Product details
Overview
BZV55-C20,115 from Nexperia is a 20 V ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power, used for precision low-power voltage reference and regulation in analog signal conditioning circuits.
For engineers reviewing the BZV55-C20,115 datasheet, BZV55-C20,115 pinout, BZV55-C20,115 application, or BZV55-C20,115 equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, reverse leakage, and thermal resistance data directly tied to the SOD80C package and 20 V nominal regulation point.
Technical Context
This Zener diode operates in reverse breakdown with a nominal Zener voltage of 20 V at 5 mA test current, exhibiting a typical differential resistance of 60 Ω and a temperature coefficient of +12.3 mV/K - indicating positive drift with junction temperature rise. It maintains stable regulation under DC and transient conditions up to 100 µs pulse width.
Designed for low-power linear regulation, it features low reverse leakage (≤200 nA at VR = 7 V), 1.6 mm × 3.7 mm SOD80C footprint compatibility with standard reflow profiles, and thermal resistance from junction to ambient of 380 K/W in free air - enabling use in space-constrained PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 18.8 V to 21.2 V at IZ = 5 mA - defines regulation band for stable reference generation |
| Differential Resistance (rdif) | 60 Ω (typ) at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +12.3 mV/K (typ) - quantifies voltage drift per degree Celsius rise in junction temperature |
| Reverse Leakage (IR) | ≤200 nA at VR = 7 V - ensures minimal quiescent current in standby or high-impedance bias networks |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - supports surge suppression in transient overvoltage protection |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - enables thermal design margin estimation without heatsinking |
Pinout & Package
Hermetically sealed glass SOD80C package: 1.6 mm × 3.7 mm body, 0.3 mm profile, 2-terminal surface-mount construction with cathode indicated by marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective selection for non-critical reference applications without trimming |
| Low differential resistance (60 Ω typ) | Minimizes output voltage variation under load current changes up to ±1 mA |
| Hermetic glass SMD package | Ensures long-term stability and moisture resistance in industrial environments |

Applications
| Power Supply Reference | Analog Sensor Biasing |
|---|---|
Use Scenario: Providing stable 20 V reference for op-amp feedback networks in isolated DC-DC converter feedback loops. IC Role / Device Role / Timing Role: Zener diode acts as passive voltage reference source defining output regulation setpoint. Use Value: Delivers <±0.5 % output stability over 0–70 °C due to known +12.3 mV/K TC and low rdif. |
Use Scenario: Biasing bridge-based pressure sensors requiring precise excitation voltage in medical instrumentation. IC Role / Device Role / Timing Role: Regulator diode supplies fixed 20 V excitation to sensor Wheatstone bridge. Use Value: Enables <0.1 % full-scale error contribution from reference drift across operating temperature range. |
| Overvoltage Clamp | Signal Level Translation |
Use Scenario: Protecting ADC input pins from transient overvoltage events in industrial PLC analog input modules. IC Role / Device Role / Timing Role: Zener diode clamps input to 20 V during surges exceeding normal signal range. Use Value: Limits fault energy to <4 mJ using 40 W/100 µs PZSM rating, preventing latch-up or damage. |
Use Scenario: Shifting logic-level signals between 24 V control systems and 3.3 V microcontroller interfaces. IC Role / Device Role / Timing Role: Zener diode establishes 20 V clamp threshold for bidirectional level translation. Use Value: Maintains clean signal edges with <1 ns jitter impact due to low 60 pF capacitance at 0 V bias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C20,115 | Same 20 V ±5 % rating but in SOD123 package; higher Ptot = 500 mW at Tamb ≤ 65 °C; Rth(j-a) = 300 K/W | Better thermal performance in compact layouts; requires larger pad area than SOD80C | Select when board space allows larger footprint and higher ambient temperature operation is needed |
| MMSZ5249B-TP | 20 V ±5 % in SOD-123; Ptot = 500 mW; rdif = 30 Ω (typ); SZ = +11.5 mV/K | Lower dynamic impedance improves regulation accuracy under varying load; identical thermal metrics | Prefer for high-precision references where <0.1 % load regulation is required |
Compared with BZV55-C20,115, BZT52-C20,115 offers superior thermal dissipation in warmer environments, while MMSZ5249B-TP provides tighter regulation via lower differential resistance - both retain SMD compatibility but differ in package size and thermal interface requirements.

FAQ
What is the Zener test current for BZV55-C20,115?
The nominal Zener voltage of 20 V is specified at a test current of 5 mA, as confirmed in Table 8 of the Nexperia datasheet Rev. 5. This current establishes the operating point for measuring VZ, differential resistance, and temperature coefficient under standard conditions (Tj = 25 °C).
Can BZV55-C20,115 be used in series for higher voltage regulation?
No - BZV55-C20,115 is not characterized or guaranteed for series connection. Its ±5 % tolerance and mismatched temperature coefficients would cause uneven voltage distribution and thermal runaway risk. Use a single higher-voltage Zener or dedicated IC regulator instead.
What is the maximum forward voltage at 10 mA?
The forward voltage is guaranteed ≤0.9 V at IF = 10 mA, per Table 1 (Quick Reference Data). This value reflects the anode-to-cathode drop during forward conduction and is relevant for polarity protection or LED driver biasing configurations.
Does BZV55-C20,115 meet RoHS and REACH requirements?
Yes - BZV55-C20,115 is manufactured by Nexperia in compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as documented in Nexperia's official compliance statements and material declarations available via their website.
