Product details
Overview
PDZ10BF 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 10.0 V (9.77–10.21 V at IZ = 5 mA), ±2 % tolerance, 60 Ω maximum differential resistance at 5 mA, and 0.1 µA maximum reverse leakage at 7.0 V.
For engineers reviewing the PDZ10BF datasheet, PDZ10BF pinout, PDZ10BF application, or PDZ10BF equivalent, this device is selected for precision clamping, reference voltage generation, and overvoltage protection in consumer power rails, sensor biasing circuits, and low-current analog signal conditioning where tight voltage stability and small footprint are critical.
Technical Context
The PDZ10BF operates as a two-terminal voltage reference diode with hard breakdown knee and low dynamic impedance - optimized for stable regulation at low test currents (IZ = 0.5 mA to 5 mA). Its temperature coefficient is +6.4 mV/K at IZ = 5 mA, indicating positive drift with junction temperature rise.
Thermal performance is defined by Rth(j-sp) = 130 K/W (junction-to-solder point) and Rth(j-a) = 340 K/W (junction-to-ambient on FR4 PCB), supporting reliable operation up to Tj = +150 °C and Tstg = −65 to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 9.77–10.21 V at IZ = 5 mA - defines precise clamping threshold for 10 V rail stabilization |
| Differential Resistance rdif | ≤ 60 Ω at IZ = 5 mA - ensures minimal output voltage variation under load current shifts |
| Reverse Leakage IR | ≤ 0.1 µA at VR = 7.0 V - enables ultra-low standby power loss in battery-backed circuits |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - supports efficient forward conduction during transient polarity reversal |
| Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C - sets thermal design boundary for PCB copper area and derating curve use |
| Capacitance Cd | 110 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and AC coupling integrity |
Pinout & Package
PDZ10BF is housed in a miniature SOD323 (SC-76) surface-mount plastic package measuring 1.8 × 1.35 × 0.95 mm, with cathode marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; voltage reference anode is tied to ground or lower potential |
| 2 (A) | Anode | Connected to ground or return path; reverse-biased operation requires anode at lower potential than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 60 Ω max at 5 mA - maintains tight regulation across small current variations in feedback loops |
| Hard breakdown knee | Sharp, non-gradual Zener onset - improves accuracy in precision reference and clamp applications |
| Ultra-low leakage | 0.1 µA max at 7 V - preserves battery life and avoids signal path loading in high-impedance nodes |
| SOD323 footprint | 1.8 × 1.35 mm outline - enables placement in dense layouts including wearables and IoT sensor modules |
Applications
| USB Port Overvoltage Clamp | Microcontroller Reset Circuit Reference |
|---|---|
Use Scenario: Protects 5 V USB data/power lines from ESD-induced transients exceeding 10 V. IC Role / Device Role / Timing Role: Zener clamps surge voltage to safe level before it reaches downstream USB PHY or LDO. Use Value: Limits peak excursion to ≤10.21 V with <60 Ω impedance, preventing latch-up or gate oxide damage. |
Use Scenario: Provides stable 10 V reference for RC-based reset timing in MCU power-up sequencing. IC Role / Device Role / Timing Role: Acts as precision voltage threshold detector triggering reset release when VCC exceeds 10 V. Use Value: ±2 % tolerance and +6.4 mV/K TC ensure predictable release timing across −40 to +85 °C ambient. |
| Industrial Sensor Biasing | Low-Power Analog Front-End Clamp |
Use Scenario: Supplies stable bias voltage to bridge-based pressure sensors operating from 12 V supply rails. IC Role / Device Role / Timing Role: Regulates excitation voltage to sensor Wheatstone bridge, rejecting supply ripple. Use Value: 400 mW rating and 130 K/W junction-to-solder thermal resistance allow continuous operation on standard FR4. |
Use Scenario: Clamps input signals to ADC front-end to prevent saturation from transient spikes. IC Role / Device Role / Timing Role: Shunts excess voltage above 10.21 V to ground via low-impedance Zener path. Use Value: 110 pF capacitance minimizes signal distortion below 10 MHz; 0.1 µA leakage avoids DC offset error. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C10 | Same 10 V nominal, but ±5 % tolerance and higher rdif (100 Ω); SOD523 package (smaller, 1.2 × 0.8 mm) | Less precise regulation; better suited for non-critical clamping where size is paramount | Select when board space is tighter than voltage accuracy requirements |
| MMSZ5240B | 10 V nominal, ±5 % tolerance, 17 Ω rdif, 500 mW Ptot; SOD-123 package (larger, 2.7 × 1.6 mm) | Lower impedance but larger footprint and looser tolerance; higher power handling | Select when lower dynamic impedance is prioritized over size and tolerance |
Compared with BZX584C10 and MMSZ5240B, PDZ10BF delivers superior voltage accuracy (±2 % vs ±5 %) and moderate impedance (60 Ω) in the smallest viable SOD323 package - ideal for cost-sensitive, space-constrained designs requiring repeatable 10 V regulation without thermal derating penalties.

FAQ
What is the maximum reverse current the PDZ10BF can handle in non-repetitive surge conditions?
The PDZ10BF supports a non-repetitive peak reverse current (IZSM) of 3.5 A at tp = 100 µs and Tamb = 25 °C, verified per IEC 60134 limiting values. This rating applies only to short-duration transients and must be paired with appropriate series impedance to limit energy dissipation within the 400 mW total power limit.
Does the PDZ10BF have a specified junction-to-case thermal resistance?
No - the datasheet specifies Rth(j-sp) = 130 K/W (junction-to-solder point) and Rth(j-a) = 340 K/W (junction-to-ambient on FR4 PCB), but does not define a junction-to-case value. Thermal design must rely on solder-point or ambient metrics, using the provided derating curve for elevated ambient temperatures.
Can PDZ10BF be used in forward-biased mode as a standard rectifier diode?
Yes - its forward voltage is ≤0.9 V at 10 mA and ≤1.1 V at 100 mA, making it usable as a low-current signal diode. However, its 200 mA continuous forward current rating and lack of fast-recovery optimization mean it is not recommended for switching or high-frequency rectification.
How does the +6.4 mV/K temperature coefficient affect long-term voltage reference stability?
A +6.4 mV/K coefficient means VZ increases ~64 mV over a 10 °C rise - e.g., from 10.00 V at 25 °C to ~10.06 V at 35 °C. For applications requiring <0.1 % drift, ambient temperature control or compensation circuitry is necessary; unregulated environments may see >±0.3 % variation across −40 to +85 °C.
