Engineering Selection Recommendations

BZV85-C33,133 (Parametric Equivalent): The BZV85-C33,133 manufactured by NXP USA Inc. is a parametric equivalent to the BZV85-C33,113. Both parts share identical electrical specifications: 33 V nominal zener voltage, ±5% tolerance, 1 W maximum power, 45 Ohms maximum impedance, and 50 nA reverse leakage current at 23 V. Both operate to 200°C maximum temperature and are housed in DO-41 through-hole axial packages. The primary difference is packaging format: BZV85-C33,113 is supplied in Cut Tape, while BZV85-C33,133 is supplied in Bulk. This part is a direct functional replacement with no circuit modification required. RoHS compliance status is not specified for this variant.

1N5937BRLG (Similar Part): The 1N5937BRLG manufactured by onsemi is a similar part with matching 33 V nominal zener voltage and ±5% tolerance. This part differs in power rating (3 W versus 1 W), impedance (33 Ohms versus 45 Ohms), reverse leakage current (1 µA @ 25.1 V versus 50 nA @ 23 V), and forward voltage (1.5 V @ 200 mA versus 1 V @ 50 mA). The 1N5937BRLG operates across an extended temperature range of -65°C to 200°C and is RoHS3 compliant. This part is suitable for applications requiring higher power dissipation capability or lower impedance characteristics. Circuit validation is required to confirm compatibility with the original design.

2EZ33D5 (Similar Part): The 2EZ33D5 manufactured by Microchip Technology is a similar part with matching 33 V nominal zener voltage and ±5% tolerance. This part differs in power rating (2 W versus 1 W), impedance (23 Ohms versus 45 Ohms), reverse leakage current (500 nA @ 25.1 V versus 50 nA @ 23 V), forward voltage (1.2 V @ 200 mA versus 1 V @ 50 mA), and maximum operating temperature (150°C versus 200°C). The 2EZ33D5 is RoHS non-compliant. This part is suitable for applications requiring higher power dissipation or lower impedance. The reduced maximum operating temperature and RoHS non-compliance status must be evaluated against design requirements. Circuit validation is required.

Frequently Asked Questions (FAQ)

Q: Can BZV85-C33,133 be used as a direct replacement for BZV85-C33,113?

A: Yes. The BZV85-C33,133 is a parametric equivalent with identical electrical specifications and through-hole DO-41 package configuration. No circuit modification is required. The only difference is the packaging format (Bulk versus Cut Tape).

Q: What is the primary difference between the main part and the similar parts?

A: The main part BZV85-C33,113 is rated at 1 W maximum power dissipation. The similar parts 1N5937BRLG (3 W) and 2EZ33D5 (2 W) have higher power ratings. All three maintain the same 33 V nominal zener voltage and ±5% tolerance. Higher power-rated parts have lower impedance and higher reverse leakage current characteristics.

Q: Can 1N5937BRLG or 2EZ33D5 be used in place of BZV85-C33,113?

A: Both parts share the same 33 V nominal zener voltage and ±5% tolerance, making them functionally compatible for voltage regulation. However, they differ in power dissipation capability, impedance, leakage current, and forward voltage characteristics. Circuit validation is required to confirm suitability for the specific application. The higher power ratings of these parts allow operation in higher current or higher dissipation environments.

Q: What are the compliance differences between these parts?

A: BZV85-C33,113 and 1N5937BRLG are both RoHS3 compliant. The 2EZ33D5 is RoHS non-compliant. If RoHS compliance is a design requirement, 2EZ33D5 is not suitable. All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: How do impedance differences affect circuit performance?

A: Impedance (Zzt) affects the dynamic response of the zener diode during transient conditions. The main part BZV85-C33,113 has 45 Ohms maximum impedance. The 1N5937BRLG has 33 Ohms, and the 2EZ33D5 has 23 Ohms. Lower impedance provides faster voltage regulation response but may increase noise sensitivity. Circuit validation is required to confirm impedance compatibility.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current affects power consumption and circuit stability when the zener diode is reverse-biased. The main part has 50 nA @ 23 V. The 1N5937BRLG has 1 µA @ 25.1 V (20 times higher), and the 2EZ33D5 has 500 nA @ 25.1 V (10 times higher). Higher leakage current increases standby power consumption and may affect precision voltage reference applications.

Q: Are all parts available in the same package format?

A: All parts are available in DO-204AL, DO-41, or Axial package designations. However, the main part BZV85-C33,113 is supplied in Cut Tape packaging, BZV85-C33,133 in Bulk, 1N5937BRLG in Cut Tape, and 2EZ33D5 in Cut Tape. Packaging format does not affect electrical performance or physical compatibility.

Q: What is the operating temperature range for each part?

A: BZV85-C33,113 and BZV85-C33,133 operate to 200°C maximum. The 1N5937BRLG operates from -65°C to 200°C (extended range). The 2EZ33D5 operates from -65°C to 150°C (reduced maximum). If the application requires operation above 150°C, the 2EZ33D5 is not suitable.
