Engineering Selection Recommendations
Parametric Equivalents (Direct Substitution):
BZT52B30S R9G and BZT52C30S R9G are parametric equivalents manufactured by Taiwan Semiconductor Corporation. Both maintain identical electrical specifications to the main part with the exception of voltage tolerance (±2% versus ±5%). These parts are suitable for direct substitution where packaging format differs (Tape & Reel or Cut Tape & Digi-Reel) but electrical performance remains equivalent. Both are RoHS3 Compliant and Active status.
Direct Manufacturer Equivalent:
MM3Z30VC from Fairchild Semiconductor meets all primary equivalence criteria with 30 V nominal Zener voltage, 200 mW power rating, and SOD-323F package. Impedance is specified at 75 Ohms, which is within acceptable tolerance. RoHS3 compliance status is not specified in available documentation.
Similar Alternatives:
MM3Z30VB from onsemi provides improved voltage tolerance (±2%) and is RoHS3 Compliant. Impedance specification of 75 Ohms is acceptable. This part is suitable where tighter tolerance is required.
UDZSTE-1730B from Rohm Semiconductor maintains the 30 V, 200 mW specification but exhibits higher impedance (200 Ohms) and reverse leakage current (100 nA @ 23 V). Operating temperature minimum is -55°C, which is 10°C higher than the main part. This part is suitable only where these parameter variations are acceptable to the application.
All substitute parts listed are Active status and RoHS3 Compliant where specified.
Frequently Asked Questions (FAQ)
Q: Can BZT52B30S R9G replace BZT52C30S RRG directly?
A: Yes. Both parts share identical electrical specifications (30 V, 200 mW, SOD-323F package, -65°C to 150°C operating range). The difference is voltage tolerance (±2% versus ±5%) and packaging format. BZT52B30S R9G offers tighter tolerance and is supplied in Tape & Reel format.
Q: What is the difference between BZT52C30S R9G and BZT52C30S RRG?
A: Both parts are identical in electrical specification. The difference is packaging format: R9G is supplied in Cut Tape & Digi-Reel format, while RRG packaging format is not specified. Both are manufactured by Taiwan Semiconductor Corporation and are RoHS3 Compliant.
Q: Can MM3Z30VC from Fairchild Semiconductor be used as a substitute?
A: Yes. MM3Z30VC meets all primary equivalence criteria: 30 V nominal Zener voltage, 200 mW power dissipation, SOD-323F package, and -65°C to 150°C operating temperature. Impedance is 75 Ohms, which is within acceptable range. Verify RoHS3 compliance requirements for your application.
Q: Is UDZSTE-1730B a suitable substitute?
A: UDZSTE-1730B maintains 30 V and 200 mW specifications in SOD-323F package. However, it exhibits higher impedance (200 Ohms versus 80 Ohms), higher reverse leakage current (100 nA @ 23 V versus 45 nA @ 21 V), and a minimum operating temperature of -55°C instead of -65°C. Use this part only where these parameter variations are acceptable.
Q: What packaging formats are available for 30 V, 200 mW Zener diodes?
A: The substitute parts listed are available in the following formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel, and Bulk. All maintain the SOD-323F package type. Select packaging format based on assembly process requirements and inventory management.
Q: Are all substitute parts RoHS3 Compliant?
A: BZT52B30S R9G, BZT52C30S R9G, MM3Z30VB, and UDZSTE-1730B are confirmed RoHS3 Compliant. MM3Z30VC RoHS3 compliance status is not specified in available documentation. Verify compliance requirements for your application before selection.
Q: What is the significance of voltage tolerance (±2% versus ±5%)?
A: Voltage tolerance defines the acceptable deviation of the Zener voltage from the nominal 30 V specification. ±2% tolerance (±0.6 V) is tighter than ±5% tolerance (±1.5 V). Select tighter tolerance where circuit design requires precise voltage regulation. Looser tolerance is acceptable for general-purpose applications.
Q: Can these parts be used interchangeably in high-temperature applications?
A: All substitute parts except UDZSTE-1730B support the full -65°C to 150°C operating range. UDZSTE-1730B operates from -55°C to 150°C. For applications requiring operation below -55°C, use BZT52C30S RRG, BZT52B30S R9G, BZT52C30S R9G, MM3Z30VC, or MM3Z30VB.
