Product details

Overview

BZV55-C36,115 from Nexperia is a ±5 % tolerance silicon Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 36 V nominal Zener voltage at 5 mA, with 45 Ω typical differential resistance and 0.8 A non-repetitive peak reverse current. It delivers stable reference voltage in low-power analog supply rails and overvoltage protection circuits.

For engineers reviewing the BZV55-C36,115 datasheet, BZV55-C36,115 pinout, BZV55-C36,115 application, or BZV55-C36,115 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint compatibility, and validated alternative parts for precision voltage regulation design.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 36 V reference across its terminals when biased above its knee current (IZ ≥ 5 mA). Its temperature coefficient of +26 mV/K at IZ = 5 mA indicates positive drift with junction temperature, requiring thermal compensation in high-stability references.

The device exhibits 45 Ω typical differential resistance at 5 mA, enabling tight regulation under load variation, and supports non-repetitive 100 µs surges up to 40 W-critical for transient suppression in power supply input stages.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	34.0 V to 38.0 V at I_Z = 5 mA - defines usable regulation range for 36 V nominal reference
Differential Resistance (r_dif)	45 Ω typical at I_Z = 5 mA - determines output impedance and load regulation error
Temperature Coefficient (S_Z)	+26 mV/K at I_Z = 5 mA - quantifies voltage drift per degree rise in junction temperature
Non-repetitive Peak Reverse Current (I_ZSM)	0.8 A at t_p = 100 µs - sets maximum single-pulse surge handling capability
Total Power Dissipation (P_tot)	500 mW at T_amb ≤ 50 °C on ceramic substrate - limits continuous DC biasing in PCB layout
Reverse Leakage (I_R)	50 nA at V_R = 25.2 V - ensures minimal quiescent current in standby mode
Forward Voltage (V_F)	0.9 V max at I_F = 10 mA - defines anode-cathode drop during forward conduction

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 marking band.

Pin/Terminal	Circuit Role	Design Meaning

Use Scenario: Providing stable 36 V reference for feedback loop in isolated DC-DC converter secondary side.

IC Role / Device Role / Timing Role: Zener diode acts as passive voltage reference for optocoupler-based error amplifier.

Use Value: Maintains ±1.5 % output regulation across -40 °C to +85 °C ambient with <10 ppm/°C drift contribution.

Use Scenario: Clamping surge transients on 36 V battery-backed sensor interface lines.

IC Role / Device Role / Timing Role: Shunts excess energy to ground during ESD or load-dump events.

Use Value: Limits voltage to ≤40 V for 100 µs, protecting downstream 3.3 V MCU GPIOs via series resistor.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX55-C36,113	Same SOD80C package, ±5 % tolerance, but 500 mW P_tot derated to 400 mW at T_amb > 50 °C	Lower thermal margin in enclosed enclosures above 50 °C ambient	Select if sourcing legacy stock; verify thermal layout meets 400 mW limit
MMSZ5245B-TP	Plastic SOD-123 package, ±5 %, 500 mW, 50 Ω r_dif, 25 mV/K S_Z	Higher moisture sensitivity and shorter long-term stability vs. hermetic glass	Prefer for cost-sensitive consumer designs where hermeticity is not required

Compared with BZV55-C36,115, BZX55-C36,113 offers identical electrical specs but reduced thermal headroom, while MMSZ5245B-TP trades hermetic reliability for lower cost and wider availability in plastic packaging.

FAQ

What is the maximum continuous Zener current for BZV55-C36,115 at 70 °C ambient?

At 70 °C ambient, total power dissipation is derated to 350 mW per thermal data sheet curves. With V_Z ≈ 36 V, maximum continuous Zener current is 9.7 mA (350 mW ÷ 36 V), assuming no additional power loss in series components.

Can BZV55-C36,115 be used in series for higher voltage reference generation?

Yes-two BZV55-C36,115 diodes in series yield ~72 V nominal reference. However, mismatched temperature coefficients (+26 mV/K each) cause cumulative drift; parallel operation is not recommended due to current-sharing instability.

Is the SOD80C package compatible with standard reflow soldering profiles?

Yes-the SOD80C outline meets JEDEC J-STD-020 requirements. Recommended reflow profile uses peak temperature ≤ 260 °C for ≤ 10 seconds, with preheat ramp rate ≤ 3 °C/s and cooling rate ≥ 1 °C/s.

How does the 0.8 A I_ZSM rating translate to practical surge protection capability?

At 0.8 A and 36 V, the diode clamps 28.8 W for 100 µs. In a 36 V system with 10 Ω series impedance, it limits transient voltage to ≤44 V-sufficient for ISO 7637-2 Pulse 1/2a protection when combined with appropriate RC filtering.
