Product details
Overview
BZT52H-B10,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, rated for 10 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 70 Ω maximum differential resistance - used for precision voltage reference and overvoltage protection in low-power DC rails.
For engineers reviewing the BZT52H-B10,115 datasheet, BZT52H-B10,115 pinout, BZT52H-B10,115 application, or BZT52H-B10,115 equivalent, this page delivers verified Zener parameters, thermal performance under PCB-mount conditions, cathode/anode terminal mapping, and direct-fit alternatives for 10 V regulation in space-constrained designs.
Technical Context
This Zener operates in reverse-bias breakdown mode with tightly controlled 10.0 V ±2 % tolerance at IZ = 5 mA, exhibiting low 70 Ω dynamic impedance and temperature coefficient of +4.5 mV/K - enabling stable reference generation across -65 °C to +150 °C ambient range.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it delivers 830 mW total power dissipation when mounted with 1 cm² cathode pad, and supports non-repetitive surge currents up to 3.0 A (100 μs pulse) without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 9.80 V to 10.20 V at IZ = 5 mA - ensures tight 10 V regulation for feedback loops and reference circuits |
| Tolerance | ±2 % - enables accurate voltage clamping without post-production trimming |
| Differential Resistance rdif | ≤ 70 Ω - minimizes output voltage shift under load current variation |
| Total Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C with 1 cm² cathode pad - supports continuous operation in compact layouts |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - allows reliable anode-cathode polarity verification during test |
| Reverse Current IR | ≤ 10 μA at VR = 7.6 V - guarantees low leakage in standby-mode protection circuits |
| Thermal Resistance Rth(j-sp) | 70 K/W - defines junction-to-solder-point thermal path for thermal design margining |
Pinout & Package
SOD123F plastic surface-mount package: 2.5–2.7 mm length, 1.0–1.2 mm width, 0.55–0.70 mm height; flat lead profile optimized for reflow soldering on standard FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked side with bar; connects to regulated output node or voltage reference point |
| 2 | Anode (A) | Ground or lower-potential rail connection; reverse-biased during Zener operation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C10,115 | ±5 % tolerance, higher 100 Ω rdif, same SOD123F package | Acceptable where 10 V ±5 % suffices and cost is prioritized over regulation precision | Select for cost-sensitive consumer electronics where tighter tolerance is unnecessary |
| MMSZ5240B-7-F | ±5 % tolerance, 150 Ω rdif, SOD-123 package (identical mechanical outline) | Limited to 500 mW Ptot; requires derating above 75 °C ambient | Choose only if existing BOM uses Diodes Inc. parts and thermal margin exceeds 100 °C |
Compared with BZT52H-B10,115, the BZT52C10,115 trades regulation accuracy for lower unit cost, while MMSZ5240B-7-F offers second-source availability but sacrifices 40 % power handling and thermal robustness - making the Nexperia part optimal for precision, high-reliability 10 V reference tasks.

FAQ
What is the maximum continuous reverse current this Zener can handle at 10 V?
The BZT52H-B10,115 is not rated for continuous reverse current at breakdown voltage; its safe operating limit is defined by power dissipation. At 10 V, maximum continuous Zener current is 83 mA (830 mW ÷ 10 V), assuming full thermal derating is applied per the datasheet's ambient temperature curve.
Can this diode be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing variations in VZ and rdif, causing current imbalance when paralleled. Even matched units risk thermal runaway due to positive temperature coefficient above ~5 V. Use a single higher-power device or active regulation instead.
Is the SOD123F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method for SOD123F. The package supports JEDEC J-STD-020D-compliant peak temperatures up to 260 °C, with thermal resistance data validated using standard FR4 PCB mounting conditions described in the datasheet.
How does the ±2 % tolerance affect circuit accuracy in a 10 V reference design?
At 10 V nominal, ±2 % tolerance means actual VZ falls between 9.80 V and 10.20 V at 5 mA. This introduces a ±200 mV absolute error in open-circuit reference voltage, which must be accounted for in downstream comparator thresholds or ADC reference scaling - no additional calibration is required if system tolerances accommodate this band.
