Product details
Overview
NZX9V1E,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation and reference functions at 9.1 V nominal Zener voltage with ±5% tolerance (8.7–9.1 V), 20 Ω typical differential resistance at IZ = 5 mA, and ≤0.5 µA reverse leakage current at VR = 7.2 V. It operates across −55 °C to +175 °C ambient and supports general-purpose regulation in low-power analog circuits.
For engineers reviewing the NZX9V1E,133 datasheet, NZX9V1E,133 pinout, NZX9V1E,133 application, or NZX9V1E,133 equivalent, key selection criteria include Zener voltage accuracy, thermal stability over temperature, low dynamic impedance for ripple suppression, and axial-leaded glass-package reliability in high-reliability industrial sensing and power supply feedback paths.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 9.1 V at 5 mA test current, exhibiting a temperature coefficient near zero (±2 mV/K typical) in the 8–10 V range-enabling stable reference performance without external compensation. Its low 20 Ω differential resistance ensures minimal output voltage variation under load shifts.
The device uses a hermetically sealed glass package (SOD27/SC-40) with axial leads, providing superior moisture resistance and long-term parameter stability versus plastic-packaged alternatives. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous power dissipation to 500 mW at Tamb ≤ 25 °C per absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.7–9.1 V at IZ = 5 mA - defines precise clamping/reference level in feedback loops and voltage references |
| Differential Resistance (rdif) | 20 Ω typical at IZ = 5 mA - determines output impedance and ripple rejection capability |
| Reverse Leakage Current (IR) | ≤0.5 µA at VR = 7.2 V - ensures minimal standby power loss and high-impedance biasing integrity |
| Power Dissipation (Ptot) | 500 mW maximum at Ttp ≤ 25 °C - sets upper bound for continuous regulation power handling |
| Junction Temperature (Tj) | −55 °C to +175 °C - enables operation in extended-temperature industrial and automotive-adjacent environments |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - supports use as low-drop rectifier or clamp in dual-polarity protection schemes |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with cathode band marking; lead length ≤ 8 mm when mounted on FR4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity marker (band) identifies this terminal for correct orientation in series-shunt regulation |
| 2 | Anode | Connected to ground or lower potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and parameter drift over decades, critical for long-life instrumentation and aerospace-qualified designs |
| Low differential resistance | 20 Ω typical ensures <10 mV output shift per 0.5 mA load change-ideal for precision reference buffering |
| Low leakage current | ≤0.5 µA at 7.2 V enables high-impedance bias networks and battery-powered sensor nodes with negligible quiescent drain |
| Wide operating temperature | −55 °C to +175 °C ambient rating supports deployment in engine control units, downhole tools, and industrial motor drives |
Applications
| Industrial Power Supply Feedback | Overvoltage Protection Clamp |
|---|---|
|
Use Scenario: Regulating output voltage in isolated flyback converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Zener diode provides stable 9.1 V reference to TL431 shunt regulator input, setting primary-side feedback threshold. Use Value: Tight 8.7–9.1 V tolerance and low rdif minimize output voltage drift across line/load/temperature variations. |
Use Scenario: Protecting microcontroller I/O pins from transient surges exceeding 9.1 V. IC Role / Device Role / Timing Role: Acts as shunt clamp between signal line and ground, conducting only above 9.1 V to divert excess energy. Use Value: Hermetic glass construction ensures consistent clamping behavior after repeated surge events without parameter degradation. |
| Precision Analog Reference | Temperature-Stable Bias Generator |
|
Use Scenario: Generating fixed 9.1 V reference for ADC voltage scaling in data acquisition modules. IC Role / Device Role / Timing Role: Provides low-noise, low-drift DC reference for 12-bit SAR ADCs requiring <0.1% full-scale accuracy. Use Value: Near-zero temperature coefficient in 8–10 V range reduces calibration burden and improves measurement repeatability. |
Use Scenario: Establishing stable bias current for op-amp input stages in wide-temperature-range amplifiers. IC Role / Device Role / Timing Role: Used with series resistor to generate temperature-compensated current source for transistor biasing. Use Value: Low leakage (<0.5 µA) prevents current error accumulation in high-impedance bias networks at elevated temperatures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C9V1 | Plastic DO-35 package; 500 mW rating; ±5% VZ; rdif = 25 Ω typical | Lower moisture resistance and shorter lifetime stability vs. hermetic glass | Preferred where cost sensitivity outweighs long-term parameter drift requirements |
| 1N4739A | DO-41 package; 1 W rating; ±5% VZ; rdif = 8 Ω typical; higher power but larger footprint | Higher thermal mass delays response to fast transients; unsuitable for space-constrained PCBs | Chosen when >500 mW dissipation is needed and board area permits axial DO-41 placement |
Compared with BZX55-C9V1 and 1N4739A, NZX9V1E,133 delivers superior long-term stability and moisture immunity in compact SOD27 form, making it optimal for mission-critical analog references where parameter consistency over time and environment is non-negotiable.

FAQ
What is the maximum continuous reverse power dissipation for NZX9V1E,133?
The absolute maximum total power dissipation is 500 mW at lead temperature ≤ 25 °C. Derating is required above 25 °C at 4.2 mW/°C based on Rth(j-a) = 380 K/W. Operation above this limit risks permanent junction damage per IEC 60134 limiting values.
How is polarity identified on the NZX9V1E,133 package?
A single black band on the glass body marks the cathode (Pin 1). The unmarked end is the anode (Pin 2). This marking aligns with standard axial diode polarity conventions and must be observed during PCB layout to ensure correct reverse-bias connection.
Does NZX9V1E,133 have automotive qualification?
No. NZX9V1E,133 is not AEC-Q200 qualified or tested for automotive use. It is rated for industrial temperature range (−55 °C to +175 °C) but lacks automotive-specific stress testing, failure analysis, and traceability documentation required for vehicle applications.
Can NZX9V1E,133 be used in forward conduction mode?
Yes. With forward voltage ≤1.5 V at 200 mA, it functions as a low-drop rectifier or clamp in bidirectional protection circuits. However, its primary design intent and characterization are for reverse-bias Zener operation; forward characteristics are secondary and not optimized for switching.
