Product details
Overview
PDZ36BF from Nexperia is a single silicon 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 leakage at VR = 27 V. It operates in the SOD323 (SC-76) package and delivers stable reference performance in power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the PDZ36BF datasheet, PDZ36BF pinout, PDZ36BF application, or PDZ36BF equivalent, this device is selected for precision low-current voltage clamping, board-level ESD-tolerant biasing, and compact DC rail stabilization where thermal resistance to solder point (130 K/W) and low dynamic impedance are critical design factors.
Technical Context
The PDZ36BF functions as a two-terminal voltage reference diode operating in reverse breakdown mode, with hard-knee breakdown characteristics confirmed across its 5 mA test current. Its temperature coefficient is +33.0 mV/K (typical) at IZ = 5 mA, indicating positive drift behavior suitable for compensation in higher-voltage regulator topologies.
Thermal performance is defined for mounting on FR4 PCB with single-sided copper and standard footprint: Rth(j-sp) = 130 K/W and Rth(j-a) = 340 K/W. Power dissipation is derated linearly above 25 °C ambient, reaching zero at 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 35.07 V to 36.87 V at IZ = 5 mA - defines precise clamping threshold for 36 V rail protection |
| Differential Resistance rdif | ≤ 300 Ω at IZ = 5 mA - ensures minimal voltage shift under load variation in feedback networks |
| Reverse Leakage IR | ≤ 0.05 μA at VR = 27 V - enables ultra-low standby current in battery-backed circuits |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - supports use as polarity-sensitive clamp or series diode in dual-role designs |
| Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C - sets maximum continuous energy handling on standard FR4 layout |
| Thermal Resistance Rth(j-sp) | 130 K/W - determines junction-to-solder-point temperature rise under steady-state bias |
| Non-repetitive Peak Current IZSM | 0.8 A for tp = 100 μs - defines surge immunity capability for transient suppression |
Pinout & Package
PDZ36BF is housed in a plastic surface-mounted SOD323 (SC-76) 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 | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes bias path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance at low current | 300 Ω max at 5 mA enables tight voltage control in low-power feedback loops |
| Hard breakdown knee | Sharp transition into conduction improves regulation stability vs. soft-clamp alternatives |
| Small SOD323 footprint | 1.8 × 1.35 mm outline supports high-density PCB layouts in space-constrained modules |
| ±2 % voltage tolerance | Reduces need for post-production trimming in production-grade voltage reference designs |
| Low leakage current | 0.05 μA at 27 V allows use in microamp-level standby circuits without compromising hold-up time |

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-B36 | Same 36 V nominal Zener, but SOD323 package with ±5 % tolerance and higher rdif (500 Ω) | Acceptable for non-critical biasing where tighter regulation not required | Select when cost sensitivity outweighs regulation precision needs |
| MMSZ5267B | 36 V Zener in SOD-123; ±5 % tolerance, 1000 mW Ptot, higher thermal resistance (400 K/W) | Suitable for higher-power dissipation scenarios with less board space constraint | Choose when thermal margin > electrical precision is the primary design driver |
Compared with BZX384-B36 and MMSZ5267B, PDZ36BF offers superior voltage accuracy (±2 % vs. ±5 %), lower dynamic impedance (300 Ω vs. ≥500 Ω), and optimized thermal path (130 K/W) - making it preferred for precision feedback and low-leakage biasing in miniaturized industrial systems.

FAQ
What is the maximum continuous reverse current the PDZ36BF can sustain at 25 °C?
The PDZ36BF does not specify a maximum continuous reverse current rating; instead, its operation is governed by power dissipation limits. At 25 °C ambient, it sustains up to 400 mW total power, corresponding to approximately 11.1 mA at 36 V Zener voltage. Exceeding this current risks thermal runaway unless board-level cooling is enhanced beyond the standard FR4 footprint.
Does PDZ36BF have AEC-Q200 qualification for automotive use?
No, PDZ36BF is not AEC-Q200 qualified. The Nexperia datasheet explicitly states that PDZ-B series devices are non-automotive qualified products and are neither tested nor warranted for automotive applications, including engine control, ADAS, or infotainment systems requiring automotive-grade reliability and stress testing.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At IZ = 5 mA, PDZ36BF exhibits a typical temperature coefficient of +33.0 mV/K. Over a 165 °C range, this results in ~5.4 V total drift - meaning regulation shifts from ~33.5 V at −40 °C to ~38.9 V at +125 °C. System-level compensation or closed-loop feedback is required for stable reference across full industrial temperature range.
Can PDZ36BF be used in parallel for higher current handling?
No - Zener diodes must not be paralleled without individual ballasting resistors due to mismatched breakdown voltages. Even within ±2 % tolerance, unit-to-unit VZ variation causes current hogging, leading to thermal instability and premature failure. For higher current, select a single higher-power Zener or implement active regulation.
