BZX784C10-TP Equivalent & Substitute Parts

Part Overview

The BZX784C10-TP is a Zener diode rated at 10 V nominal voltage with 150 mW maximum power dissipation, manufactured by Micro Commercial Co in SOD-723 surface mount packaging. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. The obsolete status requires engineers to evaluate active alternative components that maintain electrical and mechanical compatibility with existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX784C10-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Zener voltage (Vz) must equal 10 V nominal
• Reverse leakage current must not exceed 200 nA @ 7 V
• Forward voltage (Vf) must not exceed 900 mV @ 10 mA
• Impedance (Zzt) must not exceed 20 Ohms
• Operating temperature range must encompass or exceed -55°C to 150°C

Mechanical Compatibility Criteria:

• Surface mount mounting type required
• Package must be compatible with SOD-723 footprint or equivalent small outline diode package
• RoHS3 compliance required
• Moisture sensitivity level must be 1 (Unlimited)

The CMOZ10V TR PBFREE from Central Semiconductor Corp satisfies all substitution criteria while offering enhanced specifications in power rating (300 mW versus 150 mW) and improved tolerance (±5% versus ±6%). The substitute maintains identical zener voltage, reverse leakage, and forward voltage characteristics while providing active product status and extended temperature range capability.

Parameter Comparison

Engineering Selection Recommendations

The CMOZ10V TR PBFREE qualifies as a direct electrical substitute for the BZX784C10-TP based on matched zener voltage, reverse leakage current, forward voltage, and impedance specifications. The substitute component provides superior performance characteristics including higher power dissipation capability (300 mW versus 150 mW), tighter voltage tolerance (±5% versus ±6%), and extended low-temperature operating range (-65°C versus -55°C minimum).

The substitute maintains ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility. Active product status of the CMOZ10V TR PBFREE ensures long-term availability and supply chain continuity compared to the obsolete BZX784C10-TP.

Package transition from SOD-723 to SOD-523 requires PCB layout modification. Both packages are small outline diode formats with comparable footprint dimensions suitable for high-density surface mount applications. Design teams must verify PCB land pattern compatibility and reflow profile suitability for the SOD-523 package before implementation.

Frequently Asked Questions (FAQ)

Q: Can the CMOZ10V TR PBFREE directly replace the BZX784C10-TP without circuit modification?

A: Electrical substitution is valid based on matched zener voltage (10 V), reverse leakage (200 nA @ 7 V), forward voltage (900 mV @ 10 mA), and impedance (20 Ohms maximum). PCB layout modification is required due to package change from SOD-723 to SOD-523. Circuit performance remains equivalent when proper land pattern and reflow parameters are applied.

Q: What are the key differences between the main part and substitute?

A: The CMOZ10V TR PBFREE offers three specification improvements: power rating increased from 150 mW to 300 mW, voltage tolerance tightened from ±6% to ±5%, and operating temperature range extended to -65°C minimum. All critical electrical parameters remain identical. Product status changes from obsolete to active, ensuring future availability.

Q: Are there packaging considerations for the SOD-723 to SOD-523 transition?

A: SOD-523 is a smaller outline diode package compared to SOD-723. PCB footprint dimensions differ, requiring land pattern redesign. Reflow temperature profiles and solder paste application parameters must be verified for the SOD-523 package to ensure reliable solder joint formation and component placement accuracy.

Q: Does the substitute maintain regulatory compliance?

A: Yes. The CMOZ10V TR PBFREE is ROHS3 compliant and carries unlimited moisture sensitivity level (MSL 1), matching the original BZX784C10-TP specifications. Both components meet the same environmental and regulatory requirements.

Q: Why is the substitute rated for higher power dissipation?

A: The CMOZ10V TR PBFREE is rated at 300 mW maximum power versus 150 mW for the BZX784C10-TP. This specification difference reflects the substitute component's enhanced thermal design capability. Circuits designed for 150 mW operation remain fully compatible with the higher-rated substitute.

Q: What is the impact of the ±5% tolerance improvement?

A: The substitute's ±5% zener voltage tolerance is tighter than the original ±6% specification. This provides improved voltage regulation accuracy and reduced circuit performance variation across production batches. Existing circuit designs remain compatible as the tighter tolerance represents a performance enhancement rather than a constraint.
