Product details
Overview
PZU84-B13R from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, providing precise 13 V nominal regulation at 5 mA test current with 10 Ω typical differential resistance and −2.0 mV/K temperature coefficient. It operates across −55 °C to +150 °C ambient, supports 200 mA forward current, and delivers stable reference voltage for low-power analog circuits and overvoltage protection.
For engineers reviewing the PZU84-B13R datasheet, PZU84-B13R pinout, PZU84-B13R application, or PZU84-B13R equivalent, key selection criteria include Zener voltage tolerance (±2 %), low dynamic impedance (10 Ω @ 5 mA), thermal resistance (330 K/W junction-to-solder point), and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
The PZU84-B13R implements a silicon planar Zener structure optimized for sharp breakdown knee and low leakage-specifically designed for the B-series (±2 % tolerance) with hard breakdown characteristics per AN90031. Its 13 V nominal Zener voltage is specified at IZ = 5 mA with 10 Ω typical differential resistance and −2.0 mV/K temperature coefficient, ensuring stable regulation under varying load and temperature conditions.
Thermal performance is defined by Rth(j-sp) = 330 K/W (junction-to-solder point of cathode tab) and Rth(j-a) = 500 K/W (junction-to-ambient in free air), enabling reliable operation up to 150 °C junction temperature when mounted on standard FR4 PCB with 70 μm copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.47 V to 13.96 V @ IZ = 5 mA - tight ±2 % tolerance ensures predictable clamping in precision reference circuits |
| Differential Resistance rdif | 10 Ω typ @ IZ = 5 mA - low impedance maintains stable output voltage under small load variations |
| Temperature Coefficient SZ | −2.0 mV/K @ IZ = 5 mA - negative drift compensates for typical PCB thermal gradients in sensor interfaces |
| Reverse Current IR | 0.1 μA max @ VR = 10 V - ultra-low leakage preserves battery life in always-on monitoring nodes |
| Total Power Dissipation Ptot | 250 mW @ Tamb = 25 °C - sufficient for low-current biasing and signal-level regulation without heatsinking |
| Non-repetitive Peak Power PZSM | 40 W @ tp = 100 μs - enables transient surge suppression in ESD-critical I/O protection paths |
| Forward Voltage VF | 0.9 V max @ IF = 10 mA - low conduction loss supports bidirectional clamp configurations |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch); thermally optimized for reflow soldering with cathode tab as primary heat path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connects to lower-potential node in reverse-biased Zener configuration; carries forward current during fault conditions |
| 2 | Not Connected (n.c.) | Internally unconnected terminal; must remain floating-no PCB trace or pad required |
| 3 | Cathode (K) | Primary reverse-bias terminal and thermal interface; soldered directly to copper pour for optimal heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in 13 V reference designs without recalibration or resistor trimming |
| Hard breakdown knee | Ensures rapid transition from blocking to conduction mode-critical for accurate overvoltage detection thresholds |
| 10 Ω typical dynamic impedance | Minimizes output voltage shift under ±1 mA load variation-supports stable biasing of op-amp input stages |
| Ultra-low 0.1 μA max leakage @ 10 V | Reduces quiescent current in battery-powered voltage monitors and wake-up circuitry |
| Rth(j-sp) = 330 K/W | Allows 150 °C junction operation with ≤100 mW sustained power on standard FR4-no thermal relief needed |
Applications
| Power Supply Reference | Overvoltage Protection |
|---|---|

IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference potential relative to ground. Use Value: ±2 % tolerance and −2.0 mV/K TC ensure <±1.5 % total error over −40 °C to +85 °C, eliminating need for external calibration. |

IC Role / Device Role / Timing Role: Shunt regulator absorbing surge energy during voltage spikes to protect downstream logic inputs. Use Value: 40 W non-repetitive peak power rating handles 100 μs surges without degradation, while 0.1 μA leakage avoids signal loading. |

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, 20 Ω typical rdif, 1 μA max IR @ 10 V | Higher voltage drift and leakage reduce accuracy in precision references | Select only where cost sensitivity outweighs regulation stability requirements |
| MMSZ4688 | ±5 % tolerance, 30 Ω typical rdif, 100 nA max IR @ 10 V, same SOT23 package | Lower leakage benefits ultra-low-power sleep modes but higher impedance degrades load regulation | Prefer for battery-backed memory retention circuits; avoid in active bias networks |
Compared with PZU84-B13R, BZX84-C13 trades tighter voltage control for lower unit cost, while MMSZ4688 prioritizes leakage reduction over dynamic impedance-making PZU84-B13R the optimal choice for applications demanding both precision and low-impedance regulation.

FAQ
What is the maximum continuous reverse power dissipation for PZU84-B13R at 85 °C ambient?
At 85 °C ambient, derated power is calculated using Rth(j-a) = 500 K/W: Ptot = (Tj(max) − Tamb) / Rth(j-a) = (150 − 85) / 500 = 130 mW. This ensures safe long-term operation without exceeding 150 °C junction temperature under natural convection.
Can PZU84-B13R be used in bidirectional TVS configurations?
No-PZU84-B13R is a unidirectional Zener diode with anode and cathode terminals; its 0.9 V forward voltage and lack of symmetric avalanche characteristics make it unsuitable for bidirectional transient suppression. Use dedicated bidirectional TVS arrays like PESD5V0S1BA for such applications.
How does the "B" suffix in PZU84-B13R affect its electrical behavior versus "C" variants?
The "B" suffix denotes ±2 % Zener voltage tolerance and hard breakdown knee, whereas "C" variants offer approximately ±5 % tolerance with intentionally higher leakage for noise reduction. PZU84-B13R thus provides superior voltage accuracy and sharper regulation onset, critical for reference applications.
Is the not-connected (n.c.) pin in SOT23 package electrically isolated or internally tied?
Pin 2 is fully unconnected-no internal bond wire or silicon connection exists. It must remain unpopulated on PCB layouts; routing traces or applying solder paste to this pad risks mechanical stress and potential shorting to adjacent terminals during reflow.
