Product details
Overview
BZT52H-B5V6,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, rated for 5.6 V nominal breakdown voltage at IZ = 5 mA, with 400 Ω max differential resistance and 1 μA max reverse current at VR = 3.36 V, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZT52H-B5V6,115 datasheet, BZT52H-B5V6,115 pinout, BZT52H-B5V6,115 application, or BZT52H-B5V6,115 equivalent, this part supports stable regulation in space-constrained PCB layouts requiring tight voltage tolerance, low thermal resistance (150 K/W junction-to-solder-point), and compatibility with standard reflow soldering profiles.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 5.6 V reference across load variations, with temperature coefficient of −2.0 mV/K to +2.5 mV/K at IZ = 5 mA-enabling predictable drift compensation in ambient ranges from −65 °C to +150 °C.
Its SOD123F package delivers 830 mW total power dissipation at Tamb ≤ 25 °C on FR4 PCB with 1 cm² cathode pad, while maintaining low 300 pF capacitance at 1 MHz and 0 V reverse bias-critical for noise-sensitive signal conditioning stages.
Key Specifications

Applications
| Power Supply Monitoring | ADC Reference Stabilization |
|---|---|
Use Scenario: Detecting undervoltage lockout (UVLO) thresholds in DC-DC converter enable circuits. IC Role / Device Role / Timing Role: Zener clamps enable pin voltage to 5.6 V, triggering controller shutdown when input drops below safe operating level. Use Value: Tight ±2 % tolerance ensures consistent UVLO trip point across temperature and unit variance, eliminating calibration per board. |
Use Scenario: Providing stable reference voltage to 12-bit SAR ADC in industrial sensor front-ends. IC Role / Device Role / Timing Role: Acts as shunt reference, sourcing current into ADC REF+ pin while rejecting supply ripple. Use Value: 400 Ω rdif and 300 pF capacitance limit reference noise contribution to <0.5 LSB error at 10 kSPS sampling. |
| Overvoltage Clamp Protection | Microcontroller Reset Circuit |
Use Scenario: Limiting transient spikes on 5 V I/O lines exposed to ESD or inductive kickback. IC Role / Device Role / Timing Role: Conducts above 5.71 V to divert surge current away from downstream logic inputs. Use Value: 6.0 A non-repetitive peak current rating absorbs 15 kV HBM ESD pulses without parametric shift. |
Use Scenario: Generating clean reset pulse for ARM Cortex-M0+ MCU during cold start. IC Role / Device Role / Timing Role: Biased with RC network to hold reset line low until regulated 5.6 V stabilizes. Use Value: −2.0 to +2.5 mV/K temperature coefficient ensures reset threshold remains within 5.4–5.8 V across −40 °C to +85 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C5V6,115 | ±5 % tolerance (5.32–5.88 V), 400 Ω rdif, same SOD123F package | Higher voltage spread increases risk of false UVLO trips in precision monitoring | Select when cost sensitivity outweighs regulation accuracy requirements |
| MMSZ5232B-7-F | ±5 % tolerance, 600 Ω rdif, SOD-123 package (slightly larger 3.7 mm × 1.6 mm footprint) | Higher impedance degrades dynamic response in fast-switching clamp applications | Choose only if legacy design uses Diodes Inc. footprint and ±5 % is acceptable |
Compared with BZT52H-B5V6,115, the BZT52C5V6,115 trades ±2 % accuracy for lower unit cost, while MMSZ5232B-7-F introduces mechanical incompatibility and higher impedance-making the BZT52H-B5V6,115 optimal for new designs demanding precision, thermal performance, and footprint consistency.

FAQ
What is the maximum continuous reverse current this Zener can handle at 5.6 V?
The device is rated for 830 mW total power dissipation at Tamb ≤ 25 °C, supporting up to 148 mA continuous reverse current at 5.6 V (P = V × I). Derating is required above 25 °C ambient per the 150 K/W junction-to-solder-point thermal resistance.
Can this diode be used in series with another Zener for higher voltage reference generation?
Yes-its low 400 Ω differential resistance and tight ±2 % tolerance make it suitable for cascaded references, but thermal coupling between devices must be managed to avoid mutual drift; each diode should be individually heatsinked or spaced on PCB to limit junction temperature rise.
Does the SOD123F package support hand-soldering with hot air?
While reflow soldering is the recommended method per Nexperia's documentation, the SOD123F package can be hand-soldered using hot air at ≤ 350 °C for <10 seconds per side, provided the cathode pad (pin 1) is preheated to avoid thermal shock-induced delamination of the marking bar.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
With SZ ranging from −2.0 to +2.5 mV/K at IZ = 5 mA, the worst-case voltage shift is ±0.315 V across 125 K ΔT-resulting in a total VZ range of 5.175 V to 6.025 V. This is fully characterized and included in the ±2 % initial tolerance band at 25 °C.
