Product details
Overview
BZV55-C24,135 from Nexperia is a 24 V ±5 % 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 sensor interfaces and power supply feedback networks.
For engineers reviewing the BZV55-C24,135 datasheet, BZV55-C24,135 pinout, BZV55-C24,135 application, or BZV55-C24,135 equivalent, key selection criteria include nominal Zener voltage (24 V), tolerance (±5 %), differential resistance (≤70 Ω at IZ = 5 mA), temperature coefficient (+15.9 to +22.0 mV/K), and SOD80C thermal resistance (Rth(j-a) = 380 K/W).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage under varying load and temperature conditions. Its 24 V nominal Zener voltage is specified at IZ = 5 mA with a typical differential resistance of 60 Ω and a positive temperature coefficient ranging from +15.9 to +22.0 mV/K.
The device uses a low-capacitance structure (≤55 pF at f = 1 MHz, VR = 0 V) and supports surge handling up to 40 W for 100 µs pulses. It is designed for operation within −65 °C to +200 °C junction temperature range and exhibits reverse leakage current ≤100 nA at VR = 0.7 × VZ(nom).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.8 V to 25.6 V at IZ = 5 mA - defines stable regulation point across manufacturing tolerance |
| Differential Resistance (rdif) | 60 Ω (typ), 250 Ω (max) at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +15.9 to +22.0 mV/K - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C on ceramic substrate - sets maximum continuous DC power handling |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for 100 µs square wave - enables transient overvoltage clamping without failure |
| Reverse Leakage Current (IR) | ≤100 nA at VR = 16.8 V (0.7 × 24 V) - ensures minimal quiescent current in high-impedance bias networks |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports use as low-drop rectifier or ESD clamp in forward mode |
Pinout & Package
Hermetically sealed glass SOD80C 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 |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation |
| 2 | Anode | Connected to ground or lower-potential rail; establishes reference polarity for breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective regulation where tight voltage accuracy is not required, e.g., non-critical biasing |
| Low differential resistance (60 Ω typ) | Reduces output voltage variation under load changes, improving regulation stability in feedback loops |
| SOD80C hermetic glass package | Provides moisture immunity and long-term parameter stability vs. plastic-packaged Zeners |
| Positive temperature coefficient (+15.9 to +22.0 mV/K) | Allows predictable compensation when paired with negative-TC components in reference circuits |
| 40 W non-repetitive surge rating | Supports transient suppression in low-energy protection circuits without external TVS devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C24,115 | Same 24 V ±5 % rating but in SOD123 package; higher Ptot = 500 mW, Rth(j-a) = 300 K/W | Better thermal performance in high-density layouts; larger footprint may conflict with space-constrained designs | Select when board layout allows SOD123 and improved thermal margin is needed over SOD80C |
| MMBZ5249BS-7-F | 24 V ±5 % in SOT-323; Ptot = 300 mW, rdif = 80 Ω (max), Rth(j-a) = 450 K/W | Smaller footprint but lower power handling and higher impedance limit use to ultra-low-current references | Select only for battery-powered systems requiring minimal PCB area and <1 mA Zener current |
Compared with BZV55-C24,135, the BZT52-C24,115 offers superior thermal resistance and identical electrical specs in a larger package, while the MMBZ5249BS-7-F trades power capability and regulation accuracy for miniaturization-making the BZV55-C24,135 optimal for general-purpose 24 V regulation where SOD80C size and hermetic reliability are prioritized.

FAQ
What is the maximum continuous Zener current for BZV55-C24,135 at 25 °C ambient?
The device supports up to 20.8 mA continuous Zener current at 25 °C ambient when mounted on a 10 × 10 × 0.6 mm ceramic substrate, calculated from Ptot = 500 mW and VZ ≈ 24 V. Derating is required above 50 °C ambient per the thermal resistance specification of 380 K/W.
Can BZV55-C24,135 be used in place of a 24 V Zener with tighter tolerance?
No-it is specified for ±5 % tolerance (22.8 V to 25.6 V), unlike ±2 % BZV55-B24 variants (23.5 V to 24.5 V). Substituting it into circuits requiring tighter regulation will introduce up to ±1.2 V error at nominal current, potentially violating downstream voltage thresholds.
How does the positive temperature coefficient affect circuit design?
The +15.9 to +22.0 mV/K coefficient causes VZ to increase ~0.5 V over a 25 °C to 75 °C junction temperature rise. This must be compensated in precision references-e.g., by pairing with a negative-TC component or selecting operating current to minimize TC sensitivity.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes-the SOD80C outline is qualified for lead-free reflow per JEDEC J-STD-020. Recommended profile includes peak temperature ≤260 °C for ≤10 seconds, with ramp rates ≤3 °C/s pre- and post-peak, matching standard Class 3 assembly requirements for industrial-grade boards.
