Product details
Overview
BZT52H-C24,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 24 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 220 Ω maximum differential resistance - used for precision voltage reference and overvoltage clamping in low-power DC rails.
For engineers reviewing the BZT52H-C24,115 datasheet, BZT52H-C24,115 pinout, BZT52H-C24,115 application, or BZT52H-C24,115 equivalent, this part supports stable regulation in space-constrained consumer and industrial PCBs where thermal resistance to solder point (150 K/W) and non-repetitive surge capability (1.25 A @ 100 μs) are design-critical.
Technical Context
This Zener operates in reverse-biased breakdown mode with a temperature coefficient of +16.8 mV/K at IZ = 5 mA, enabling predictable drift compensation in mid-voltage references. Its 22.8 V to 25.6 V working voltage range (±5 %) and 30 μA reverse current at VR = 19.2 V support robust noise immunity in feedback loops.
The device uses planar epitaxial construction for stable rdif and low capacitance (22 pF @ 1 MHz, VR = 0 V), making it suitable for high-frequency decoupling and transient suppression without signal distortion in analog sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 24 V nominal at IZ = 5 mA; actual range 22.8 V–25.6 V defines usable regulation window for 24 V rail monitoring |
| Tolerance | ±5 % (C-series); sets worst-case output deviation in voltage-reference circuits without trimming |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C on FR4 PCB with 1 cm² cathode pad; determines max continuous Zener current (≈34.6 mA) |
| Differential Resistance (rdif) | 220 Ω max at IZ = 5 mA; limits regulation error under load step changes in low-current bias networks |
| Reverse Current (IR) | 30 μA max at VR = 19.2 V (80 % VZ); ensures minimal leakage-induced offset in high-impedance divider nodes |
| Thermal Resistance (Rth(j-sp)) | 150 K/W junction-to-solder-point; enables accurate thermal modeling when mounted per SOD123F reflow footprint |
| Non-repetitive Peak Current (IZSM) | 1.25 A for 100 μs pulses; provides ESD/inductive-spike clamping headroom in I/O protection stages |
Pinout & Package
SOD123F surface-mount plastic package: 2.5–2.7 mm length, 1.0–1.2 mm width, 0.55–0.70 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity mark aligns with PCB silkscreen bar for automated optical inspection |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-bias path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Power rating | 830 mW at 25 °C ambient enables use in 24 V/30 mA regulator shunt without heatsinking |
| Voltage tolerance | ±5 % (C-series) allows direct replacement in cost-sensitive designs without recalibration |
| Package size | SOD123F footprint (3.4 × 1.7 mm) supports high-density layout in wearables and IoT edge nodes |
| Surge capability | 1.25 A non-repetitive peak current handles IEC 61000-4-5 Level 3 surges without derating |
| Thermal performance | 150 K/W Rth(j-sp) permits accurate junction temperature estimation using solder-point thermocouple measurement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C24-7-F (Diodes Inc.) | Same 24 V ±5 %, SOD-123 package, but 500 mW Ptot and 250 Ω rdif | Lower power rating reduces margin in sustained 25 mA shunt loads; higher rdif increases regulation error | Select only if thermal budget is constrained and surge immunity is secondary |
| MMSZ5245B-TP (Micro Commercial) | 24 V ±5 %, SOD-123, 500 mW Ptot, 30 μA IR at 19.2 V, but no published IZSM spec | Lacks documented surge rating; unsuitable for I/O protection requiring 1.25 A transient handling | Prefer for static reference use only - avoid in clamping or surge-prone locations |
Compared with BZT52H-C24,115, the Diodes Inc. and Micro Commercial alternatives offer identical voltage grading but trade off 40 % lower power dissipation and missing surge validation - making them viable only in low-stress reference roles, not in robust clamping or rail supervision.

FAQ
What is the maximum continuous Zener current for BZT52H-C24,115 at 70 °C ambient?
At 70 °C ambient, derated power dissipation is 570 mW (per linear derating from 830 mW at 25 °C). With VZ ≈ 24 V, max continuous current is 23.8 mA. This assumes FR4 PCB mounting with 1 cm² cathode pad and no forced airflow.
Does BZT52H-C24,115 meet automotive qualification standards?
No. Per Nexperia's Rev. 7 datasheet (January 2023), BZT52H-C24,115 is explicitly non-automotive qualified. Automotive-grade alternatives (e.g., BZT52H-Q series) require separate ordering and are tested to AEC-Q200 standards.
How does the 16.8 mV/K temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
Over that range, ΔT = 165 K yields ±2.77 V drift (16.8 mV/K × 165 K). Combined with ±5 % initial tolerance (±1.2 V), total worst-case VZ spread is 24 V ±3.97 V - critical for applications requiring tighter than ±10 % regulation.
Can BZT52H-C24,115 be used in parallel for higher power handling?
No. Zener diodes exhibit negative temperature coefficient mismatch; paralleling causes current hogging and thermal runaway. For >830 mW, use a single higher-rated device (e.g., BZX84-C24) or active regulation instead.
