Part Overview

The BZT52C24-13 is a Zener diode rated at 24 V nominal voltage with 500 mW power dissipation in SOD-123 surface mount packaging, manufactured by Diodes Incorporated. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement. The device operates across a temperature range of -65°C to 150°C with ±6% voltage tolerance and is classified as RoHS non-compliant. Equivalent alternatives are available from multiple manufacturers with improved compliance status and active product availability.

Substitute Part Grouping Explanation

Substitution of the BZT52C24-13 is determined by the following critical parameters: nominal Zener voltage of 24 V, maximum power dissipation of 500 mW, SOD-123 surface mount package, and operating temperature range. Parts are grouped into three categories based on substitution relationship:

Parametric Equivalents maintain identical electrical specifications (24 V, 500 mW, ±6% tolerance) and differ only in packaging format (Tape & Reel versus Cut Tape) or product status. These parts are direct functional replacements.

Upgrade Equivalents maintain the 24 V Zener voltage and SOD-123 package but feature reduced power ratings (200 mW) or improved tolerance specifications (±5% or ±2%). These parts are suitable for applications where lower power dissipation is acceptable.

Manufacturer Recommended Alternatives include parts from different manufacturers that meet or exceed the original specifications while offering improved compliance certifications, lower impedance, or automotive-grade qualifications. These parts provide enhanced reliability and regulatory compliance.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents): BZT52C24-13-F and BZT52C24-7-F are direct electrical equivalents to the BZT52C24-13, maintaining identical 24 V nominal voltage, ±6% tolerance, and 500 mW power rating. Both parts are ROHS3 compliant and carry active product status. Selection between these two depends on packaging requirements: BZT52C24-13-F is supplied in Tape & Reel format, while BZT52C24-7-F is available in Cut Tape & Digi-Reel format. These parts are recommended for applications requiring no design modification.

Compliance-Enhanced Alternatives: MMSZ5252BT1G (onsemi), MMSZ5252C-G3-08 (Vishay), MMSZ5252ET1G (onsemi), SZMMSZ5252ET1G (onsemi), and SZMMSZ5252ET3G (onsemi) all maintain the 24 V Zener voltage and 500 mW power rating while offering improved impedance characteristics (33 Ohms versus 70 Ohms) and tighter tolerance specifications (±5% or ±2%). All are ROHS3 compliant with active product status. SZMMSZ5252ET1G and SZMMSZ5252ET3G carry automotive-grade qualification (AEC-Q101) and are suitable for automotive applications.

Lower Power Alternative: BZT52C24-TP (Micro Commercial Co) provides a 24 V Zener diode with reduced power dissipation (200 mW) in SOD-123 packaging. This part is suitable for applications where the original 500 mW specification exceeds circuit requirements.

Non-Recommended: MMSZ4714-TP features a 33 V Zener voltage and is not suitable as a direct substitute for the 24 V BZT52C24-13 due to voltage mismatch. CMHZ4709 TR PBFREE, while offering 24 V and 500 mW specifications, exhibits different forward voltage characteristics (1.5 V @ 100 mA versus 900 mV @ 10 mA) and is not recommended for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can BZT52C24-13-F be used as a direct replacement for BZT52C24-13?

A: Yes. BZT52C24-13-F is a parametric equivalent with identical electrical specifications (24 V, ±6%, 500 mW, SOD-123). The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Discontinued). No circuit modification is required.

Q: What is the difference between BZT52C24-13-F and BZT52C24-7-F?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging: BZT52C24-13-F is supplied in Tape & Reel format, while BZT52C24-7-F is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly line requirements.

Q: Can MMSZ5252BT1G replace BZT52C24-13?

A: Yes, with design considerations. MMSZ5252BT1G maintains the 24 V Zener voltage and 500 mW power rating but features improved impedance (33 Ohms versus 70 Ohms) and tighter tolerance (±5% versus ±6%). The lower impedance may affect circuit behavior in applications sensitive to dynamic impedance characteristics. Electrical verification is necessary for critical applications.

Q: What is the advantage of MMSZ5252C-G3-08 over the original BZT52C24-13?

A: MMSZ5252C-G3-08 offers tighter voltage tolerance (±2% versus ±6%), lower impedance (33 Ohms versus 70 Ohms), and ROHS3 compliance. These improvements provide enhanced voltage regulation accuracy and reduced temperature coefficient effects. The part is suitable for precision voltage reference applications.

Q: Are SZMMSZ5252ET1G and SZMMSZ5252ET3G suitable for automotive applications?

A: Yes. Both parts carry automotive-grade qualification (AEC-Q101) and are designated for automotive use. They maintain 24 V nominal voltage, 500 mW power rating, and SOD-123 packaging with improved impedance (33 Ohms) and ±5% tolerance. These parts are recommended for automotive circuit designs.

Q: Why is MMSZ4714-TP listed as a manufacturer recommendation if it has 33 V instead of 24 V?

A: MMSZ4714-TP is included in the substitute list but is not recommended for direct replacement due to voltage mismatch. It is listed as a manufacturer alternative for applications where 33 V Zener voltage is acceptable or where circuit topology permits voltage adjustment.

Q: Can BZT52C24-TP be used in place of BZT52C24-13?

A: BZT52C24-TP is suitable only for applications where the 500 mW power specification is not required. This part features reduced power dissipation (200 mW) while maintaining 24 V Zener voltage and SOD-123 packaging. Circuit analysis is necessary to confirm that 200 mW power rating is sufficient for the intended application.

Q: What packaging options are available for 24 V, 500 mW Zener diodes in SOD-123?

A: Multiple packaging formats are available: Tape & Reel (BZT52C24-13-F, CMHZ4709 TR PBFREE, MMSZ5252ET1G, SZMMSZ5252ET1G, SZMMSZ5252ET3G, MMSZ5252C-G3-08) and Cut Tape & Digi-Reel (BZT52C24-7-F, MMSZ5252BT1G). Selection depends on assembly equipment and procurement volume requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant. The original BZT52C24-13 is RoHS non-compliant. Compliance-enhanced alternatives are available from multiple manufacturers for applications requiring regulatory adherence.
