Product details
Overview
BZV55-B16,115 from Nexperia is a ±2 % tolerance silicon Zener diode in SOD80C glass SMD package, rated for 15.7 V to 16.3 V nominal Zener voltage at 5 mA, with 50 Ω typical differential resistance and 10.4 mV/K temperature coefficient. It delivers low-power voltage regulation in space-constrained analog power rails, such as sensor biasing and reference stabilization in industrial control modules.
For engineers reviewing the BZV55-B16,115 datasheet, BZV55-B16,115 pinout, BZV55-B16,115 application, or BZV55-B16,115 equivalent, this page provides verified Zener voltage, thermal resistance, reverse current limits, differential resistance, and SOD80C footprint details required for precision low-voltage regulation design and BOM validation.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and temperature conditions. Its 50 Ω typical differential resistance ensures minimal output voltage drift across 1–5 mA operating current, while its 10.4 mV/K temperature coefficient enables predictable thermal compensation in non-temperature-compensated circuits.
The device uses hermetically sealed glass construction for long-term stability and moisture resistance, and is rated for 400 mW total power dissipation at ≤50 °C ambient - critical for thermally isolated PCB layouts in compact instrumentation designs.
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 point for 16 V nominal rail stabilization |
| Differential Resistance (rdif) | 50 Ω typical at IZ = 5 mA - determines output impedance and load regulation error (e.g., ±50 mV per ±1 mA current change) |
| Temperature Coefficient (SZ) | 10.4 mV/K typical - quantifies voltage drift per degree Celsius, enabling thermal error budgeting in unheated enclosures |
| Reverse Current (IR) | <50 nA at VR = 11.2 V - ensures negligible leakage in high-impedance reference nodes |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - sets maximum continuous power handling on standard FR-4 without heatsinking |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - calculates junction temperature rise (e.g., +152 °C rise at 400 mW), informing derating requirements |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs pulse - supports transient overvoltage clamping in ESD-protected signal conditioning stages |
Pinout & Package
Hermetically sealed glass SOD80C surface-mount package: 3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height; cathode indicated by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation current |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tight regulation without post-production trimming in cost-sensitive consumer and industrial power supplies |
| Low 50 Ω differential resistance | Reduces output voltage variation under dynamic load changes, improving accuracy in ADC reference buffers |
| SOD80C glass SMD package | Provides hermetic sealing against humidity-induced parameter shift, supporting 15+ year field reliability in outdoor sensors |
| 400 mW power rating at 50 °C | Allows direct integration into 0805-class footprints without thermal vias in low-power IoT node power domains |
| 10.4 mV/K temperature coefficient | Supports predictable thermal drift modeling for calibration routines in handheld test equipment |
Applications
| Industrial Sensor Biasing | ADC Reference Stabilization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C16,113 | ±5 % tolerance (15.2–16.8 V), 100 Ω rdif, same SOD80C package | Higher voltage spread and poorer load regulation; suitable only for non-critical biasing | Select when cost priority outweighs regulation accuracy and thermal stability |
| MMSZ5245B-TP | ±5 % tolerance, 17 Ω rdif, SOD-123 package, 500 mW rating | Lower rdif improves regulation but larger package increases board area; different thermal profile | Choose for improved load regulation where PCB space allows SOD-123 footprint |
Compared with BZV55-B16,115, BZX55C16,113 trades voltage precision for lower unit cost, while MMSZ5245B-TP offers better regulation performance at the expense of package compatibility and thermal resistance - making BZV55-B16,115 optimal for space-constrained, accuracy-critical 16 V reference designs.

FAQ
What is the guaranteed Zener voltage range for BZV55-B16,115 at 5 mA?
The guaranteed Zener voltage is 15.7 V minimum to 16.3 V maximum at test current IZ = 5 mA, per Table 8 of the official Nexperia datasheet Rev. 5. This ±2 % tolerance is maintained across the full operating temperature range of −65 °C to +200 °C junction temperature.
Can BZV55-B16,115 be used in place of a 16 V Zener with tighter thermal drift requirements?
No - its 10.4 mV/K temperature coefficient is fixed and not compensated. For lower drift, consider temperature-compensated Zeners like the BZX85C16 or series-connected Zener-thermistor networks. This part is intended for applications where drift is modeled and calibrated out in firmware or hardware.
What is the maximum continuous forward current rating for BZV55-B16,115?
The absolute maximum forward current is 250 mA per Table 5 (Limiting Values). However, forward conduction is not a functional operating mode; the device is designed for reverse-bias Zener operation only. Forward voltage is specified as ≤0.9 V at 10 mA for polarity verification.
Does the SOD80C package support reflow soldering per JEDEC J-STD-020?
Yes - Nexperia specifies reflow compatibility for SOD80C in Figure 7 of the datasheet, with peak temperature up to 260 °C for ≤10 seconds. The glass body withstands standard lead-free reflow profiles, and the recommended footprint matches IPC-7351B medium density for reliable solder joint formation.
