Product details
Overview
PZU84-B13-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 13 V nominal breakdown voltage at IZ = 5 mA, with differential resistance of 80 Ω (max), temperature coefficient of +7.0 mV/K, and reverse current ≤0.1 μA at VR = 10 V - used for precision voltage reference and overvoltage clamping in automotive power rail monitoring circuits.
For engineers reviewing the PZU84-B13-QR datasheet, PZU84-B13-QR pinout, PZU84-B13-QR application, or PZU84-B13-QR equivalent, this page delivers verified Zener parameters including VZ, rdif, IR, thermal resistance, and AEC-Q101 qualification status - critical for automotive-grade voltage stabilization design.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its hard breakdown knee and low leakage current support accurate regulation in low-power sensor biasing and ECU supply supervision.
The device features two Zener series: B-series (e.g., PZU84-B13-QR) offers tighter ±2 % tolerance and optimized low-current stability, while C-series provides wider tolerance and intentional leakage tuning for noise-sensitive switching applications per AN90031.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 13 V at IZ = 5 mA - defines primary regulation point for 12 V automotive rail stabilization |
| Tolerance | ±2 % - ensures tight voltage accuracy across production batches for safety-critical monitoring |
| rdif | 80 Ω max at IZ = 5 mA - low dynamic impedance maintains regulation stability under transient load changes |
| IR | ≤0.1 μA at VR = 10 V - ultra-low leakage preserves battery life in always-on vehicle modules |
| SZ | +7.0 mV/K - positive temperature coefficient enables predictable drift compensation in wide-temperature ECUs |
| Ptot | 250 mW - sufficient for continuous regulation in SOT23 footprint without heatsinking on FR4 PCB |
| Rth(j-a) | 500 K/W - thermal resistance confirms suitability for ambient operation up to +105 °C in engine bay proximity |
Pinout & Package
Package: SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), qualified per AEC-Q101 for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward conduction terminal; connected to lower-potential side in Zener regulation configuration |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or solder mask required |
| 3 | Cathode (K) | Reverse-bias input terminal; tied to regulated voltage node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VZ tolerance | Enables direct replacement in high-accuracy 12 V rail monitors without calibration adjustment |
| AEC-Q101 qualification | Validated for automotive under-hood environments including thermal cycling, humidity, and mechanical shock |
| Hard breakdown knee | Ensures sharp, repeatable turn-on behavior critical for overvoltage protection response time |
| Ultra-low IR (≤0.1 μA) | Minimizes standby current draw in always-on telematics and gateway modules |
| Low rdif (80 Ω max) | Reduces output voltage deviation during 1–10 mA load transients in microcontroller reset circuits |
Applications
| Engine Control Unit (ECU) Supply Monitoring | Automotive Sensor Biasing |
|---|---|
|
Use Scenario: Continuous monitoring of 12 V battery rail voltage in engine control units to trigger brown-out detection or limp-home mode. IC Role / Device Role / Timing Role: Zener diode provides stable 13 V reference to comparator input for precise undervoltage threshold detection. Use Value: ±2 % tolerance and +7.0 mV/K temperature coefficient allow accurate trip-point setting across −40 °C to +125 °C operating range. |
Use Scenario: Biasing of analog front-end circuitry for pressure, temperature, and oxygen sensors in exhaust and intake manifolds. IC Role / Device Role / Timing Role: Functions as low-drift voltage reference for sensor excitation and ADC reference scaling. Use Value: Ultra-low 0.1 μA leakage prevents signal offset errors in high-impedance sensor bridges at cold start. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | ±5 % tolerance, higher rdif (120 Ω), no AEC-Q101 qualification | Acceptable for non-automotive consumer electronics where cost > precision | Select only if AEC-Q101 compliance and <2 % VZ error are not required |
| MMSZ5243B | ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint) | Higher power handling but incompatible with space-constrained SOT23 layouts | Choose when thermal margin > board area constraints, and automotive qualification is secondary |
Compared with BZX84-C13 and MMSZ5243B, PZU84-B13-QR delivers tighter tolerance, lower leakage, and automotive qualification in the same SOT23 footprint - making it the sole option for AEC-compliant 13 V reference in compact ECU and BCM designs.

FAQ
What is the maximum reverse current (IR) specification for PZU84-B13-QR at 10 V?
The maximum reverse current is 0.1 μA at VR = 10 V and Tj = 25 °C, confirmed in Table 8 of the datasheet. This ultra-low leakage supports battery-sensitive automotive modules such as telematics and keyless entry systems where standby current must remain below 1 μA.
Does PZU84-B13-QR support reflow soldering, and what footprint is recommended?
Yes - it is qualified for lead-free reflow soldering using the standard SOT23 footprint shown in Figure 10: 0.6 mm solder land width (3×), 0.7 mm solder paste stencil opening (3×), with 1.9 mm pin pitch. The device meets JEDEC J-STD-020 moisture sensitivity level 1.
How does the +7.0 mV/K temperature coefficient affect regulation accuracy over temperature?
At 13 V nominal VZ, a +7.0 mV/K coefficient results in +0.84 V drift from −40 °C to +125 °C (165 K ΔT). This predictable positive drift allows system designers to compensate threshold voltages in comparator-based monitoring circuits without trimming components.
Is Pin 2 truly unconnected, and can it be left floating on the PCB?
Yes - Pin 2 is internally not connected (n.c.), as stated in Table 2 and confirmed in the simplified outline graphic. It must remain electrically isolated: no copper trace, no solder mask opening, and no thermal pad connection - ensuring no parasitic coupling or thermal path interference.
