Product details
Overview
BZT52H-B36,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD123F package, rated for 36 V nominal breakdown voltage at IZ = 2 mA, 250 mA maximum forward current, and 830 mW total power dissipation at Tamb ≤ 25 °C. It delivers stable reference voltage in low-power supply regulation and overvoltage protection circuits.
For engineers reviewing the BZT52H-B36,115 datasheet, BZT52H-B36,115 pinout, BZT52H-B36,115 application, or BZT52H-B36,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), thermal resistance (150 K/W junction-to-solder point), differential resistance (250 Ω max), reverse current (≤60 μA at VR = 28.8 V), and SOD123F surface-mount compatibility.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 36 V reference under regulated current conditions. Its temperature coefficient is +0.05 mV/K at IZ = 2 mA, indicating minimal voltage drift across operating temperature.
The device uses planar epitaxial construction with cathode-anode polarity clearly marked by a bar on the SOD123F body. It supports non-repetitive peak reverse current up to 0.8 A (tp = 100 μs) and exhibits 45 pF capacitance at 1 MHz and 0 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 35.3 V to 36.7 V at IZ = 2 mA - defines precise regulation threshold for feedback or clamping |
| Tolerance | ±2 % - ensures tight voltage control for precision reference applications |
| Differential Resistance (rdif) | ≤250 Ω - limits output impedance and improves load regulation stability |
| Reverse Current (IR) | ≤60 μA at VR = 28.8 V - guarantees low leakage before breakdown onset |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables low-loss forward conduction during transient events |
| Junction Temperature (Tj) | −65 °C to +150 °C - supports operation in industrial ambient environments |
Pinout & Package
SOD123F is a small-outline, flat-lead, surface-mounted plastic package measuring 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), optimized for automated reflow assembly and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Three tolerance options | ±1 %, ±2 %, and ≈±5 % - enables trade-off between precision and cost per application requirement |
| Wide voltage range | 2.4 V to 75 V (E24 series) - covers most common reference and clamp needs without redesign |
| Low thermal resistance | 150 K/W junction-to-solder point - improves power handling in compact layouts with limited copper area |
| Non-repetitive surge capability | 0.8 A peak reverse current (100 μs pulse) - withstands short-duration transients without degradation |
| Standardized marking | "E7" code per Table 4 - enables rapid visual identification and traceability on assembled boards |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
|
Use Scenario: Stabilizing feedback voltage in linear regulators or switching converter error amplifiers. IC Role / Device Role / Timing Role: Provides fixed 36 V reference to comparator input for output voltage sensing. Use Value: ±2 % tolerance ensures output accuracy within ±0.72 V at 36 V setpoint, reducing need for post-production trimming. |
Use Scenario: Protecting microcontroller I/O pins from ESD or inductive kickback exceeding 36 V. IC Role / Device Role / Timing Role: Shunts excess energy to ground when reverse voltage exceeds 36 V threshold. Use Value: 250 Ω differential resistance limits clamping voltage rise under 10 mA fault current to ≤38.5 V. |
| Signal Level Translation | Current Source Biasing |
|
Use Scenario: Setting bias point for op-amp input stages requiring stable 36 V rail. IC Role / Device Role / Timing Role: Acts as passive voltage source in high-impedance node with minimal quiescent current draw. Use Value: ≤60 μA reverse leakage at 28.8 V ensures negligible loading on sensitive analog nodes. |
Use Scenario: Establishing constant current through LED strings or sensor bridges. IC Role / Device Role / Timing Role: Maintains fixed voltage drop across series resistor to generate stable current. Use Value: +0.05 mV/K temperature coefficient yields <0.18 mV/°C drift over 0–85 °C, minimizing current variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C36,115 | ±5 % tolerance, higher differential resistance (≤300 Ω), same SOD123F package | Acceptable where 36 V ±1.8 V tolerance suffices and cost is prioritized | Select for cost-sensitive consumer electronics where tighter regulation is unnecessary |
| MMSZ5245B-7-F | ±5 % tolerance, 36 V nominal, SOD-123 package (identical footprint), 500 mW Ptot | Limited power handling requires derating above 70 °C ambient | Choose only for low-power, thermally benign environments with no surge exposure |
Compared with BZT52H-B36,115, the BZT52C36,115 trades regulation precision for lower unit cost, while MMSZ5245B-7-F sacrifices 330 mW of power margin and lacks specified non-repetitive surge rating-making the Nexperia part preferable for industrial-grade reliability and thermal robustness.

FAQ
What is the Zener test current for BZT52H-B36,115?
The BZT52H-B36,115 is characterized at IZ = 2 mA, as confirmed in Table 9 of the datasheet. This current establishes the nominal 36 V breakdown voltage and associated parameters including differential resistance and temperature coefficient. Operation outside this condition alters VZ and rdif values per the device's IV curve.
Can BZT52H-B36,115 be used in automotive applications?
No. The BZT52H-B36,115 is explicitly designated as non-automotive qualified per Revision History section 13, which states "Products changed to non-automotive qualification" in Rev. 7. Automotive use requires Nexperia's -Q qualified variants such as BZT52H-B36-Q, which undergo additional AEC-Q101 stress testing and qualification.
How does the SOD123F package affect thermal performance?
The SOD123F package achieves Rth(j-sp) = 150 K/W (junction-to-solder point) when mounted on an FR4 PCB with single-sided 1 cm² cathode pad. This allows 830 mW dissipation at Tamb ≤ 25 °C but requires thermal derating above that ambient-e.g., ~500 mW at 70 °C-due to the package's limited copper interface area and plastic encapsulation.
What is the meaning of the "E7" marking on BZT52H-B36,115?
Per Table 4, "E7" is the standardized marking code for BZT52H-B36. It appears as a laser-etched or molded identifier on the cathode end of the SOD123F body and serves as a quick visual verification of part identity during assembly and inspection-distinct from the ±2 % tolerance grade (B-series) and 36 V nominal voltage.
