Product details
Overview
BZV55-B10,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, designed for precision voltage reference and regulation in low-current analog circuits. It delivers a nominal 10 V ±2 % Zener voltage at 5 mA, with 50 Ω typical differential resistance, 4.5 mV/K temperature coefficient, and 90 pF junction capacitance at 1 MHz - enabling stable biasing in sensor interfaces and power supply feedback loops.
For engineers reviewing the BZV55-B10,115 datasheet, BZV55-B10,115 pinout, BZV55-B10,115 application, or BZV55-B10,115 equivalent, key selection criteria include Zener tolerance (±2 %), thermal resistance (300 K/W to solder point), non-repetitive surge capability (3.0 A peak reverse current), and SOD80C footprint compatibility with reflow-soldered PCBs.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining a stable 9.8–10.2 V output across 1–20 mA reverse bias currents. Its low 50 Ω differential resistance ensures minimal voltage drift under load variation, while its negative temperature coefficient (−2.0 to −4.5 mV/K) supports predictable thermal behavior in ambient ranges up to +150 °C.
The SOD80C package provides hermetic glass sealing for long-term stability and moisture resistance, with thermal performance characterized by Rth(j-sp) = 300 K/W to solder point and Rth(j-a) = 380 K/W in free air - critical for thermal design in space-constrained consumer and industrial modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.8 V to 10.2 V at IZ = 5 mA - defines tight regulation window for reference-grade applications |
| Differential Resistance (rdif) | 50 Ω typical at IZ = 5 mA - ensures <100 mV output shift over ±5 mA current change |
| Temperature Coefficient (SZ) | −2.0 to −4.5 mV/K - enables predictable voltage drift compensation in temperature-varying circuits |
| Junction Capacitance (Cd) | 90 pF at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in filtering and timing paths |
| Non-repetitive Peak Reverse Current (IZSM) | 3.0 A for tp = 100 μs - supports transient overvoltage clamping without failure |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - confirms low-loss forward conduction for polarity protection use cases |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height; cathode marked by band; optimized for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased during Zener operation; marking band identifies this terminal |
| 2 | Anode | Connected to circuit ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener tolerance (B-series) | Enables precise voltage references without post-production trimming in production-grade analog designs |
| Low 50 Ω differential resistance | Minimizes output voltage variation under dynamic load changes in feedback networks and sensor excitation |
| Hermetic glass SOD80C package | Guarantees long-term parameter stability and humidity immunity in unsealed consumer and industrial enclosures |
| 300 K/W junction-to-solder-point thermal resistance | Supports reliable thermal transfer to copper pour or thermal pad, enabling >400 mW operation with board-level heatsinking |
| 90 pF junction capacitance | Permits use in low-noise reference buffers and RC timing circuits without significant signal phase distortion |
Applications
| Industrial Sensor Signal Conditioning | Low-Power Microcontroller Reset Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C10,113 | ±5 % tolerance, higher 120 Ω rdif, same SOD80C package | Acceptable where cost-sensitive designs tolerate wider voltage spread and higher output impedance | Select when ±5 % regulation accuracy suffices and lower unit cost is prioritized over reference-grade stability |
| MMSZ5240B-7-F | ±5 % tolerance, 17 Ω rdif, SOD-123 package (larger footprint, higher thermal mass) | Better regulation stability under varying current but requires PCB layout revision for larger pad spacing | Choose when lower dynamic impedance is critical and board space permits SOD-123 rework |
Compared with BZV55-B10,115, BZX55C10,113 trades tighter tolerance and lower rdif for lower cost, while MMSZ5240B-7-F improves dynamic regulation at the expense of package compatibility and cost - making BZV55-B10,115 optimal for space-constrained, precision-referenced SMD designs requiring hermetic reliability.

FAQ
What is the maximum continuous reverse current for BZV55-B10,115 at 25 °C ambient?
The device supports up to 250 mA forward current, but for Zener operation, the recommended continuous reverse current is ≤20 mA to maintain 10 V regulation within ±2 % and avoid exceeding 400 mW total power dissipation at Tamb ≤ 50 °C. At higher ambient temperatures, derating is required per the thermal resistance specification.
Does BZV55-B10,115 meet RoHS and REACH compliance standards?
Yes - BZV55-B10,115 is manufactured by Nexperia in full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free packaging confirmed in the official product data sheet Rev. 5 (2011) and subsequent compliance declarations.
Can BZV55-B10,115 be used in place of a 1N4740A in existing designs?
No - although both are 10 V Zeners, BZV55-B10,115 uses a SOD80C package (3.5 mm × 1.5 mm) versus the 1N4740A's DO-41 (5.2 mm × 2.7 mm) through-hole package, and has different thermal characteristics (Rth(j-sp) = 300 K/W vs. ~100 K/W for DO-41). Direct substitution requires PCB redesign and thermal validation.
What is the typical reverse leakage current at 7 V for BZV55-B10,115?
At VR = 7 V and Tj = 25 °C, the reverse leakage current is ≤200 nA - specified in Table 7 of the datasheet for the BZV55-B10 variant. This ultra-low leakage supports high-impedance bias networks and battery-critical standby circuits.
