Product details
Overview
BZT52-C36J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 36 V nominal Zener voltage at 2 mA test current, 250 Ω maximum differential resistance, and 590 mW total power dissipation. It provides precision voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the BZT52-C36J datasheet, BZT52-C36J pinout, BZT52-C36J application, or BZT52-C36J equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (210 K/W junction-to-solder-point), reverse leakage at 28.8 V (≤0.1 μA), and SOD123 footprint compatibility with automated SMT assembly.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage across load variations by conducting reverse current above its specified Zener breakdown threshold. Its temperature coefficient of +12.6 mV/K at 5 mA enables predictable drift compensation in bias networks.
The SOD123 package delivers low thermal resistance (210 K/W to solder point) and supports reflow-only mounting per JEDEC J-STD-020. Cathode identification is marked by a visible band on the body, aligning with Pin 1 in the standardized 2-pin anode–cathode configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines regulation setpoint with ±5 % tolerance for mid-range precision applications |
| Differential Resistance (rdif) | 250 Ω max at IZ = 2 mA - determines regulation stiffness and output impedance under dynamic load changes |
| Reverse Current (IR) | ≤0.1 μA at VR = 28.8 V - ensures minimal quiescent power loss in standby or high-impedance sensing nodes |
| Total Power Dissipation (Ptot) | 590 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling with standard copper pad layout |
| Junction-to-Solder-Point Rth | 210 K/W - enables thermal design margin for board-level power derating up to 150 °C junction temperature |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction drop when used in series polarity or ESD clamp configurations |
| Non-repetitive Peak Power | 40 W at tp = 100 μs - supports transient surge suppression in low-duty-cycle protection circuits |
Pinout & Package
SOD123 surface-mount plastic package: 2.80 mm × 1.70 mm body, 0.70 mm lead pitch, cathode marked by molded band. Designed for reflow soldering only; footprint requires 0.81 mm × 2.36 mm Cu pad per terminal with 0.91 mm solder mask opening.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; carries reverse breakdown current during regulation; marked by physical band |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes shunt path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-optimized regulation where tighter tolerance is unnecessary, e.g., non-critical biasing or coarse reference generation |
| Low differential resistance (250 Ω) | Maintains <±100 mV output deviation across ±1 mA load current variation, improving regulation accuracy in variable-current sinks |
| 150 °C maximum junction temperature | Supports operation in industrial ambient environments (−55 °C to +150 °C) without derating below 100 °C ambient |
| 210 K/W junction-to-solder-point thermal resistance | Allows direct thermal coupling to PCB copper, enabling reliable power handling without heatsinks in space-constrained layouts |
| Reflow-only soldering compliance | Eliminates wave soldering risk of thermal damage; compatible with standard J-STD-020 profile for high-yield SMT manufacturing |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5265BLT1G | 36 V nominal, ±5 %, 200 mW Ptot, SOT-23 package | Lower power rating and different footprint; requires PCB redesign | Select when board space allows SOT-23 and thermal load stays below 200 mW |
| Vishay BZX84-C36 | 36 V nominal, ±5 %, 300 mW Ptot, SOT-23 package | Higher thermal resistance (350 K/W j-a); unsuitable for >150 mW continuous operation | Choose only for low-duty-cycle or pulsed applications where average power remains <100 mW |
Compared with BZT52-C36J, the MMBZ5265BLT1G offers identical regulation but reduced thermal capability and incompatible packaging, while the BZX84-C36 sacrifices 47 % of continuous power handling and doubles junction-to-ambient thermal resistance-making both unsuitable as drop-in replacements in SOD123-constrained, 500+ mW designs.

FAQ
What is the maximum continuous reverse current the BZT52-C36J can sustain at 25 °C ambient?
The device sustains up to 16.4 mA continuous reverse current at 25 °C ambient, calculated from Ptot = 590 mW and VZ = 36 V (590 mW ÷ 36 V ≈ 16.4 mA). Derating begins above 25 °C per the 210 K/W junction-to-solder-point thermal resistance curve.
Does the BZT52-C36J meet automotive AEC-Q200 requirements?
No. The BZT52-C36J is explicitly designated as non-automotive qualified per Nexperia's revision history (v.2, October 2025), which states C-series parts are excluded from automotive qualification. For automotive use, Nexperia recommends its -Q qualified alternatives such as PZTA42-Q.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a typical +12.6 mV/K coefficient at 5 mA, the Zener voltage shifts +1.89 V across 150 K ΔT (−40 °C to +110 °C junction), resulting in ~5.3 % full-scale drift. This is mitigated in practice by operating at lower currents or pairing with complementary NTC elements in precision references.
Can the BZT52-C36J be used in parallel for higher power handling?
No. Parallel connection is not recommended due to mismatched Zener voltages and thermal runaway risk. The 34–38 V tolerance range and positive temperature coefficient cause current hogging in one device, leading to premature failure. Use a single higher-rated device or active regulation instead.
