/1000 µs waveform, as specified in Table 1 of Vishay Document #88301. This value represents worst-case device behavior under standardized surge testing and provides critical design margin for protecting 16 V absolute-maximum-rated components. The 1.5KE10-E3/54 achieves this low V_C via low incremental surge resistance and optimized junction geometry.

Can 1.5KE10-E3/54 be used in bidirectional configurations?

No, the 1.5KE10-E3/54 is a unidirectional TVS diode and is not rated for bidirectional operation. Bidirectional variants in the same family use the "CA" suffix (e.g., 1.5KE10CA), which feature symmetrical breakdown in both polarities. Using 1.5KE10-E3/54 in reverse-biased AC applications risks catastrophic failure due to lack of reverse breakdown specification - always verify polarity marking (cathode band) and match device type to circuit topology.

What is the thermal resistance and power derating behavior of 1.5KE10-E3/54?

The 1.5KE10-E3/54 has a typical junction-to-ambient thermal resistance (R_θJA) of 75 °C/W and junction-to-lead resistance (R_θJL) of 15.4 °C/W. Its 6.5 W steady-state power dissipation (P_D) is rated at T_L = 75 °C on an infinite heatsink; derating follows Fig. 5 in Document #88301, reducing to ~3.5 W at 125 °C lead temperature. This behavior directly impacts reliability in enclosed enclosures or high-ambient industrial settings where airflow is limited.
