Product details
Overview
BZV55-C33,115 from Nexperia is a 33 V ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 400 mW steady-state power dissipation at ≤50 °C ambient and 40 W non-repetitive peak reverse power (100 µs square wave), used for precision voltage reference and low-power regulation in analog sensor interfaces and power supply feedback loops.
For engineers reviewing the BZV55-C33,115 datasheet, BZV55-C33,115 pinout, BZV55-C33,115 application, or BZV55-C33,115 equivalent, key selection criteria include nominal Zener voltage (33 V), differential resistance (75 Ω typ. at IZ = 2 mA), temperature coefficient (+23.3 mV/K typ.), reverse leakage (<50 nA at 0.7×VZ), and SOD80C thermal resistance (300 K/W junction-to-solder-point).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its 33 V nominal Zener voltage is specified at 2 mA test current with ±5 % tolerance, and its positive temperature coefficient (+23.3 mV/K) ensures predictable drift over operating range.
The device exhibits low differential resistance (75 Ω typ. at IZ = 2 mA) and minimal capacitance (45 pF at 1 MHz, 0 V bias), enabling stable regulation in high-frequency feedback paths. It is qualified for operation from −65 °C to +200 °C junction temperature and supports non-repetitive surge handling up to 40 W for 100 µs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V nominal, ±5 % tolerance (31.0 V to 35.0 V), specified at IZ = 2 mA - defines precise regulation point in feedback networks |
| Differential Resistance (rdif) | 75 Ω typical at IZ = 2 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +23.3 mV/K typical - quantifies voltage drift per degree Celsius, critical for temperature-stable references |
| Reverse Leakage Current (IR) | <50 nA at VR = 23.1 V (0.7×VZ) - ensures minimal quiescent current in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤50 °C - sets maximum continuous DC power handling on standard PCB layout |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - enables transient overvoltage clamping without failure |
| Package | SOD80C: hermetically sealed glass SMD, 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height - provides moisture immunity and reliable reflow soldering |
Pinout & Package
SOD80C is a two-terminal surface-mount glass package with axial lead configuration; cathode identified by a colored band. The device has no internal circuitry beyond the Zener junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated voltage node; reverse-biased during Zener operation; marking band confirms polarity for correct PCB orientation |
| 2 (unbanded end) | Anode | Connected to ground or lower-potential rail; completes reverse-bias path; must be routed with low-inductance trace in noise-sensitive applications |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass SMD packaging | Eliminates moisture ingress and long-term parameter drift, enabling >10-year stability in industrial environments |
| ±5 % Zener voltage tolerance | Supports cost-optimized designs where tight regulation is balanced against calibration overhead and BOM count |
| Low differential resistance (75 Ω typ.) | Reduces output voltage variation under ±1 mA load current changes - critical for ADC reference buffers and op-amp biasing |
| Controlled positive temperature coefficient | Enables predictable, linear drift compensation when paired with negative-TC components in reference circuits |
| 40 W non-repetitive surge rating | Provides robust ESD and transient suppression capability without external TVS, simplifying protection in low-energy nodes |
Applications
| Industrial Sensor Signal Conditioning | Low-Power SMPS Feedback Reference |
|---|---|
|
Use Scenario: Stabilizing excitation voltage for resistive bridge sensors (e.g., strain gauges, RTDs) in PLC analog input modules. IC Role / Device Role / Timing Role: Zener diode provides fixed 33 V reference for constant-current source driving the bridge, rejecting supply ripple and temperature-induced drift. Use Value: Enables 0.1 % full-scale accuracy over −40 °C to +85 °C ambient due to low rdif and known SZ, eliminating need for active reference ICs. |
Use Scenario: Setting output voltage in isolated flyback converters with optocoupler feedback, where primary-side regulation requires stable reference. IC Role / Device Role / Timing Role: Acts as secondary-side shunt reference, sinking current into optocoupler LED to close voltage regulation loop. Use Value: Delivers stable 33 V threshold with <50 nA leakage, minimizing standby power and improving light-coupling linearity across temperature. |
| Microcontroller Reset Circuitry | ADC Voltage Reference Buffer |
|
Use Scenario: Generating clean, temperature-compensated reset threshold for 3.3 V or 5 V microcontrollers in battery-powered edge devices. IC Role / Device Role / Timing Role: Zener clamps RC-generated reset pulse to precise 33 V level before divider network scales it to MCU reset pin voltage. Use Value: Ensures deterministic reset timing across −25 °C to +70 °C with <1 % hysteresis shift, avoiding spurious resets during thermal cycling. |
Use Scenario: Providing low-noise, low-drift reference for 12-bit SAR ADCs in portable medical instrumentation. IC Role / Device Role / Timing Role: Supplies regulated 33 V to external reference buffer amplifier, which drives ADC REF+ input with minimal dynamic loading. Use Value: Achieves <0.05 % integral nonlinearity contribution via 75 Ω rdif and 45 pF capacitance, preserving ENOB in sub-100 kSPS sampling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5263BLT1G | 33 V ±5 %, SOT-23 package, 200 mW Ptot, rdif = 95 Ω typ., higher thermal resistance (450 K/W) | Lower power handling and poorer thermal performance limit use to <10 mA continuous current | Select only when board space is constrained and power dissipation remains below 150 mW |
| BZX84-C33 | 33 V ±5 %, SOT-23 package, 300 mW Ptot, rdif = 80 Ω typ., plastic encapsulation (non-hermetic) | Higher humidity sensitivity and long-term VZ drift risk in humid industrial enclosures | Prefer for consumer-grade cost-sensitive designs where hermeticity is not required |
Compared with MMBZ5263BLT1G and BZX84-C33, BZV55-C33,115 delivers superior thermal reliability (300 K/W vs. ≥450 K/W), hermetic stability, and 400 mW continuous power - making it the preferred choice for industrial analog signal chains requiring long-term calibration integrity.

FAQ
What is the maximum continuous forward current for BZV55-C33,115?
The absolute maximum forward current is 250 mA per datasheet limiting values (Table 5). However, this device is intended for reverse-bias Zener operation; forward conduction is only relevant during transient conditions or incorrect polarity events. Continuous forward bias exceeds safe operating area and risks thermal runaway.
Can BZV55-C33,115 be used in place of a 3.3 V Zener diode?
No - BZV55-C33,115 is a 33 V Zener diode, not 3.3 V. Its nominal breakdown voltage is 33 V ±5 %, verified in Table 9 of the datasheet. Using it as a 3.3 V reference would result in no conduction below ~31 V and catastrophic failure above rated power. Select BZV55-C3V3,115 for 3.3 V regulation.
Is the SOD80C package compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C outline (Figure 6) and soldering footprints (Figures 7–8) are validated for peak temperatures up to 260 °C, with thermal resistance data confirming safe operation under standard 60-second above-217 °C dwell time.
How does the temperature coefficient affect long-term accuracy in a 25 °C to 75 °C operating range?
With a typical +23.3 mV/K coefficient, BZV55-C33,115 drifts +1.165 V over a 50 K rise (25 °C → 75 °C). At 33 V nominal, this equals +3.53 % full-scale shift. For applications requiring <0.5 % total drift, external compensation (e.g., series NTC resistor) or tighter-tolerance variants (BZV55-B33) are recommended.
