Product details
Overview
BZT52H-C5V6,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 5.6 V nominal breakdown voltage at IZ = 5 mA, with 400 Ω maximum differential resistance and 1 μA reverse current at VR = 4.0 V, used for precision voltage reference and overvoltage protection in low-power analog supply rails.
For engineers reviewing the BZT52H-C5V6,115 datasheet, BZT52H-C5V6,115 pinout, BZT52H-C5V6,115 application, or BZT52H-C5V6,115 equivalent, this page delivers verified Zener parameters, thermal resistance (Rth(j-sp) = 70 K/W), junction temperature limit (150 °C), and SOD123F footprint compatibility for PCB layout validation and replacement selection.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage across its terminals under varying load currents. Its ±5 % tolerance and -2.0 to +2.5 mV/K temperature coefficient enable predictable regulation in ambient-temperature-stable circuits.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it supports pulsed reverse power up to 40 W (tp = 100 μs) and continuous dissipation of 830 mW at Tamb ≤ 25 °C with cathode pad area of 1 cm².
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 5.2 V to 6.0 V at IZ = 5 mA - defines usable regulation window for 5.6 V nominal rail |
| Differential Resistance (rdif) | ≤ 400 Ω - limits output voltage deviation under load current changes |
| Reverse Current (IR) | ≤ 1 μA at VR = 4.0 V - ensures minimal leakage in standby or undervoltage lockout circuits |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - enables use as polarity-sensitive clamp or series diode in low-drop paths |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 board |
| Junction Temperature (Tj) | 150 °C maximum - constrains thermal design margin when operating near Ptot limit |
| Thermal Resistance (Rth(j-sp)) | 70 K/W - quantifies temperature rise from junction to cathode solder point, critical for thermal relief pad sizing |
Pinout & Package
SOD123F plastic surface-mount package: 2-terminal, flat lead, 3.4–3.6 mm length × 2.5–2.7 mm width × 0.7–0.9 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; reverse-bias configuration enables Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % voltage tolerance | Enables cost-effective regulation where tight accuracy is not required, e.g., non-critical biasing |
| 830 mW total power rating | Supports higher-current Zener shunt applications than standard 500 mW SOD-123 devices |
| SOD123F package footprint | Matches industry-standard reflow land pattern (2.8 × 1.6 mm occupied area), ensuring drop-in manufacturability |
| 150 °C max junction temperature | Allows operation in high-ambient environments such as enclosed industrial controllers without derating below 85 °C |
| 70 K/W junction-to-solder-point Rth | Enables accurate thermal modeling when cathode pad is connected to internal copper pour for heat spreading |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Providing stable 5.6 V reference for ADC voltage dividers or op-amp bias networks in battery-powered sensor nodes. IC Role / Device Role / Timing Role: Zener diode acting as two-terminal shunt voltage reference, absorbing excess current to hold node voltage constant. Use Value: Delivers <1 % regulation error over 1–10 mA load range due to low rdif and defined VZ tolerance. |
Use Scenario: Protecting microcontroller I/O pins from ESD-induced transients exceeding 5.6 V in USB peripheral interfaces. IC Role / Device Role / Timing Role: Reverse-biased clamping device that conducts above VZ, diverting surge current away from sensitive inputs.

| Low-Power Bias Generator | Comparator Threshold Set |
Use Scenario: Generating fixed 5.6 V bias for JFET amplifier stages in audio preamplifier front-ends. IC Role / Device Role / Timing Role: Passive voltage source establishing DC operating point independent of supply variation. Use Value: Maintains bias stability within ±0.3 V over -40 °C to +85 °C due to compensated temperature coefficient (-2.0 to +2.5 mV/K). |
Use Scenario: Setting precise trip point for window comparators monitoring 5 V system rails in industrial PLC modules. IC Role / Device Role / Timing Role: Precision voltage reference defining upper threshold in dual-comparator fault detection circuit. Use Value: Enables ±0.2 V threshold accuracy at room temperature, leveraging 5.6 V nominal VZ and ±5 % tolerance band. |
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 | Same SOD123F package and 5.6 V nominal VZ, but ±5 % tolerance (identical); differs only in marking code and minor process revision | No functional difference; identical electrical specs and thermal performance per Rev. 7 datasheet | Select when legacy BOM specifies BZT52C5V6,115 - fully interchangeable with no design change required |
| MMSZ5232BS-7-F | 5.6 V Zener, ±5 %, SOD-123 package, but 500 mW Ptot, 600 Ω rdif, and higher Rth(j-a) (330 K/W) | Lower power handling and poorer regulation stability limit use to sub-5 mA loads and low-thermal-conductivity boards | Choose only if BZT52H-C5V6,115 is unavailable and application operates below 300 mW with adequate thermal margin |
Compared with BZT52H-C5V6,115, the BZT52C5V6,115 offers identical regulation performance and thermal behavior, while the MMSZ5232BS-7-F trades 330 mW lower power rating and 200 Ω higher impedance for broader distributor availability-making the Nexperia part preferred for thermally constrained or higher-current shunt designs.

FAQ
What is the maximum continuous reverse current this Zener can handle at 5.6 V?
The BZT52H-C5V6,115 is not rated for continuous reverse current at exact VZ; instead, its safe operating current is determined by power dissipation. At 5.6 V, maximum continuous IZ = 830 mW / 5.6 V ≈ 148 mA - but derating is required above 25 °C ambient per Rth(j-a) = 330 K/W. Full 148 mA is only valid with active cooling or reduced ambient.
Can this diode be used in series with another Zener to achieve higher reference voltage?
Yes - stacking multiple BZT52H-C5V6,115 diodes in series yields additive breakdown voltages (e.g., two in series ≈ 11.2 V), provided each shares current equally via balancing resistors. However, temperature coefficients compound, increasing overall drift; for >10 V references, dedicated high-voltage Zeners are more stable.
Does the SOD123F package support automated optical inspection (AOI) after reflow?
Yes - the SOD123F package has a standardized silhouette and cathode bar marking visible under standard AOI lighting. The 0.25 mm lead thickness and 0.55 mm pitch allow reliable solder joint inspection, and the flat top surface enables consistent contrast-based fiducial detection during board-level verification.
How does the -2.0 to +2.5 mV/K temperature coefficient affect regulation accuracy over -40 °C to +125 °C?
Across that range, ΔT = 165 K, so worst-case VZ shift = 165 K × 2.5 mV/K = 413 mV. With nominal VZ = 5.6 V, this represents ±7.4 % drift - meaning actual regulation falls between 5.19 V and 6.01 V. For tighter stability, use temperature-compensated references or add external compensation networks.
