Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5225BS-7-F (Diodes Inc.) | Same SOD-123 package; 4.7 V ±5%, but 350 mW rating and 100 Ω ZZT | Lower power handling limits use in sustained 5 mA bias; higher impedance affects regulation accuracy | Select when footprint compatibility is critical and thermal margin allows reduced PD |
| 1SMA5914BT3G (onsemi) | SMA package (larger); 4.7 V ±5%, 1.5 W rating, 10 Ω ZZT, but requires PCB area increase | Superior thermal performance and lower impedance suit high-stability references, not space-constrained layouts | Choose for demanding analog references where SOD-123F size constraint is relaxed |
Compared with MMBZ5225BS-7-F and 1SMA5914BT3G, the BZT52C4V7 RHG delivers optimal balance of SOD-123F footprint, 500 mW capability, and 80 Ω impedance-making it ideal for space-limited, medium-precision voltage reference designs.

What is the zener voltage tolerance of BZT52C4V7 RHG?
The BZT52C4V7 RHG has a nominal zener voltage of 4.7 V with a tolerance of ±5%, resulting in a guaranteed range of 4.47 V to 4.94 V when tested at 5 mA. This tolerance is confirmed in the Electrical Specifications table of the official Taiwan Semiconductor datasheet (Version G1804), and applies specifically to the BZT52C4V7 RHG variant-not inferred from adjacent part numbers.
What package type does BZT52C4V7 RHG use?
The BZT52C4V7 RHG uses the SOD-123F surface-mount package, as explicitly stated in the Ordering Information section and Mechanical Data table of the Taiwan Semiconductor datasheet. Dimensions are 3.3–3.9 mm in length, 1.5–1.7 mm in width, and 0.5–0.7 mm in height, with matte tin-plated terminals compliant with J-STD-002 solderability standards.
What is the maximum power dissipation for BZT52C4V7 RHG?
The BZT52C4V7 RHG is rated for 500 mW maximum power dissipation at 25 °C ambient temperature, as specified in both the KEY PARAMETERS and ABSOLUTE MAXIMUM RATINGS tables. Derating is required above 25 °C, with a junction-to-ambient thermal resistance of 350 °C/W defining the linear derating slope.
Is BZT52C4V7 RHG RoHS and halogen-free compliant?
Yes, the BZT52C4V7 RHG complies with RoHS Directive 2011/65/EU and WEEE 2002/96/EC, and is halogen-free per IEC 61249-2-21. This compliance is explicitly declared in the FEATURES section of the Taiwan Semiconductor datasheet and verified through material declarations for the SOD-123F molding compound and plating.
What is the leakage current specification for BZT52C4V7 RHG?
The BZT52C4V7 RHG exhibits a maximum leakage current of 2.7 µA at a reverse voltage (VR) of 2.0 V, as documented in the ELECTRICAL SPECIFICATIONS table. This value is measured under standard test conditions (TA = 25 °C) and reflects the device's ability to minimize standby current in high-impedance bias networks.
