Product details
Overview
BZT52H-B16,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, rated for 16 V nominal breakdown voltage at IZ = 5 mA, with 830 mW total power dissipation and 170 Ω maximum differential resistance. It serves as a precision voltage reference or shunt regulator in low-power analog supply rails and overvoltage protection circuits.
For engineers reviewing the BZT52H-B16,115 datasheet, BZT52H-B16,115 pinout, BZT52H-B16,115 application, or BZT52H-B16,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), thermal resistance (150 K/W junction-to-solder-point), reverse current limit (≤1 μA at VR = 12.8 V), and SOD123F footprint compatibility with automated SMT assembly.
Technical Context
This device operates in reverse-biased Zener breakdown mode to maintain stable voltage across its terminals under varying load or input conditions. Its 16 V nominal regulation point is specified at 5 mA test current, with temperature coefficient of +11.2 mV/K and typical reverse leakage <1 μA below 12.8 V.
The SOD123F package enables surface-mount integration with low thermal resistance (150 K/W to solder point) and supports pulsed non-repetitive surge currents up to 1.5 A (100 μs). It is not automotive-qualified and is intended for industrial, consumer, and computing applications requiring stable, low-cost voltage clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.7 V to 16.3 V at IZ = 5 mA - defines precise regulation threshold for feedback or clamp circuits |
| Tolerance | ±2 % - ensures tight voltage control without post-production trimming |
| Differential Resistance (rdiff) | ≤170 Ω - limits output impedance drift under load variation |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling |
| Reverse Current (IR) | ≤1 μA at VR = 12.8 V - guarantees low quiescent leakage in standby or high-impedance nodes |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low conduction loss when used in forward-biased ESD paths |
| Junction Temperature (Tj) | −65 °C to +150 °C - supports operation in extended industrial ambient environments |
Pinout & Package
SOD123F is a 2-pin surface-mount plastic package with cathode-marked flat lead geometry; dimensions are 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), with 0.7 mm lead pitch and 1.2 mm cathode pad area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse current during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes bias path for reverse conduction |
Key Features
| Feature | Design Value |
|---|---|
| Three tolerance options | ±1 %, ±2 %, and ≈±5 % - enables cost/performance trade-off across design tiers |
| Wide voltage range | 2.4 V to 75 V (E24 series) - covers most standard logic supply and interface voltage references |
| Low thermal resistance | 150 K/W junction-to-solder-point - improves power derating margin on standard FR4 PCBs |
| Pulse surge capability | 1.5 A non-repetitive peak reverse current (100 μs) - provides transient overvoltage resilience |
| Surface-mount optimized | SOD123F footprint compatible with reflow soldering only - ensures manufacturability in high-volume SMT lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C16-7-F | ±5 % tolerance, 200 Ω rdiff, same SOD123 package | Lower precision; suitable where cost outweighs voltage stability | Select for non-critical biasing where ±0.8 V variation is acceptable |
| MMSZ5245B-7-F | ±5 % tolerance, SOD-123 package, 16 V nominal, 100 Ω rdiff | Higher differential conductance; tighter thermal specs (Tj = 150 °C) | Prefer for higher-current shunt applications needing lower dynamic impedance |
Compared with BZT52H-B16,115, BZT52C16-7-F trades precision for cost in non-critical clamping, while MMSZ5245B-7-F offers better dynamic regulation but lacks the ±2 % tolerance needed for precision reference designs.

FAQ
What is the maximum continuous reverse current for BZT52H-B16,115 at 25 °C ambient?
The device is rated for 830 mW total power dissipation at Tamb ≤ 25 °C. At 16 V Zener voltage, this corresponds to a maximum continuous reverse current of 51.9 mA (830 mW ÷ 16 V), assuming no additional thermal derating. Actual usable current depends on PCB copper area and ambient conditions.
Can BZT52H-B16,115 be used in automotive applications?
No. Per Nexperia's revision history (Rev. 7, Jan 2023), the BZT52H series is explicitly designated as non-automotive qualified. It lacks AEC-Q200 stress testing and automotive-grade process controls. For automotive use, consult Nexperia's -Q qualified alternatives such as PZTA42-Q or BZX84-Q series.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At +11.2 mV/K, the Zener voltage increases by approximately 1.8 V across a 160 K temperature span (−40 °C to +125 °C). This results in a total shift from ~14.2 V to ~17.8 V - a ±11 % deviation. Designs requiring stable regulation across this range must include compensation or operate within narrower thermal bands.
Is the SOD123F package compatible with standard reflow profiles?
Yes. The datasheet specifies reflow soldering as the only recommended method. The SOD123F outline complies with JEDEC MS-012, supporting peak temperatures up to 260 °C for ≤10 seconds. Thermal resistance data assumes tin-plated FR4 with single-sided 1 cm² cathode pad, matching IPC-A-610 Class 2/3 requirements.
