Product details

Overview

PDZ10B,115 from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in surface-mounted applications, with a nominal Zener voltage of 10.0 V (9.77–10.21 V at I_Z = 5 mA), ±2 % tolerance, 60 Ω maximum differential resistance at 5 mA, and 0.1 µA maximum reverse leakage at 7.0 V. It operates in the SOD323 (SC-76) package and supports general-purpose clamping and reference functions in power supply feedback paths and overvoltage protection circuits.

For engineers reviewing the PDZ10B,115 datasheet, PDZ10B,115 pinout, PDZ10B,115 application, or PDZ10B,115 equivalent, key selection criteria include Zener voltage accuracy, low dynamic impedance at low bias currents, thermal resistance (R_th(j-a) = 340 K/W), cathode-marked polarity, and compatibility with reflow/wave soldering footprints per JEDEC SC-76 standards.

Technical Context

This Zener diode employs planar epitaxial construction to achieve hard breakdown knee characteristics and stable regulation under low-current conditions (I_Z ≥ 0.5 mA). Its temperature coefficient of +6.4 mV/K at 5 mA enables predictable drift behavior in ambient-temperature-varying environments.

The device is rated for 400 mW total power dissipation on FR4 PCB with single-sided copper, and exhibits forward voltage ≤ 0.9 V at 10 mA and ≤ 1.1 V at 100 mA - supporting bidirectional use as both regulator and clamp in low-energy signal conditioning stages.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	9.77–10.21 V at I_Z = 5 mA - defines precise regulation threshold for feedback or clamp circuits
Differential Resistance (r_diff)	≤ 60 Ω at I_Z = 5 mA - ensures minimal output voltage variation under load current changes
Reverse Leakage (I_R)	≤ 0.1 µA at V_R = 7.0 V - enables ultra-low standby power loss in battery-backed systems
Power Dissipation (P_tot)	400 mW at T_amb = 25 °C - sets maximum continuous operating envelope on standard FR4 PCB
Thermal Resistance (R_th(j-a))	340 K/W - determines junction-to-ambient temperature rise per watt, critical for derating above 25 °C
Forward Voltage (V_F)	≤ 0.9 V at I_F = 10 mA - supports use as low-loss series diode in polarity protection or OR-ing circuits
Package	SOD323 (SC-76) - 1.35 × 1.75 mm footprint optimized for high-density SMT assembly and automated optical inspection

Pinout & Package

SOD323 (SC-76) plastic surface-mounted package with 2 leads; cathode identified by marking bar on top surface.

Pin/Terminal	Circuit Role	Design Meaning
1	Cathode (K)	Connected to regulated output node; accepts reverse-bias current during Zener conduction
2	Anode (A)	Connected to reference or ground potential; completes bias path for regulation

Key Features

Feature	Design Value
Hard breakdown knee	Enables sharp, repeatable turn-on at V_Z, reducing regulation hysteresis in precision references
Very low leakage (0.1 µA)	Minimizes quiescent current draw in always-on monitoring circuits and energy-harvesting nodes
Low dynamic impedance (60 Ω)	Maintains tight voltage stability across varying load currents in feedback loops and shunt regulators
JEDEC SC-76 compliant footprint	Ensures compatibility with industry-standard reflow profiles and pick-and-place equipment
±2 % voltage tolerance	Reduces need for post-assembly trimming in cost-sensitive consumer and industrial power supplies

Applications

Power Supply Feedback Reference

Overvoltage Clamp for Microcontroller I/O

Use Scenario: Used in the optocoupler feedback path of isolated AC/DC flyback converters to stabilize output voltage.

IC Role / Device Role / Timing Role: Zener reference element providing stable 10 V threshold to drive optocoupler LED current.

Use Value: Tight 9.77–10.21 V tolerance and low r_diff ensure <±1% output regulation across line/load variations.

Use Scenario: Placed between microcontroller GPIO pin and ground to limit input voltage during ESD events or bus faults.

IC Role / Device Role / Timing Role: Passive clamping diode conducting reverse current when V_IN exceeds 10.21 V.

Use Value: 0.1 µA leakage preserves high-impedance input state; 3.5 A non-repetitive surge rating absorbs transient energy without failure.

Low-Power Sensor Bias Reference

USB Port Voltage Limiter

Use Scenario: Supplies stable bias to analog sensor front-ends (e.g., thermistor bridges or RTD interfaces) in battery-powered IoT nodes.

IC Role / Device Role / Timing Role: Shunt reference generating fixed 10 V node for excitation or ADC reference scaling.

Use Value: +6.4 mV/K tempco allows predictable calibration offset compensation; 400 mW rating supports intermittent high-current sensor bursts.

Use Scenario: Connected across VBUS and GND in USB 2.0 peripheral designs to prevent overvoltage damage during hot-plug or charger mismatch.

IC Role / Device Role / Timing Role: Fast-acting crowbar element limiting VBUS to ≤10.21 V during fault conditions.

Use Value: Hard knee and 60 Ω r_diff ensure rapid conduction onset and minimal overshoot before TVS activation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX55C10	Through-hole DO-35 package; 10 V ±5 % tolerance; higher r_diff (up to 200 Ω)	Not suitable for high-density SMT layouts; less precise regulation due to wider tolerance	Select when legacy through-hole assembly or lower-cost prototyping is required
MMSZ5240B	SOD-123 package; same 10 V nominal rating but ±5 % tolerance; 170 Ω r_diff; 500 mW P_tot	Larger footprint than SOD323; higher power handling but looser voltage spec	Choose for higher surge robustness where board space permits and tighter V_Z tolerance is not critical

Compared with BZX55C10 and MMSZ5240B, PDZ10B,115 delivers superior voltage accuracy (±2 % vs ±5 %), lower dynamic impedance (60 Ω vs ≥170 Ω), and smallest footprint (SOD323), making it optimal for space-constrained, precision-regulated embedded power rails.

FAQ

What is the maximum continuous reverse current the PDZ10B,115 can sustain at 10 V?

The PDZ10B,115 is not rated for continuous reverse current at its Zener voltage; instead, it is characterized at I_Z = 5 mA for specification purposes. Its absolute maximum non-repetitive peak reverse current is 3.5 A (t_p = 100 µs), but steady-state operation must remain within the 400 mW power limit - corresponding to ~40 mA at 10 V on a thermally optimized PCB.

Does the PDZ10B,115 have AEC-Q200 qualification for automotive use?

No, the PDZ10B,115 is not AEC-Q200 qualified. Nexperia explicitly states in the datasheet that unless otherwise specified, PDZ-B series devices are non-automotive qualified and not tested to automotive reliability or temperature requirements. Use in automotive applications requires customer validation and carries no manufacturer warranty.

How does the +6.4 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

At I_Z = 5 mA, the +6.4 mV/K coefficient causes approximately ±1.0 V drift across a 155 °C range (−40 °C to +115 °C junction), meaning V_Z shifts from ~9.0 V to ~11.0 V. This must be accounted for in wide-temperature designs - e.g., by using temperature-compensated reference ICs or calibrating in-system.

Can PDZ10B,115 be used in place of a 10 V TL431 shunt regulator?

No - the PDZ10B,115 is a passive two-terminal Zener diode without internal amplification or adjustable reference capability. Unlike the TL431 (a 3-terminal programmable shunt regulator with 2.5 V reference and op-amp control), it cannot regulate precisely at currents below 0.5 mA nor support feedback loop compensation. It serves only as a fixed-voltage clamp or coarse reference.
