Product details
Overview
BZV55-C10,115 from Nexperia is a ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 10 V nominal Zener voltage at 5 mA, with 50 Ω typical differential resistance and 4.5 mV/K temperature coefficient. It delivers stable voltage regulation in low-power analog reference and overvoltage protection circuits, supporting industrial sensor signal conditioning and microcontroller I/O rail clamping.
For engineers reviewing the BZV55-C10,115 datasheet, BZV55-C10,115 pinout, BZV55-C10,115 application, or BZV55-C10,115 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge (40 W, 100 µs), reverse leakage at 7 V (200 nA), and direct comparison to functional alternatives including BZX55-C10 and MMBZ5240B.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its 10 V nominal Zener voltage is specified at IZ = 5 mA, with a temperature coefficient of +4.5 mV/K - indicating predictable positive drift with junction temperature rise.
The device uses a planar epitaxial construction with low parasitic capacitance (90 pF at 1 MHz, 0 V) and exhibits non-repetitive peak reverse power dissipation of 40 W for 100 µs square-wave pulses, enabling robust transient suppression in DC bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V at IZ = 5 mA - defines usable regulation window for precision 10 V references |
| Differential Resistance (rdiff) | 50 Ω typical at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +4.5 mV/K - quantifies voltage drift per degree Celsius rise in junction temperature |
| Reverse Leakage (IR) | 200 nA at VR = 7 V - ensures minimal quiescent current in high-impedance bias networks |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs - supports short-duration surge suppression without failure |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard PCB layout |
| Junction-to-Ambient Rth | 380 K/W in free air - informs thermal derating requirements for ambient temperature operation |
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.

Applications
| Industrial Sensor Reference | Microcontroller I/O Clamping |
|---|---|
Use Scenario: Providing stable 10 V reference for 12-bit ADC biasing in temperature transmitters. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, sourcing current to maintain fixed node voltage independent of supply ripple. Use Value: Enables <±0.5 % full-scale accuracy over 0–70 °C due to known +4.5 mV/K drift and low 50 Ω rdiff. | Use Scenario: Protecting GPIO pins of STM32F4xx against 12 V accidental overvoltage events. IC Role / Device Role / Timing Role: Shunt clamp limiting input voltage to 10.6 V maximum, diverting excess current to ground before damage threshold.

| Power Supply Feedback Divider | Low-Power Analog Biasing |
Use Scenario: Setting feedback voltage in isolated flyback converter using TL431 secondary-side controller. IC Role / Device Role / Timing Role: Provides precise 10 V reference to calibrate optocoupler LED current, stabilizing output regulation. Use Value: Maintains ±1 % output voltage accuracy across line/load variations due to tight 9.4–10.6 V tolerance and low tempco. | Use Scenario: Establishing bias point for op-amp input stage in battery-powered gas detector. IC Role / Device Role / Timing Role: Supplies low-noise, low-drift reference voltage to amplifier common-mode node. Use Value: Draws only 200 nA leakage at 7 V, extending 10-year battery life while maintaining 10 V stability within ±0.1 %. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C10 | Same 10 V nominal, ±5 % tolerance, but TO-92 through-hole package; higher Rth(j-a) (500 K/W) | Requires PCB real estate for leaded mounting; unsuitable for automated SMT lines | Select when manual assembly or legacy through-hole compatibility is required |
| MMBZ5240B | 10 V nominal, ±5 %, SOT-23 package; lower Ptot (350 mW); higher rdiff (170 Ω) | Less stable under load variation; limited surge capability (25 W) | Select only for ultra-compact layouts where 500 mW and 40 W ratings are not needed |
Compared with BZX55-C10, BZV55-C10,115 offers superior thermal performance in SMT assembly and tighter board-level integration; versus MMBZ5240B, it delivers 43 % higher continuous power and 60 % lower dynamic impedance for improved regulation fidelity.

FAQ
What is the maximum continuous forward current for BZV55-C10,115?
The absolute maximum forward current is 250 mA, but the device is intended for reverse-bias Zener operation. Forward conduction is only relevant during transient fault conditions or circuit startup; sustained forward bias exceeds design intent and risks thermal runaway.
Does BZV55-C10,115 require a series current-limiting resistor in regulation mode?
Yes - a series resistor is mandatory to limit Zener current to the recommended 5 mA test condition or within the 400–500 mW total power envelope. Typical values range from 1 kΩ to 10 kΩ depending on supply voltage and load current draw.
How does the +4.5 mV/K temperature coefficient affect long-term reference stability?
This coefficient means the Zener voltage increases by 4.5 mV per °C rise in junction temperature. Over a 50 °C ambient range, drift is ~225 mV - acceptable for non-precision applications but requires compensation in metrology-grade systems.
Can BZV55-C10,115 replace BZV55-B10 in existing designs?
No - BZV55-B10 has ±2 % tolerance (9.8–10.2 V), while BZV55-C10,115 has ±5 % (9.4–10.6 V). Substitution may cause out-of-spec reference voltage in circuits relying on tight initial accuracy, though it remains valid for general-purpose clamping.
