Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX84B13-7-F is permissible when the replacement component maintains the following critical electrical parameters: nominal zener voltage of 13 V, maximum impedance of 30 Ohms, reverse leakage current of 100 nA at 8 V, and forward voltage of 900 mV at 10 mA. The package type must remain SOT-23-3 to ensure mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Variations in power rating (300 mW or higher), zener voltage tolerance (±2% or ±5%), and operating temperature range (-65°C to 150°C or -55°C to 150°C) are permissible provided the application requirements do not mandate the original specifications. All substitute parts must maintain RoHS3 compliance and surface-mount configuration.

Engineering Selection Recommendations

The BZX84C13-TP manufactured by Micro Commercial Co qualifies as a direct substitute for the BZX84B13-7-F based on electrical parameter alignment and compliance certifications. Both components are active-status products with RoHS3 compliance, REACH unaffected status, and identical package configurations.

Selection between the main part and substitute should be based on application-specific requirements:

• BZX84B13-7-F is appropriate when the tighter ±2% zener voltage tolerance and extended low-temperature operating range (-65°C minimum) are mandatory design requirements.

• BZX84C13-TP is appropriate when the increased 350 mW power rating provides design margin for higher dissipation scenarios, and the ±5% tolerance and -55°C minimum operating temperature are acceptable within application specifications.

Both components maintain identical impedance, reverse leakage, and forward voltage characteristics, ensuring equivalent performance in voltage regulation and protection circuits.

Frequently Asked Questions (FAQ)

Q: Can BZX84C13-TP replace BZX84B13-7-F in all applications?

A: Substitution is valid when the application tolerates ±5% zener voltage tolerance (versus ±2%) and operates within the -55°C to 150°C temperature range. If the design requires -65°C minimum temperature operation or ±2% tolerance, the original BZX84B13-7-F must be used.

Q: What is the significance of the power rating difference (300 mW vs. 350 mW)?

A: The BZX84C13-TP 350 mW rating provides 50 mW additional dissipation capacity. This allows operation at higher zener currents without exceeding thermal limits. Applications with lower power requirements operate identically with either rating.

Q: Are the packages physically identical?

A: Both components use the SOT-23-3 package designation (also referenced as TO-236-3 or SC-59). Physical dimensions, lead spacing, and PCB footprints are identical, permitting direct board-level substitution without layout modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both BZX84B13-7-F and BZX84C13-TP are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8541.10.0050).

Q: What electrical parameters must remain identical for substitution?

A: Nominal zener voltage (13 V), maximum impedance (30 Ohms), reverse leakage current (100 nA @ 8 V), and forward voltage (900 mV @ 10 mA) must be maintained. These parameters define functional equivalence in voltage regulation circuits.

Q: Is moisture sensitivity a consideration for storage or handling?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component storage and handling practices apply without special precautions.
