BZT52C68 Equivalent & Substitute Parts

Part Overview

The BZT52C68 is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, designed for voltage regulation and protection applications. This surface-mount component operates at a nominal Zener voltage of 68 V with a maximum power dissipation of 500 mW in the SOD-123F package. The part is RoHS3 compliant and REACH unaffected, making it suitable for modern electronic assemblies. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the BZT52C68 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Nominal Zener voltage: 68 V
Power dissipation rating: 500 mW
Voltage tolerance: ±5%
Package type: SOD-123F surface mount
Impedance (Max): 240 Ohms
Reverse leakage current: 45 nA @ 47.6 V
Forward voltage: 1 V @ 10 mA
Operating temperature range: -65°C to 150°C
RoHS3 compliance status
REACH unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The BZT52C68 RHG variant from Taiwan Semiconductor Corporation satisfies all specified parameters and is therefore a valid substitute.

Engineering Selection Recommendations

Both the BZT52C68 and BZT52C68 RHG are active-status components manufactured by Taiwan Semiconductor Corporation with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences.

The BZT52C68 RHG variant includes specified Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating superior moisture handling characteristics during storage and assembly processes. Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance in target applications.

For applications requiring high-reliability voltage regulation at 68 V with 500 mW power dissipation in surface-mount form factor, either part number provides equivalent performance within the specified operating temperature range of -65°C to 150°C.
