Product details
Overview
BZT52H-C16,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 16 V nominal breakdown voltage at IZ = 5 mA, 830 mW total power dissipation at Tamb ≤ 25 °C, and 170 Ω maximum differential resistance - used for precision voltage reference and overvoltage clamping in low-power analog supply rails.
For engineers reviewing the BZT52H-C16,115 datasheet, BZT52H-C16,115 pinout, BZT52H-C16,115 application, or BZT52H-C16,115 equivalent, this page delivers verified Zener parameters including VZ, IZSM, rdif, temperature coefficient, and thermal resistance - critical for stable biasing, ESD protection, and regulator feedback loop design.
Technical Context
This Zener operates in reverse-biased breakdown mode with a specified 16 V working voltage (15.3–17.1 V range) at 5 mA test current, exhibiting a +11.2 mV/K temperature coefficient and 75 pF capacitance at 1 MHz/0 V. Its SOD123F package enables surface-mount integration into space-constrained PCBs while maintaining thermal performance via 150 K/W junction-to-solder-point resistance.
Designed for general regulation functions, it supports stable DC bias generation and transient voltage suppression without requiring external bias circuitry - leveraging tight ±5 % tolerance and low 170 Ω dynamic impedance to minimize output drift under load variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 16 V - precise reference voltage at 5 mA Zener test current, enabling accurate voltage regulation in feedback networks. |
| Tolerance | ±5 % - defines 15.3 V to 17.1 V operational window, suitable for non-critical biasing where cost-effective stability is prioritized. |
| Ptot | 830 mW - maximum continuous power dissipation at 25 °C ambient on FR4 PCB with 1 cm² cathode pad, defining safe operating area. |
| rdif | 170 Ω - differential resistance at IZ = 5 mA, indicating voltage regulation sensitivity to current changes in linear applications. |
| SZ | +11.2 mV/K - positive temperature coefficient ensures predictable VZ drift across -65 °C to +150 °C junction range. |
| IZSM | 1.5 A - non-repetitive peak reverse surge current (100 μs pulse), supporting transient overvoltage clamping capability. |
| Cd | 75 pF - junction capacitance at 0 V reverse bias and 1 MHz, limiting high-frequency noise filtering effectiveness above ~20 MHz. |
Pinout & Package
SOD123F surface-mount plastic package: 2-terminal, flat lead, 3.4–3.6 mm length × 2.5–2.7 mm width × 1.0–1.2 mm height; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity-sensitive terminal where reverse breakdown occurs - must be held at higher potential than anode. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path during reverse bias operation. |
Key Features
| Feature | Design Value |
|---|---|
| Three-tolerance series | ±1 %, ±2 %, and ±5 % options enable trade-off between precision and cost - C-series selected here for cost-sensitive regulation. |
| Low-profile SMD package | SOD123F footprint (3.5 × 2.6 mm) allows high-density PCB layout and compatibility with standard reflow soldering processes. |
| High surge capability | 1.5 A non-repetitive peak reverse current supports short-duration transients without degradation - critical for input-stage clamping. |
| Thermal robustness | 150 K/W junction-to-solder-point thermal resistance ensures reliable operation up to 150 °C junction temperature on standard FR4. |
Applications
| Power Supply Reference | Overvoltage Protection |
|---|---|
Use Scenario: Providing stable 16 V reference for op-amp comparator thresholds in industrial sensor signal conditioning circuits. IC Role / Device Role / Timing Role: Zener diode acts as passive voltage reference source, replacing active references where 5 % accuracy suffices. Use Value: Eliminates need for dedicated reference IC, reducing BOM count and board area while maintaining sufficient accuracy for threshold detection. |
Use Scenario: Clamping 24 V DC input rail against surges in programmable logic controller (PLC) digital I/O modules. IC Role / Device Role / Timing Role: Zener functions as shunt overvoltage protector, diverting excess energy to ground when rail exceeds 17.1 V. Use Value: Limits transient-induced damage to downstream logic ICs with 1.5 A surge rating and fast response inherent to PN-junction breakdown. |
| ADC Bias Network | LED Current Regulation |
Use Scenario: Setting mid-rail bias point for single-supply ADC drivers in battery-powered data acquisition systems. IC Role / Device Role / Timing Role: Zener establishes fixed 16 V reference for resistor-divider network generating VREF/2. Use Value: Ensures consistent common-mode voltage despite supply variation, improving ADC linearity and offset stability. |
Use Scenario: Stabilizing forward current for high-brightness white LEDs in automotive interior lighting control units. IC Role / Device Role / Timing Role: Zener regulates current through series resistor by fixing voltage drop across it, compensating for LED VF variance. Use Value: Maintains uniform LED brightness across production batches and temperature ranges using simple two-component solution. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C16-7-F (Diodes Inc.) | Same 16 V nominal, ±5 % tolerance, but 500 mW Ptot and 200 Ω rdif; SOD-123 package (slightly larger footprint). | Limited to lower-power regulation due to reduced power rating; less effective in high-current clamp scenarios. | Select when legacy Diodes Inc. sourcing is required and thermal margin permits lower dissipation. |
| MMBZ5245BS-7-F (Diodes Inc.) | 16 V, ±5 %, but SOT-23 package (3-pin, cathode/anode/common); 350 mW Ptot, 250 Ω rdif. | Requires different footprint and offers no advantage in regulation performance; primarily for dual-Zener configurations. | Avoid unless dual-diode topology is explicitly needed - inferior thermal and impedance specs for single-Zener use. |
Compared with BZT52H-C16,115, the Diodes Inc. BZT52C16-7-F trades 330 mW lower power handling for broader distributor availability, while MMBZ5245BS-7-F introduces unnecessary complexity and reduced performance for basic shunt regulation tasks.

FAQ
What is the maximum continuous reverse current the BZT52H-C16,115 can sustain?
The device does not specify a maximum continuous reverse current; instead, its safe operating limit is defined by power dissipation. At 25 °C ambient, it sustains up to 52 mA (830 mW ÷ 16 V) continuously before exceeding thermal limits - derating required above 25 °C per 150 K/W junction-to-solder-point resistance.
Can BZT52H-C16,115 replace a 1N4744A in existing designs?
No - the 1N4744A is a 14 V, 1 W through-hole Zener in DO-41 package, whereas BZT52H-C16,115 is a 16 V, 830 mW SMD device. Voltage mismatch (14 V vs. 16 V), power difference, and incompatible package prevent direct substitution without circuit revalidation.
How does the +11.2 mV/K temperature coefficient affect long-term stability?
At 16 V nominal, +11.2 mV/K means VZ increases by ~1.8 V over a 150 °C junction temperature swing (−65 °C to +85 °C ambient). This drift must be accommodated in precision references; however, it improves predictability versus negative-coefficient Zeners in warm environments.
Is the SOD123F package compatible with automated optical inspection (AOI)?
Yes - the SOD123F's flat, rectangular body with clear cathode marking bar and standardized 3.5 × 2.6 mm footprint is fully supported by industry-standard AOI systems, enabling reliable solder joint and placement verification in high-volume SMT lines.
