Product details
Overview
NZX13C,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 13 V nominal working voltage with ±5% tolerance, 35 Ω typical differential resistance at IZ = 5 mA, and ≤8 µA reverse current at VR = 10.5 V - used in low-power reference and overvoltage protection circuits in industrial power supplies.
For engineers reviewing the NZX13C,133 datasheet, NZX13C,133 pinout, NZX13C,133 application, or NZX13C,133 equivalent, this device serves as a stable, low-leakage, axial-leaded Zener solution where thermal stability, tight voltage tolerance, and low dynamic impedance are critical in analog sensing and DC rail clamping designs.
Technical Context
This Zener operates in reverse breakdown mode with a nominal Zener voltage of 13 V (min 12.9 V, max 13.4 V at IZ = 5 mA), exhibiting a temperature coefficient near zero crossing in the 10–15 V range - confirmed by Fig 4 showing SZ ≈ 0 mV/K at IZ ≈ 5 mA. Its low leakage (≤8 µA at VR = 10.5 V) and low differential resistance (35 Ω typ.) support stable reference generation under light-load conditions.
The device uses a glass-encapsulated axial lead structure with cathode indicated by a band, rated for Ptot ≤ 500 mW at Tamb ≤ 25 °C and junction temperature up to 175 °C. Thermal resistance from junction to ambient is 380 K/W in free air on FR4 PCB with 8 mm leads - defining its derating envelope in compact linear regulator feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.9 V to 13.4 V at IZ = 5 mA - defines precise clamping threshold for 12 V rail protection |
| Differential Resistance rdif | 35 Ω typical - ensures minimal output voltage shift under load variation in reference circuits |
| Reverse Current IR | ≤8 µA at VR = 10.5 V - enables low quiescent current operation in battery-backed systems |
| Total Power Dissipation Ptot | 500 mW maximum at Tamb ≤ 25 °C - sets thermal limit for continuous DC regulation without heatsinking |
| Junction Temperature Tj | −65 °C to +175 °C - supports operation in extended industrial environments including motor control enclosures |
| Forward Voltage VF | ≤1.5 V at IF = 200 mA - allows use as polarity-sensitive clamp or ESD path in bidirectional protection |
Pinout & Package
Hermetically sealed SOD27 (SC-40) axial glass package with 2 leads: cathode marked by a colored band; leads tinned for solderability; body diameter 1.85 mm max, length 4.25 mm max, lead spacing 25.4 mm min.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated node; reverse-biased during Zener operation; carries breakdown current |
| 2 (unmarked end) | Anode | Connected to ground or lower potential; completes bias path; handles forward conduction if needed |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift - critical for 10+ year field reliability in telecom infrastructure |
| Low differential resistance | 35 Ω typical at 5 mA - maintains <±10 mV regulation error across ±1 mA load change in feedback networks |
| Low leakage current | ≤8 µA at 10.5 V - avoids loading high-impedance sensor references or microcontroller reset inputs |
| Tight voltage tolerance | ±5% (C grade) - eliminates need for external trimming in cost-sensitive industrial power monitors |
Applications
| Industrial Power Monitor | Microcontroller Reset Circuit |
|---|---|
Use Scenario: Monitoring 12 V DC supply in PLC I/O modules to trigger fault alerts when voltage deviates beyond ±5%. IC Role / Device Role / Timing Role: Zener diode provides stable 13 V reference for comparator input against which supply is measured. Use Value: Tight 12.9–13.4 V tolerance ensures accurate trip point; low leakage avoids false triggers from high-impedance comparator inputs. |
Use Scenario: Generating a clean, noise-immune reset signal for an ARM Cortex-M0 MCU during cold start and brownout. IC Role / Device Role / Timing Role: Acts as voltage threshold detector in RC-based reset generator, clamping capacitor voltage at 13 V. Use Value: Low rdif prevents droop during capacitor discharge; glass package ensures long-term stability of reset threshold over temperature. |
| Linear Regulator Feedback | Overvoltage Protection Clamp |
Use Scenario: Setting output voltage of a discrete NPN pass transistor regulator delivering 12.5 V @ 100 mA. IC Role / Device Role / Timing Role: Provides precision reference for op-amp error amplifier feedback loop. Use Value: 35 Ω rdif minimizes load-induced error; 500 mW rating accommodates transient overload without thermal runaway. |
Use Scenario: Protecting downstream 12 V logic circuitry from transient surges exceeding 14 V in automotive accessory modules. IC Role / Device Role / Timing Role: Shunts excess energy to ground when input exceeds 13.4 V, limiting peak voltage seen by ICs. Use Value: Fast response (<100 ns) due to low junction capacitance; axial leads allow direct placement across input rails with minimal trace inductance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C13 | Same 13 V nominal, but plastic DO-35 package; rdif = 40 Ω; IR ≤ 5 µA at 10.5 V | Lower cost, less hermetic - suitable for non-harsh environments; higher thermal resistance (450 K/W) | Select for cost-sensitive consumer products where long-term humidity exposure is not expected |
| 1N4742A | 12 V nominal (not 13 V); 1 W rating; rdif = 9 Ω; IR ≤ 5 µA at 9 V | Higher power handling but looser 5% tolerance; requires heatsinking above 300 mW | Select only if 12 V clamping is acceptable and >500 mW dissipation is required |
Compared with BZX55-C13 and 1N4742A, NZX13C,133 offers superior long-term stability via hermetic sealing and tighter regulation at 13 V, making it preferred for industrial monitoring and reset circuits where parameter drift must be minimized over 15+ years.

FAQ
What is the Zener voltage tolerance for NZX13C,133?
The NZX13C,133 has a nominal Zener voltage of 13 V with a guaranteed range of 12.9 V to 13.4 V at IZ = 5 mA, corresponding to the 'C' grade tolerance of ±5% as defined in Table 8 of the datasheet.
Can NZX13C,133 be used in surface-mount designs?
No - NZX13C,133 uses an axial-leaded SOD27 (SC-40) glass package intended for through-hole mounting; it lacks SMD-compatible terminations or reflow-rated construction, and its lead pitch and body geometry are incompatible with standard pick-and-place or reflow processes.
What is the maximum continuous forward current rating?
The absolute maximum forward current is 250 mA per Table 5, but the datasheet specifies VF ≤ 1.5 V at IF = 200 mA (Table 1), indicating safe continuous operation up to 200 mA with adequate PCB copper area for thermal dissipation.
How does thermal resistance affect derating at elevated ambient temperatures?
With Rth(j-a) = 380 K/W in free air, power dissipation must be linearly derated above 25 °C ambient: at 75 °C, max Ptot drops to 375 mW; at 125 °C, it falls to 250 mW - ensuring Tj remains ≤ 175 °C per Table 5 limiting values.
