Product details
Overview
PZU84-C7V5R from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 package, providing 7.06 V to 7.84 V nominal breakdown voltage at IZ = 5 mA, with differential resistance ≤60 Ω and reverse leakage ≤0.5 μA, used for precision voltage reference and overvoltage clamping in low-power analog circuits.
For engineers reviewing the PZU84-C7V5R datasheet, PZU84-C7V5R pinout, PZU84-C7V5R application, or PZU84-C7V5R equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at low bias current, thermal resistance (Rth(j-sp) = 330 K/W), junction temperature limit (150 °C), and SOT23 footprint compatibility with automated assembly.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its hard breakdown knee and very low leakage current (<0.5 μA at VR = 7.5 V) support high-accuracy regulation in battery-powered and signal-conditioning circuits.
The device exhibits a positive temperature coefficient of +2.5 mV/K at IZ = 5 mA, enabling predictable drift compensation in multi-diode references. It is rated for non-repetitive peak reverse power dissipation of 40 W (tp = 100 μs), supporting transient suppression in low-energy surge scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.06 V to 7.84 V at IZ = 5 mA - defines stable regulation window for 7.5 V nominal reference |
| Differential Resistance (rdif) | ≤60 Ω at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 7.5 V - enables ultra-low quiescent current operation in always-on circuits |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports use as polarity-sensitive clamp or ESD protection element |
| Total Power Dissipation (Ptot) | 250 mW on FR4 PCB - sets maximum continuous DC power handling in standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - allows deployment in extended industrial ambient environments |
| Thermal Resistance (Rth(j-sp)) | 330 K/W - quantifies heat transfer efficiency from junction to cathode solder point |

SOT23 plastic surface-mounted package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, 3-terminal configuration with anode (Pin 1), not-connected (Pin 2), and cathode (Pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; reverse-biased connection to regulated node |
| 2 | Not Connected (n.c.) | Internally unconnected terminal; must remain floating or grounded per layout rules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5 | Same SOT23 package and 7.5 V nominal rating, but ±5 % tolerance and higher typical rdif (100 Ω vs. 60 Ω) | Higher dynamic impedance increases output sensitivity to load changes; less suitable for precision references | Select when legacy BOM alignment or distributor stock availability outweighs low-impedance requirement |
| MMSZ5235B | Same 7.5 V rating and ±5 % tolerance, but higher leakage (≤10 μA vs. ≤0.5 μA) and lower Ptot (350 mW vs. 250 mW) | Higher leakage degrades accuracy in high-Z feedback networks; higher power rating allows larger surge margin | Prefer for higher-surge environments where leakage is secondary to robustness, e.g., front-end protection stages |
Compared with BZX84-C7V5 and MMSZ5235B, PZU84-C7V5R delivers superior low-current regulation stability (≤0.5 μA leakage, ≤60 Ω rdif) and optimized thermal performance (Rth(j-sp) = 330 K/W), making it preferred for precision analog references and micropower designs where voltage accuracy and thermal predictability are critical.

FAQ
What is the maximum continuous forward current for PZU84-C7V5R?
The absolute maximum forward current is 200 mA per limiting values table. However, sustained operation above 10 mA is not recommended due to thermal constraints-forward conduction is typically limited to brief pulses or ESD protection duty cycles, not steady-state regulation.
Can PZU84-C7V5R be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficients and manufacturing spread, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated device or external series pass transistor with feedback control.
Is the "n.c." pin electrically isolated or internally tied to substrate?
Pin 2 is fully unconnected-no internal bond wire or die attachment. It must remain floating in circuit layout; grounding or routing signals to this pin risks mechanical stress, solder bridging, or unintended parasitic coupling.
How does temperature affect the Zener voltage of PZU84-C7V5R?
At IZ = 5 mA, the temperature coefficient is +2.5 mV/K, meaning VZ increases by ~2.5 mV per degree Celsius rise. This positive drift is stable and repeatable, enabling predictable compensation in multi-diode reference strings.
