Product details
Overview
PDZ6.2BF from Nexperia is a single Zener diode designed for low-power voltage regulation in space-constrained SMD applications, with a nominal Zener voltage of 6.2 V at 5 mA, ±2 % tolerance, 80 Ω maximum differential resistance at 5 mA, 0.5 μA maximum reverse current at 4.7 V, and 3.0 mV/K temperature coefficient. It operates in general-purpose power supply rail clamping and reference circuits.
For engineers reviewing the PDZ6.2BF datasheet, PDZ6.2BF pinout, PDZ6.2BF application, or PDZ6.2BF equivalent, this device is selected for precision low-current voltage referencing, ESD-robust signal-level clamping, and compact board-level regulation where thermal resistance (Rth(j-a) = 340 K/W) and SOD323 footprint compatibility are critical.
Technical Context
The PDZ6.2BF implements a silicon planar Zener structure optimized for sharp breakdown knee and stable regulation at low test currents (IZ = 5 mA), enabling accurate voltage references in battery-powered and low-quiescent systems. Its 6.06 V to 6.33 V working voltage range ensures tight regulation across production lots.
Designed for surface-mount use on FR4 PCBs with standard solder footprints, it delivers 400 mW total power dissipation at Tamb ≤ 25 °C and maintains reliable operation up to 150 °C junction temperature, with thermal resistance from junction to ambient rated at 340 K/W under defined mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.06 V to 6.33 V at IZ = 5 mA - defines precise clamping threshold for 5 V–6 V rail protection |
| Differential Resistance (rdif) | ≤ 80 Ω at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Reverse Current (IR) | ≤ 0.5 μA at VR = 4.7 V - guarantees low leakage in high-impedance bias networks |
| Temperature Coefficient (SZ) | +2.7 mV/K at IZ = 5 mA - enables predictable drift compensation in temperature-sensitive references |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - supports bidirectional transient suppression when used with series resistor |
| Total Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous clamping energy without derating |
| Junction-to-Ambient Thermal Resistance | 340 K/W - determines required board copper area and airflow for thermal management |
Pinout & Package
PDZ6.2BF is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.8 mm × 1.35 mm × 0.95 mm, with cathode indicated by a marking bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; reverse-biased during Zener operation; marking bar identifies this terminal |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes conduction path during breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance at low current | 80 Ω max at 5 mA - improves regulation accuracy in micro-power sensor biasing |
| Hard breakdown knee | Sharp transition from blocking to conduction - reduces ambiguity in threshold detection circuits |
| Very low leakage current | 0.5 μA max at 4.7 V - preserves signal integrity in high-impedance analog monitoring paths |
| SOD323 footprint compatibility | Standardized 1.8 mm × 1.35 mm land pattern per JEDEC SC-76 - enables automated placement and reflow |
| ±2 % voltage tolerance | Tight initial calibration - eliminates need for post-assembly trimming in cost-sensitive consumer designs |
Applications
| USB Port Overvoltage Protection | Microcontroller I/O Clamp Circuit |
|---|---|
Use Scenario: Clamping 5 V USB data lines against ESD transients and accidental 12 V misconnection. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to shunt excess voltage to ground before IC damage occurs. Use Value: 6.2 V breakdown threshold provides 1.2 V margin above 5 V USB VBUS while staying below typical MCU I/O absolute maximum rating (6.5 V). |
Use Scenario: Protecting GPIO pins of ARM Cortex-M0+ microcontrollers from overvoltage during hot-plug or level-shifting events. IC Role / Device Role / Timing Role: Passive clamp limiting input voltage to safe levels without affecting normal 0–3.3 V logic swing. Use Value: 0.5 μA leakage at 4.7 V prevents measurable loading on high-impedance input buffers during normal operation. |
| Low-Power Sensor Reference | Industrial 4–20 mA Loop Clamp |
Use Scenario: Providing stable 6.2 V reference for ADC biasing in battery-operated environmental sensors. IC Role / Device Role / Timing Role: Precision Zener acting as two-terminal voltage reference in ultra-low-current (<100 μA) bias network. Use Value: +2.7 mV/K temperature coefficient allows predictable drift modeling for software-based compensation in firmware. |
Use Scenario: Limiting loop voltage in 4–20 mA current transmitters to prevent damage during open-circuit faults. IC Role / Device Role / Timing Role: Fail-safe shunt element clamping transmitter output to 6.2 V when load impedance exceeds design limit. Use Value: 400 mW power rating sustains 6.2 V × 64 mA = 397 mW during sustained open-circuit condition without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2 | Same 6.2 V nominal Zener voltage, but higher rdif (100 Ω max), higher leakage (1.0 μA), and SOD323 package. | Less precise regulation at low current; suitable only where tighter tolerance is not required. | Select when cost is prioritized over regulation stability in non-critical clamping. |
| MMSZ4687 | 6.2 V nominal, but ±5 % tolerance, 100 Ω rdif, and SOD123 package (larger footprint). | Looser voltage spec and larger board area requirement; lacks hard knee behavior. | Choose only if SOD123 layout is already fixed and ±5 % tolerance is acceptable. |
Compared with BZX384-B6V2 and MMSZ4687, PDZ6.2BF offers superior regulation precision (±2 % vs ±5 %), lower dynamic impedance (80 Ω vs ≥100 Ω), and lower leakage (0.5 μA vs ≥1.0 μA), making it optimal for high-fidelity reference and low-power clamping where voltage accuracy and thermal efficiency are design-critical.

FAQ
What is the maximum continuous reverse current the PDZ6.2BF can handle without degradation?
The PDZ6.2BF is rated for a maximum non-repetitive peak reverse current (IZSM) of 5.5 A at tp = 100 μs, but its continuous Zener current is limited by power dissipation: at 25 °C ambient, IZ must stay ≤ 64.5 mA to maintain Ptot ≤ 400 mW (6.2 V × 64.5 mA ≈ 400 mW). Derating applies above 25 °C per the published power curve.
How does the +2.7 mV/K temperature coefficient affect circuit performance over –40 °C to +85 °C?
Over a 125 °C range, the Zener voltage shifts by approximately +337 mV (2.7 mV/K × 125 K), resulting in a VZ span of ~6.06 V to ~6.40 V. This drift is linear and predictable, enabling firmware-based compensation in precision reference applications where absolute accuracy is less critical than monotonic behavior.
Can PDZ6.2BF be used in bidirectional TVS configurations?
No - PDZ6.2BF is a unidirectional Zener diode with anode and cathode terminals; it conducts only in reverse breakdown. For bidirectional transient suppression, two PDZ6.2BF devices must be connected anode-to-anode (back-to-back), or a dedicated bidirectional TVS like PESD5V0S1BA should be selected instead.
Is the SOD323 footprint compatible with automated optical inspection (AOI) systems?
Yes - the SOD323 package has standardized dimensions (1.8 mm × 1.35 mm) and visible cathode marking bar, meeting IPC-7351B Class L requirements for AOI detectability. The recommended reflow footprint (Fig. 9) provides adequate solder paste volume and contrast for reliable machine vision verification of placement and solder joint quality.
