Product details
Overview
BZT52H-C10,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 10 V nominal breakdown voltage at IZ = 5 mA, 830 mW total power dissipation at Tamb ≤ 25 °C, and 70 Ω maximum differential resistance. It serves as a precision voltage reference or shunt regulator in low-power analog signal conditioning and power rail stabilization circuits.
For engineers reviewing the BZT52H-C10,115 datasheet, BZT52H-C10,115 pinout, BZT52H-C10,115 application, or BZT52H-C10,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance to solder point (70 K/W), reverse current at 9 V (≤10 μA), junction temperature limit (150 °C), and SOD123F footprint compatibility with automated reflow assembly.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across its terminals under varying load currents. Its 10 V nominal Zener voltage is specified at 5 mA test current with ±5 % tolerance, and it exhibits a positive temperature coefficient of +4.5 mV/K at IZ = 5 mA.
The device uses planar epitaxial construction for consistent breakdown characteristics and low leakage. With 70 Ω typical differential resistance and ≤10 μA reverse current at 9 V, it delivers tight regulation in low-current bias networks and feedback references for LDOs and op-amps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V at IZ = 5 mA - defines usable regulation range for 10 V reference designs |
| Tolerance | ±5 % - determines worst-case output deviation in voltage reference circuits |
| Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Differential Resistance (rdif) | 70 Ω max - impacts regulation error under load current variation |
| Reverse Current (IR) | ≤10 μA at VR = 9 V - ensures minimal quiescent current in standby-biased references |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - relevant for polarity protection or series diode use cases |
| Junction Temperature (Tj) | 150 °C max - constrains thermal design margin in enclosed or high-ambient environments |
Pinout & Package
SOD123F is a surface-mount plastic package with two leads, 3.4–3.6 mm length, 1.5–1.7 mm width, and 0.55–0.70 mm height. Cathode is marked by a bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-bias current flows anode-to-cathode |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-optimized voltage reference without trimming in non-critical analog monitoring |
| 830 mW power rating | Supports up to ~83 mA regulation current at 10 V, sufficient for IC biasing and sensor excitation |
| 70 K/W thermal resistance (junction-to-solder point) | Allows direct thermal coupling to copper pour for improved power handling in compact layouts |
| SOD123F footprint | Compatible with standard 0805-class pick-and-place and reflow processes; reduces board space vs. DO-35 |
| 150 °C maximum junction temperature | Permits operation in industrial ambient environments up to +105 °C with appropriate derating |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C10-7-F (Diodes Inc.) | Same 10 V ±5 %, SOD-123 package, but 500 mW Ptot and 100 Ω rdif | Lower power handling limits regulation current to ~50 mA; higher impedance increases load regulation error | Select when board-level thermal management is constrained and 50 mA max current suffices |
| MMSZ5240B-TP (Micro Commercial) | 10 V ±5 %, SOD-123, 500 mW Ptot, 17 Ω rdif, but only 125 °C Tj max | Superior dynamic regulation but reduced thermal margin; not rated for >105 °C ambient | Select for high-precision, low-drift biasing where ambient stays below 85 °C |
Compared with BZT52H-C10,115, the Diodes Inc. alternative trades 330 mW power headroom for identical tolerance and package, while the Micro Commercial part improves regulation accuracy at the cost of thermal robustness-making the Nexperia device optimal for industrial environments requiring both power margin and temperature resilience.

FAQ
What is the maximum reverse current at 9 V for BZT52H-C10,115?
The maximum reverse current (IR) is 10 μA at VR = 9 V and Tj = 25 °C, per Table 8 of the official Nexperia datasheet Rev. 7. This value ensures minimal loading on upstream bias sources in reference and reset applications.
Can BZT52H-C10,115 be used in automotive applications?
No. The BZT52H series is explicitly designated as non-automotive qualified per Section 13 of the datasheet. Automotive alternatives must be selected from Nexperia's -Q qualified portfolio, such as the BZT52H-Q series, which undergo AEC-Q200 stress testing.
What is the thermal resistance from junction to solder point?
Rth(j-sp) is 70 K/W, measured with the cathode soldered to a 1 cm² copper pad on single-sided FR4 PCB (Table 6). This value enables accurate thermal modeling when designing for continuous 830 mW operation in confined layouts.
How does the temperature coefficient affect regulation accuracy over temperature?
The temperature coefficient is +4.5 mV/K at IZ = 5 mA, meaning output voltage increases by ~45 mV over a 10 °C rise. For applications requiring <1 % drift from 25 °C to 85 °C, this contributes ~0.27 % error-acceptable in non-precision references but requires compensation in metrology-grade designs.
