Product details
Overview
NZX7V5C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 7.5 V nominal Zener voltage with ±0.4 V tolerance (7.3–7.7 V), 15 Ω typical differential resistance at IZ = 5 mA, and ≤1 µA reverse leakage at VR = 5 V - used in low-power reference and overvoltage clamp circuits in industrial power supplies and sensor signal conditioning.
For engineers reviewing the NZX7V5C,133 datasheet, NZX7V5C,133 pinout, NZX7V5C,133 application, or NZX7V5C,133 equivalent, this device is selected for stable 7.5 V regulation under low-current conditions (IZ = 5 mA), where low thermal drift, hermetic reliability, and axial-leaded through-hole mounting are required in non-automotive embedded systems.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified Zener voltage of 7.3–7.7 V at 5 mA test current, exhibiting a temperature coefficient near zero at this bias point per Fig 4. Its junction-to-ambient thermal resistance is 380 K/W in free air on FR4 PCB, limiting continuous power dissipation to 500 mW at Tamb ≤25 °C.
The device uses a glass-passivated silicon junction in an axial-leaded SOD27 package with cathode indicated by a band. It complies with IEC 60134 absolute maximum ratings, supporting ambient temperatures from −55 °C to +175 °C and storage up to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.3–7.7 V at IZ = 5 mA - defines precise clamping/reference level in feedback or protection circuits |
| Differential Resistance (rdif) | 15 Ω typical at IZ = 5 mA - determines regulation stiffness and output impedance under load variation |
| Reverse Leakage (IR) | ≤1 µA at VR = 5 V - ensures minimal standby current in high-impedance bias networks |
| Max Power Dissipation (Ptot) | 500 mW at Ttp ≤25 °C - sets upper bound for continuous DC or pulsed power handling |
| Junction Temperature (Tj) | −55 to +175 °C - enables operation in extended industrial environments without derating below −40 °C |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - supports use as low-drop rectifier or ESD path in bidirectional configurations |
Pinout & Package
Package: SOD27 (SC-40), hermetically sealed axial-leaded glass package with 2 leads; cathode identified by a colored band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node or voltage reference point; polarity-sensitive for reverse-bias operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes Zener conduction path during breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or harsh environments |
| Low differential resistance | 15 Ω typical ensures tight voltage regulation across ±1 mA load current changes |
| Low leakage current | ≤1 µA at 5 V reverse bias minimizes error in high-impedance reference dividers |
| Wide operating temperature range | −55 °C to +175 °C allows deployment in industrial motor drives and outdoor instrumentation |
Applications
| Power Supply Reference | Sensor Signal Clamping |
|---|---|
Use Scenario: Providing stable 7.5 V reference for op-amp comparators in isolated DC-DC converter feedback loops. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, absorbing excess current to maintain fixed potential at error amplifier input. Use Value: Enables ±1% output regulation accuracy despite input ripple and load transients due to low rdif and stable VZ. |
Use Scenario: Protecting analog front-end inputs of temperature sensors from ESD or transient overvoltage. IC Role / Device Role / Timing Role: Bidirectional clamping element-Zener conducts above 7.5 V, forward diode conducts below −0.7 V. Use Value: Limits input swing to safe range without loading sensor output, leveraging low leakage and fast response (<300 µs pulse capability). |
| Microcontroller Reset Circuit | Current Source Biasing |
Use Scenario: Generating clean reset threshold in brown-out detection circuits for 8-bit microcontrollers. IC Role / Device Role / Timing Role: Zener establishes precise trip voltage for external reset IC or comparator input. Use Value: Delivers repeatable 7.5 V trigger point across temperature (−40 to +85 °C), critical for deterministic system startup. |
Use Scenario: Setting bias current for LED drivers or transistor amplifiers via constant-voltage drop across series resistor. IC Role / Device Role / Timing Role: Provides stable voltage reference to define IB or ILED independent of supply variation. Use Value: Maintains ±2% current stability over 10–100 mA supply ranges due to low rdif and minimal tempco at 5 mA. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C7V5 | Plastic DO-35 package; 7.3–7.7 V VZ; 20 Ω rdif; 1 µA IR | Lower cost but higher thermal resistance (450 K/W); unsuitable for >85 °C ambient | Select when cost sensitivity outweighs hermetic reliability and extended temperature needs |
| 1N4733A | DO-41 package; 7.4–7.6 V VZ; 10 Ω rdif; 5 µA IR; 1 W Ptot | Higher power rating but larger footprint and higher leakage limits precision biasing | Select when >500 mW dissipation or PCB space permits larger axial package |
Compared with BZX55-C7V5 and 1N4733A, NZX7V5C,133 offers superior long-term stability and wider temperature operation due to hermetic sealing and optimized low-leakage design, making it preferred for mission-critical industrial references where parameter drift must be minimized over 10+ years.

FAQ
What is the Zener voltage tolerance for NZX7V5C,133?
The NZX7V5C,133 has a nominal Zener voltage of 7.5 V with a guaranteed range of 7.3 V to 7.7 V at IZ = 5 mA and Tj = 25 °C, corresponding to the 'C' tolerance grade per Table 8 of the datasheet.
Can NZX7V5C,133 be used in surface-mount designs?
No - NZX7V5C,133 uses the axial-leaded SOD27 (SC-40) glass package intended for through-hole mounting only; it lacks solder pads or terminations compatible with reflow or wave soldering processes.
What is the maximum forward current rating?
The absolute maximum forward current is 250 mA per Table 5; however, forward conduction is not its primary function - the device is rated for ≤1.5 V forward voltage at 200 mA, supporting limited bidirectional clamping use.
Does NZX7V5C,133 meet automotive qualification standards?
No - the datasheet explicitly states this is a non-automotive qualified product; it is neither AEC-Q200 tested nor rated for automotive temperature or reliability requirements.
