Product details
Overview
BZV49-C16,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT89 package, designed for precision DC voltage reference and stabilization in power supply rails. It delivers a nominal 16 V regulation at 5 mA test current, with ±5% tolerance, 10–40 Ω differential resistance, and −50 μA reverse leakage at 12.8 V, supporting stable operation up to 150 °C junction temperature.
For engineers reviewing the BZV49-C16,115 datasheet, BZV49-C16,115 pinout, BZV49-C16,115 application, or BZV49-C16,115 equivalent, this device is selected for low-noise analog references, overvoltage clamping in industrial sensor interfaces, and feedback path regulation in isolated DC-DC converters where thermal stability and repeatable breakdown behavior are critical.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a specified 15.3–17.1 V working voltage range at 5 mA test current. Its temperature coefficient of +10.4 to +14.0 mV/K enables predictable drift compensation in temperature-sensitive circuits, while its 1 W total power dissipation rating requires thermal management via the exposed collector pad in the SOT89 package.
The device exhibits non-repetitive peak reverse power dissipation up to 40 W for 100 μs pulses, supporting transient surge suppression in input protection stages. Its 75 pF capacitance at 0 V reverse bias and low leakage (≤0.05 μA at VR = 12.8 V) ensure minimal signal loading in high-impedance reference nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 15.3 V to 17.1 V at IZtest = 5 mA - defines stable regulation window under nominal bias |
| Differential Resistance (rdif) | 10 Ω to 40 Ω - determines output impedance and load regulation error sensitivity |
| Temp. Coefficient (SZ) | +10.4 to +14.0 mV/K - quantifies voltage drift per degree Celsius for thermal design margining |
| Reverse Leakage (IR) | ≤0.05 μA at VR = 12.8 V - ensures minimal current draw in standby or high-Z reference paths |
| Total Power Dissipation (Ptot) | 1 W at Tamb = 25 °C on ceramic substrate - sets maximum continuous DC power handling with heatsinking |
| Junction Temperature (Tj) | −65 °C to +150 °C - defines operational envelope for automotive and industrial ambient conditions |
Pinout & Package

FAQ
What is the maximum continuous reverse power this diode can handle?
The BZV49-C16,115 has a total power dissipation limit of 1 W at 25 °C ambient on a 2.5 cm² ceramic substrate. Derating is required above 25 °C per its 125 K/W junction-to-ambient thermal resistance - e.g., only ~0.5 W is permissible at 75 °C ambient.
Does this Zener diode require a series current-limiting resistor?
Yes - a series resistor must be used to set the operating current within the 1–10 mA range for optimal regulation and temperature stability. At 5 mA test current, the diode achieves its specified 15.3–17.1 V VZ and minimum differential resistance.
How does the SOT89 package improve thermal performance vs. SOD-123?
The SOT89's exposed collector pad (Pin 3) reduces thermal resistance from junction to tie-point to 15 K/W - nearly 4× better than typical SOD-123 packages (~55 K/W). This allows higher continuous power handling and improved long-term parametric stability under thermal cycling.
Can BZV49-C16,115 replace BZX84-C16 in SOT23 footprint designs?
No - BZV49-C16,115 uses SOT89 (3-lead, wider pitch, thermal pad), while BZX84-C16 uses SOT23 (3-lead, smaller pitch, no thermal pad). The packages are mechanically incompatible, and BZV49 offers higher power (1 W vs. 350 mW) and different thermal characteristics.
