Product details
Overview
PDZ5.6B,115 from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in space-constrained SMD applications, with a nominal Zener voltage of 5.6 V at 5 mA, dynamic impedance of 100 Ω, reverse current ≤1 μA at 4.5 V, temperature coefficient of +1.9 mV/K, and total power dissipation up to 400 mW in SOD323 package - used in precision reference and overvoltage protection circuits for microcontroller I/O rail clamping.
For engineers reviewing the PDZ5.6B,115 datasheet, PDZ5.6B,115 pinout, PDZ5.6B,115 application, or PDZ5.6B,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), low leakage (<1 μA @ VR = 4.5 V), hard breakdown knee, thermal resistance (Rth(j-a) = 340 K/W), and compatibility with reflow/wave soldering per IPC-7095 standards.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with tightly controlled VZ stability across temperature (SZ = +1.9 mV/K at IZ = 5 mA) and exhibits low differential resistance (rdif = 100 Ω at IZ = 5 mA), enabling stable reference generation under varying load conditions. Its hard breakdown knee ensures predictable turn-on behavior without soft saturation.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it delivers specified performance only when mounted using standard SOD323 footprint (Fig. 9/10) and derated above Tamb = 25 °C per Fig. 1 - Ptot drops linearly to zero at 150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.48 V to 5.73 V at IZ = 5 mA - defines regulated output voltage with ±2 % tolerance for stable reference design |
| Differential Resistance rdif | 100 Ω at IZ = 5 mA - determines output impedance and voltage regulation sensitivity to current variation |
| Reverse Current IR | ≤1 μA at VR = 4.5 V - ensures minimal standby power loss and high off-state blocking integrity |
| Temperature Coefficient SZ | +1.9 mV/K at IZ = 5 mA - enables predictable VZ drift compensation in temperature-varying environments |
| Total Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous power handling before thermal derating applies |
| Forward Voltage VF | 0.9 V at IF = 10 mA - defines forward conduction threshold for bidirectional clamp or ESD protection use cases |
| Junction-to-Ambient Rth(j-a) | 340 K/W - quantifies thermal path efficiency; requires PCB copper area management to avoid junction overheating |
Pinout & Package
PDZ5.6B,115 is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.8 mm × 1.35 mm × 0.95 mm (L × W × H), with cathode identified by a marking bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode-to-cathode voltage establishes Zener breakdown |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes current path during regulation or clamping |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 100 Ω at 5 mA - improves regulation accuracy under dynamic load transients |
| Hard breakdown knee | Sharp V-I transition at rated VZ - eliminates ambiguity in turn-on threshold for precision clamping |
| Very low leakage current | ≤1 μA at 4.5 V - minimizes quiescent current in battery-powered or high-impedance reference circuits |
| Stable temperature coefficient | +1.9 mV/K - supports predictable VZ drift modeling for compensated reference designs |
| SOD323 footprint compatibility | Standard IPC-7095-compliant land pattern - ensures manufacturability with mainstream reflow processes |
Applications
| Microcontroller I/O Protection | Low-Power Reference Source |

Use Scenario: Clamping 3.3 V or 5 V MCU GPIO lines against ESD or transient overvoltage. IC Role / Device Role / Timing Role: Bidirectional voltage limiter placed between I/O pin and ground, leveraging Zener reverse breakdown and forward conduction. Use Value: Limits pin voltage to ≤5.73 V (reverse) and ≥−0.9 V (forward), preventing latch-up and oxide damage while drawing <1 μA leakage in normal operation. |
Use Scenario: Generating stable 5.6 V reference for ADC biasing or sensor excitation in portable instrumentation. IC Role / Device Role / Timing Role: Shunt reference element operating at 5 mA, buffered via op-amp follower for low-noise output. Use Value: Delivers ±2 % initial accuracy and +1.9 mV/K drift, enabling sub-0.5 % total error over 0–70 °C with simple compensation. |
| Power Rail Clamp | Signal-Level Translation |
|
Use Scenario: Protecting 5 V logic rails from supply overshoot during hot-swap or load-dump events. IC Role / Device Role / Timing Role: Passive shunt regulator connected between rail and ground, sinking excess current above VZ. Use Value: Absorbs up to 400 mW continuously (derated above 25 °C), limiting rail excursion to 5.73 V with <100 Ω output impedance. |
Use Scenario: Level-shifting 3.3 V logic signals to interface with 5 V peripherals using passive Zener biasing. IC Role / Device Role / Timing Role: Cathode tied to 5 V rail, anode driving signal node - establishes ~5.6 V clamped high level. Use Value: Provides deterministic high-level translation with fast response (ns-scale recovery), no active components required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V6 | VZ = 5.6 V ±5 %, rdif = 90 Ω, IR = 0.1 μA @ 4.5 V, SOD523 package (smaller, higher Rth) | Lower leakage but tighter thermal limits due to smaller package; less suitable for sustained >200 mW dissipation | Prefer for ultra-low-leakage, low-duty-cycle clamping where board space is critical |
| MMSZ5232BT1G | VZ = 5.6 V ±5 %, rdif = 17 Ω, IR = 1 μA @ 4.5 V, SOD123 package (larger, lower Rth) | Lower dynamic impedance and better thermal performance (Rth(j-a) ≈ 270 K/W), but larger footprint | Prefer for high-stability reference designs requiring <20 Ω output impedance and higher power margin |
Compared with BZX584-C5V6 and MMSZ5232BT1G, PDZ5.6B,115 offers balanced trade-offs: tighter VZ tolerance (±2 % vs ±5 %), moderate rdif (100 Ω), and proven manufacturability in SOD323 - making it optimal for cost-sensitive, medium-accuracy regulation where footprint and process compatibility are prioritized.

FAQ
What is the maximum continuous reverse current the PDZ5.6B,115 can sustain without degradation?
The PDZ5.6B,115 has no defined maximum continuous reverse current rating; its safe operating limit is governed by power dissipation. At 25 °C ambient on FR4 PCB, it sustains up to 71.4 mA (400 mW ÷ 5.6 V) continuously before exceeding Ptot. Derating applies above 25 °C per Fig. 1 - at 85 °C ambient, max IZ drops to ~235 mA × (400 mW / 340 K/W × (150 − 85)) ≈ 42 mA.
Does the PDZ5.6B,115 support wave soldering, and what are the recommended footprint dimensions?
Yes, PDZ5.6B,115 supports wave soldering using the footprint in Fig. 10: 1.2 mm × 2.75 mm solder lands, 0.5 mm solder resist opening per pad, and preferred transport direction aligned with the 2.75 mm dimension. Thermal relief and copper balancing must follow IPC-7095 Class 2 guidelines to prevent tombstoning or voiding.
How does the +1.9 mV/K temperature coefficient affect long-term reference stability?
A +1.9 mV/K coefficient means VZ increases by 1.9 mV per °C rise in junction temperature. Over a 70 °C range (25–95 °C), this causes ~133 mV drift (5.6 V × 0.0238). For <0.1 % stability, external compensation (e.g., NTC thermistor network or op-amp correction) is required - uncorrected, it contributes ±0.24 % error across that range.
Is the PDZ5.6B,115 suitable for automotive applications?
No - PDZ5.6B,115 is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" and excludes AEC-Q200 stress testing. It lacks qualification for temperature cycling, humidity bias, or mechanical shock per automotive requirements and carries no guaranteed PPAP documentation or extended-lifetime reliability data.
