Product details
Overview
BZV55C10 from Taiwan Semiconductor is a surface-mount Zener diode with nominal zener voltage 10 V, ±5% tolerance, 500 mW power dissipation, and 5 mA test current, used for precision low-voltage stabilization in DC/DC converters and adapter circuits.
For engineers reviewing the BZV55C10 datasheet, BZV55C10 pinout, BZV55C10 application, or BZV55C10 equivalent, key selection criteria include zener voltage accuracy (9.4–10.6 V), dynamic impedance (15 Ω at 5 mA), leakage current (0.1 µA at 7.5 V), and MMELF package thermal performance (RθJA = 300 °C/W).
Technical Context
The BZV55C10 operates as a reverse-biased voltage reference with tightly controlled breakdown characteristics. Its zener voltage is specified at 5 mA test current (IZT), with differential impedance of 15 Ω and knee impedance of 70 Ω at 1 mA (IZK), ensuring stable regulation under varying load conditions.
Designed for ambient operation up to +125 °C with junction temperature rating of −65 to +175 °C, it features hermetically sealed glass construction, matte tin-plated leads compliant with J-STD-002, and cathode band polarity marking - all supporting reliable long-term performance in compact power management layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ @ IZT | 9.4–10.6 V (±5% tolerance at 5 mA; defines stable reference window) |
| IZT | 5 mA (standard test current for zener voltage specification) |
| Zzt @ IZT | 15 Ω (low dynamic impedance ensures minimal output voltage variation with load changes) |
| PD | 500 mW (maximum continuous power dissipation at TA = 25 °C) |
| IR @ VR | 0.1 µA at 7.5 V (ultra-low reverse leakage preserves accuracy in high-impedance bias networks) |
| TJ max | +175 °C (enables use in thermally demanding industrial environments) |
| RθJA | 300 °C/W (thermal resistance informs PCB copper area requirements for thermal management) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240B | Same 10 V nominal, SOD-123 package, 350 mW rating, 17 Ω Zzt, 0.1 µA leakage | Lower power rating and higher thermal resistance limit use in sustained high-current regulation | Preferred for space-constrained PCBs where 350 mW suffices and SOD-123 footprint is standardized |
| 1N4740A | 10 V nominal, DO-41 through-hole, 1 W rating, 20 Ω Zzt, 5 µA leakage | Larger size, higher leakage, and through-hole mounting incompatible with fully SMT designs | Suitable for prototyping or legacy through-hole assemblies requiring higher power margin |

FAQ
What is the zener voltage tolerance of the BZV55C10?
The BZV55C10 has a nominal zener voltage of 10 V with a standard tolerance of ±5%, meaning its actual breakdown voltage falls between 9.4 V and 10.6 V when tested at 5 mA (IZT) under pulse conditions. This tolerance is confirmed in the Electrical Specifications table and applies across the full operating temperature range.
What package type does the BZV55C10 use?
The BZV55C10 uses the MMELF (Miniature Metal Electrode Leadless Face) package, a glass-encapsulated cylindrical surface-mount outline conforming to JEDEC DO-213AA, Variation AA. Its dimensions are 3.50 ± 0.20 mm in length and Ø1.50 ± 0.10 mm in diameter, with cathode polarity indicated by a visible band.
What is the maximum power dissipation for the BZV55C10?
The BZV55C10 has a maximum power dissipation (PD) of 500 mW at ambient temperature (TA = 25 °C). Derating is required above 25 °C, following the Power Dissipation vs. Ambient Temperature curve in the datasheet - for example, ~300 mW at TA = 75 °C.
How does the BZV55C10 perform in terms of leakage current?
The BZV55C10 exhibits a maximum reverse leakage current (IR) of 0.1 µA at VR = 7.5 V, measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and precision reference applications where current draw must be minimized - a key differentiator versus higher-leakage alternatives like 1N4740A.
Is the BZV55C10 RoHS compliant and lead-free solder compatible?
Yes, the BZV55C10 is RoHS compliant and features matte tin-plated leads qualified per J-STD-002 for solderability. It supports standard lead-free reflow profiles (peak temperature ≤ 260 °C) and is supplied in 13" tape-and-reel packaging (10,000 units per reel) under ordering codes BZV55C10 L0 or BZV55C10 L0G.
