SMLJ110CA Equivalent & Substitute Parts

Part Overview

The SMLJ110CA is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional zener diode features a 110V reverse standoff voltage with a 177V maximum clamping voltage and 16.8A peak pulse current capability. The component is housed in a DO-214AB (SMC) package and is RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified sources meeting identical or compatible electrical and mechanical specifications.

• Current - Peak Pulse and Power - Peak Pulse may vary
• Operating Temperature Range remains -55°C to 150°C

Parameter Comparison

Engineering Selection Recommendations

SMDJ110CA (Alpha & Omega Semiconductor Inc.) is the primary direct substitute, offering equivalent electrical performance with 17A peak pulse current and 3000W power dissipation. This part maintains full RoHS3 compliance and identical voltage specifications. Current inventory of 30,200 units supports immediate availability.

5.0SMDJ110CA (MDE Semiconductor Inc) is suitable for applications requiring enhanced transient energy absorption, with 28.3A peak pulse current and 5000W power dissipation. This part is appropriate when circuit design permits higher current handling or when additional margin against transient events is required. RoHS3 compliance is maintained.

SMCJ110CA (Fairchild Semiconductor) is applicable in applications with lower transient current requirements, featuring 8.4A peak pulse current and 1500W power dissipation. This part is suitable for circuits where the transient energy is limited and lower power dissipation is acceptable. RoHS3 compliance status is not specified in available documentation.

All substitute parts share identical voltage specifications (110V reverse standoff, 122V breakdown minimum, 177V clamping maximum) and package configuration (DO-214AB, SMC), ensuring mechanical and thermal compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can SMDJ110CA directly replace SMLJ110CA in production?

A: Yes. SMDJ110CA maintains identical voltage specifications (110V reverse standoff, 122V breakdown, 177V clamping) and package configuration (DO-214AB, SMC). Peak pulse current is 17A versus 16.8A, representing a negligible difference within normal component tolerances. Both parts are RoHS3 compliant.

Q: What is the difference between SMLJ110CA and 5.0SMDJ110CA?

A: Both parts share identical voltage ratings and package type. The primary difference is transient energy handling: 5.0SMDJ110CA provides 28.3A peak pulse current and 5000W power dissipation compared to SMLJ110CA's 16.8A and 3000W. The 5.0SMDJ110CA is suitable for circuits experiencing higher transient stress.

Q: Is SMCJ110CA compatible with SMLJ110CA?

A: SMCJ110CA is mechanically and thermally compatible, sharing the DO-214AB (SMC) package and identical voltage specifications. However, it provides only 8.4A peak pulse current and 1500W power dissipation. This part is suitable only for applications with lower transient current requirements.

Q: Are all substitute parts RoHS3 compliant?

A: SMLJ110CA, SMDJ110CA, and 5.0SMDJ110CA are confirmed RoHS3 compliant. SMCJ110CA RoHS3 compliance status is not specified in available documentation.

Q: Do all parts operate within the same temperature range?

A: Yes. All listed parts operate from -55°C to 150°C junction temperature, ensuring thermal compatibility across the specified operating range.

Q: What packaging format is used for all parts?

A: All parts use DO-214AB (SMC) surface-mount package, ensuring identical PCB footprint and reflow soldering compatibility.
