Product details
Overview
PDZ36B,115 from Nexperia is a single Zener diode designed for low-power voltage regulation in surface-mounted applications, with a nominal Zener voltage of 36 V (min 35.07 V, max 36.87 V at IZ = 5 mA), ±2 % tolerance, 60 Ω maximum differential resistance at 5 mA, and 0.05 μA reverse current at VR = 27 V - used in power supply reference and overvoltage protection circuits.
For engineers reviewing the PDZ36B,115 datasheet, PDZ36B,115 pinout, PDZ36B,115 application, or PDZ36B,115 equivalent, this device serves as a precision, low-leakage, SOD323-packaged Zener regulator suitable for compact DC-DC feedback networks, voltage clamping in sensor interfaces, and rail stabilization in portable electronics where thermal resistance (Rth(j-a) = 340 K/W) and small-footprint reliability are critical.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its hard breakdown knee and low dynamic impedance (≤60 Ω at 5 mA) ensure predictable regulation even at low bias currents, while the −33.0 mV/K temperature coefficient at 5 mA enables predictable drift compensation in mid-to-high-voltage references.
Designed for FR4 PCB mounting with standard SOD323 footprint, it delivers 400 mW total power dissipation at Tamb ≤ 25 °C and derates linearly above that point. The cathode-marked package supports unidirectional clamping and bidirectional ESD suppression when paired with complementary devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 35.07 V to 36.87 V at IZ = 5 mA - defines precise regulation threshold for 36 V nominal rail stabilization |
| Differential Resistance (rdif) | ≤60 Ω at IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Current (IR) | ≤0.05 μA at VR = 27 V - enables ultra-low standby power loss in battery-backed circuits |
| Power Dissipation (Ptot) | 400 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous clamp energy before thermal shutdown |
| Thermal Resistance (Rth(j-a)) | 340 K/W - determines junction temperature rise per watt, critical for reliability in enclosed designs |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - defines conduction loss when used in series forward-biased configurations |
| Temperature Coefficient (SZ) | −33.0 mV/K at IZ = 5 mA - quantifies voltage drift per degree, enabling thermal error budgeting |
Pinout & Package
PDZ36B,115 is housed in a SOD323 (SC-76) surface-mount plastic package measuring 1.8 mm × 1.35 mm × 0.95 mm, with cathode indicated by a marking bar on the body. The two-terminal configuration supports direct integration into high-density PCB layouts without through-hole routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to regulated output node; reverse-biased during Zener operation; carries clamped current to ground or lower potential |
| 2 | Anode (A) | Connected to reference or input rail; establishes polarity for breakdown conduction and defines current direction in regulation path |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 60 Ω max at 5 mA - maintains tight voltage regulation under dynamic load changes |
| Hard breakdown knee | Sharp, non-gradual transition into conduction - improves accuracy in precision reference applications |
| Ultra-low leakage | 0.05 μA max at 27 V reverse bias - minimizes quiescent current in always-on monitoring circuits |
| SOD323 footprint compatibility | Standardized 1.8 mm × 1.35 mm outline - enables automated placement and reflow soldering on high-volume PCBs |
| ±2 % voltage tolerance | Tight initial calibration - reduces need for post-assembly trimming in production-grade voltage references |
Applications
| Power Supply Feedback Reference | Sensor Signal Clamping |
|---|---|
|

| Microcontroller Reset Circuit | Battery Voltage Monitor Threshold |
|
Use Scenario: Generating a clean reset signal when main 36 V rail drops below safe operating level. IC Role / Device Role / Timing Role: Zener + resistor network pulls reset line low when VIN falls below 35.07 V, ensuring deterministic brown-out detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B36,115 | Same SOD323 package, identical 36 V nominal rating, but higher typical rdif (70 Ω vs. 60 Ω) and wider tolerance (±5 % vs. ±2 %) | Acceptable where cost sensitivity outweighs regulation precision; less suitable for feedback loops demanding tight loop gain | Select when BOM cost reduction is prioritized over voltage stability under load variation |
| MMSZ5267BT1G | Same 36 V nominal, SOD-123 package (larger footprint), 100 Ω rdif, 0.1 μA IR at 27 V - higher leakage and lower regulation fidelity | Compatible only if board layout allows SOD-123 pad revision; not drop-in due to different land pattern and thermal profile | Choose only if legacy SOD-123 design reuse is mandatory and 0.05 μA leakage is non-critical |
Compared with BZX384-B36,115 and MMSZ5267BT1G, PDZ36B,115 offers superior regulation precision (±2 %), lower dynamic impedance (60 Ω), and lower leakage (0.05 μA), making it optimal for high-accuracy feedback and low-power sensing - whereas alternatives trade performance for cost or footprint compatibility.

FAQ
What is the maximum reverse current specification for PDZ36B,115 at 27 V?
The maximum reverse current (IR) for PDZ36B,115 is 0.05 μA at VR = 27 V and Tj = 25 °C. This ultra-low leakage ensures minimal power loss in always-on monitoring circuits and preserves battery life in portable 36 V systems.
Can PDZ36B,115 be used in parallel for higher power handling?
No - PDZ36B,115 is not designed for parallel operation due to mismatch in Zener voltage and temperature coefficient between units, which causes current hogging and thermal runaway. For higher power, use a single higher-rated Zener or a dedicated voltage reference IC.
Is the SOD323 package suitable for reflow soldering?
Yes - PDZ36B,115's SOD323 package is qualified for lead-free reflow soldering per J-STD-020. Recommended profile includes peak temperature ≤260 °C, time above liquidus 60–150 s, and ramp rates compliant with IPC-J-STD-020 Class 3 guidelines.
What is the thermal resistance from junction to ambient for PDZ36B,115?
The junction-to-ambient thermal resistance (Rth(j-a)) is 340 K/W when mounted on a standard FR4 PCB with single-sided copper, tin-plated, and the recommended footprint. This value assumes free-air convection and defines the temperature rise per watt of dissipated power.
