Nexperia USA Inc. NZX3V0C,133

Overview

NZX3V0C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 3.0 V nominal Zener voltage with ±0.2 V tolerance, 100 Ω typical differential resistance at I_Z = 5 mA, and ≤10 µA reverse leakage current. It operates across −55 °C to +175 °C ambient temperature and delivers stable reference voltage in low-power analog supply rails and overvoltage protection circuits.

For engineers reviewing the NZX3V0C,133 datasheet, NZX3V0C,133 pinout, NZX3V0C,133 application, or NZX3V0C,133 equivalent, this component serves as a cost-effective, thermally robust, axial-leaded Zener solution for fixed-voltage clamping, biasing, and reference generation where tight voltage accuracy and low thermal drift are required in space-constrained industrial and automotive-adjacent designs.

Technical Context

This Zener diode functions in reverse-biased breakdown mode, maintaining a stable 3.0 V reference across a 5 mA test current with minimal voltage variation due to its low 100 Ω differential resistance and low temperature coefficient (typical ±2 mV/K near 3 V). Its hermetic glass package ensures long-term stability and moisture immunity under thermal cycling.

The device complies with IEC 60134 absolute maximum ratings, supports continuous forward current up to 250 mA, and exhibits a junction-to-ambient thermal resistance of 380 K/W on FR4 PCB-enabling reliable operation without heatsinking in low-dissipation (<500 mW) applications.

FAQ

What is the maximum continuous reverse voltage the NZX3V0C,133 can withstand before breakdown?

The NZX3V0C,133 is specified for Zener breakdown at 3.0–3.2 V under 5 mA test current. Its rated reverse voltage (V_R) is 1 V per datasheet Table 8, meaning it maintains ≤10 µA leakage below 1 V. Applying >3.2 V continuously will initiate controlled breakdown; sustained operation above 3.2 V is intentional and within specification as long as power dissipation remains ≤500 mW and junction temperature stays ≤175 °C.

Can NZX3V0C,133 replace a 3.3 V Zener diode in a voltage reference circuit?

No-it is not a drop-in replacement for 3.3 V Zeners. With a nominal 3.0 V Zener voltage (3.0–3.2 V range), using it in place of a 3.3 V part introduces a systematic −0.1 to −0.3 V offset. This may cause undervoltage faults in 3.3 V rail monitors or incorrect ADC reference scaling. For 3.3 V applications, NZX3V3C (3.3–3.5 V) is the correct variant in the same series.

How does the SOD27 hermetic package improve long-term reliability versus plastic-packaged Zeners?

The SOD27 glass-metal seal prevents moisture ingress and halogen-induced corrosion that degrade Zener voltage stability in plastic packages over time. Accelerated life testing shows <0.1% V_Z shift after 1000 hours at 155 °C for NZX3V0C,133, versus >1% drift common in epoxy-molded equivalents-critical for medical, aerospace, and infrastructure systems requiring 15+ year field life.

Is NZX3V0C,133 suitable for automotive applications?

NZX3V0C,133 is not AEC-Q200 qualified and lacks automotive-specific stress testing (e.g., temperature cycling, vibration, sulfur exposure). While its −55 °C to +175 °C rating covers under-hood temperatures, Nexperia explicitly states non-automotive qualification in the datasheet legal section. Use requires full customer validation; for production automotive systems, AEC-Q200-compliant alternatives like PZU3.0B2A should be selected instead.
