SMCJ160C Transient Voltage Suppressor - Equivalent & Substitute Parts

Part Overview

The SMCJ160C is a 1500W bidirectional transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This surface mount component operates at a reverse standoff voltage of 160V with a maximum clamping voltage of 287V and peak pulse current of 5.4A. The device is designed for general-purpose transient voltage suppression applications and is currently in active production status. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the DO-214AB (SMC) package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCJ160C is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Reverse standoff voltage must be 160V (Typ)
• Breakdown voltage minimum must be 178V or greater
• Peak pulse power rating must be 1500W or greater
• Peak pulse current must support 5.4A or greater at 10/1000µs pulse width
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Requirements:

• Package format must be DO-214AB (SMC) surface mount
• Bidirectional channel configuration must be 1 channel
• Mounting type must be surface mount

Regulatory Compliance:

• RoHS3 compliance status
• REACH compliance status
• ECCN and HTSUS classifications

The SMCJ160CA qualifies as a direct substitute based on matching all critical electrical parameters within the specified tolerances and identical mechanical packaging.

Engineering Selection Recommendations

SMCJ160C (Taiwan Semiconductor Corporation)

Primary selection when Taiwan Semiconductor sourcing is required. Active production status with 799 units in current inventory. Packaged in Tape & Reel format suitable for automated assembly operations. RoHS3 compliant and REACH unaffected. ECCN classification EAR99 applies.

SMCJ160CA (Fairchild Semiconductor)

Qualified substitute when alternative sourcing is necessary. Active production status with 23,100 units in current inventory. Supplied in Bulk packaging format. Electrical parameters demonstrate improved peak pulse current capability (5.8A versus 5.4A) and lower clamping voltage (259V versus 287V), both favorable for transient suppression performance. RoHS3 compliant and REACH unaffected. ECCN classification EAR99 applies.

Both parts meet identical regulatory compliance requirements and operate within the same temperature range. Selection between these parts is based on supply chain availability, packaging requirements, and inventory status.

Frequently Asked Questions (FAQ)

Q: Can SMCJ160CA be used as a direct replacement for SMCJ160C in existing designs?

A: Yes. Both parts share identical reverse standoff voltage (160V), breakdown voltage (178V minimum), peak pulse power (1500W), operating temperature range (-55°C to 150°C), and package format (DO-214AB SMC). The SMCJ160CA exhibits lower clamping voltage (259V versus 287V) and higher peak pulse current (5.8A versus 5.4A), both of which are compatible with applications designed for the SMCJ160C.

Q: What is the significance of the clamping voltage difference between these parts?

A: Clamping voltage represents the maximum voltage across the TVS diode during transient suppression. The SMCJ160CA's lower clamping voltage (259V) provides improved transient suppression performance compared to the SMCJ160C (287V). This is a favorable characteristic for circuit protection.

Q: Are there packaging differences between SMCJ160C and SMCJ160CA?

A: Both parts use identical DO-214AB (SMC) surface mount packages. The primary packaging difference is supply format: SMCJ160C is supplied in Tape & Reel format, while SMCJ160CA is supplied in Bulk format. This distinction affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Reverse standoff voltage of 160V, (2) Breakdown voltage minimum of 178V, (3) Peak pulse power of 1500W or greater, (4) Peak pulse current capability of 5.4A or greater, (5) Operating temperature range of -55°C to 150°C, and (6) DO-214AB (SMC) surface mount package format with single bidirectional channel configuration.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both SMCJ160C and SMCJ160CA are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080.

Q: What inventory considerations should influence part selection?

A: SMCJ160C has 799 units in current stock, while SMCJ160CA has 23,100 units available. For applications requiring immediate delivery or high-volume procurement, SMCJ160CA availability may provide supply chain advantages.
