Product details
Overview
BZT52H-B3V6,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD123F package, rated for 3.6 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 150 °C maximum junction temperature - used for precision low-voltage reference and overvoltage clamping in power supply feedback paths and I/O protection circuits.
For engineers reviewing the BZT52H-B3V6,115 datasheet, BZT52H-B3V6,115 pinout, BZT52H-B3V6,115 application, or BZT52H-B3V6,115 equivalent, this page delivers verified Zener voltage, differential resistance, thermal resistance, reverse current limits, and SOD123F mounting details required for stable 3.6 V regulation in space-constrained PCB designs.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a tightly controlled 3.6 V nominal Zener voltage (VZ) at IZ = 5 mA, exhibiting ≤95 Ω differential resistance (rdif) and <5 μA reverse current (IR) at VR = 1 V. Its temperature coefficient is −3.5 mV/K, indicating predictable negative drift over temperature.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it achieves 70 K/W junction-to-solder-point thermal resistance when mounted with a 1 cm² cathode pad, enabling reliable operation up to 830 mW at Tamb ≤ 25 °C without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 3.53 V to 3.67 V at IZ = 5 mA - ensures ±2 % regulation accuracy for 3.6 V reference applications |
| Differential Resistance rdif | ≤95 Ω - minimizes output voltage variation under load current changes in feedback loops |
| Reverse Current IR | <5 μA at VR = 1 V - guarantees low leakage in standby or high-impedance sensing nodes |
| Total Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C - supports continuous regulation in compact layouts with adequate copper area |
| Junction-to-Solder-Point Rth(j-sp) | 70 K/W - enables thermal design using cathode pad as primary heat path in reflow-soldered SOD123F footprint |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - defines conduction threshold during forward-biased ESD clamp events |
| Non-repetitive Peak Reverse Current IZSM | 6.0 A (tp = 100 μs) - specifies surge handling capability for transient overvoltage suppression |
Pinout & Package
SOD123F is a small-outline, flat-lead, surface-mounted plastic package with two terminals and a cathode-marking bar. Dimensions: 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), with 0.7 mm lead pitch and 0.55 mm lead width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-bias anode connection point for Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms the reference return path for Zener current flow |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tighter regulation than ±5 % variants, reducing need for post-regulation trimming in 3.6 V LDO feedback or ADC reference circuits |
| 830 mW power rating at Tamb ≤ 25 °C | Supports higher Zener current in compact designs without derating, improving noise immunity in analog references |
| 70 K/W junction-to-solder-point thermal resistance | Allows direct thermal coupling to PCB copper, simplifying thermal management versus larger packages like DO-214AC |
| Low 5 μA max reverse leakage at 1 V | Maintains signal integrity in high-impedance sensor bias networks and battery-monitoring dividers |
| SOD123F footprint compatibility | Matches industry-standard reflow soldering profiles and automated placement equipment, ensuring manufacturability in high-volume production |
Applications
| Power Supply Feedback Reference | I/O Pin ESD Protection |
|---|---|
Use Scenario: Stabilizing output voltage of a 3.3 V buck converter via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Zener diode provides precise 3.6 V reference to bias optocoupler LED, setting regulation threshold. Use Value: ±2 % VZ tolerance ensures output stays within ±1.5 % of 3.3 V across line/load/temperature, meeting industrial PSU specs. |
Use Scenario: Protecting a microcontroller GPIO pin against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Placed between I/O line and ground to clamp transients above 3.6 V while blocking normal 0–3.3 V signals. Use Value: 6.0 A non-repetitive peak current rating absorbs full ESD pulse energy without degradation, preserving pin reliability. |
| ADC Voltage Reference Divider | Low-Voltage Brown-Out Detection |
Use Scenario: Generating a stable 1.8 V reference from 3.6 V rail for SAR ADC internal reference buffer. IC Role / Device Role / Timing Role: Zener sets upper node of resistive divider; low rdif (<95 Ω) prevents loading-induced error. Use Value: ≤5 μA reverse leakage avoids measurable current injection into high-Z ADC reference input, maintaining 12-bit accuracy. |
Use Scenario: Detecting system brown-out when main 3.3 V rail drops below 2.9 V using comparator hysteresis. IC Role / Device Role / Timing Role: Zener + resistor network creates 3.6 V threshold; comparator compares rail to this reference. Use Value: −3.5 mV/K temperature coefficient allows predictable threshold shift, enabling accurate trip-point calibration across −40 °C to +85 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C3V6,115 | ±5 % tolerance (3.4–3.8 V), same SOD123F package and 830 mW rating | Acceptable where 3.6 V reference accuracy is secondary to cost; higher VZ spread increases output variance in feedback loops | Select when budget constraints outweigh regulation precision needs in non-critical power rails |
| MMSZ5226B-7-F | ±5 % tolerance, SOD-123 package (mechanically identical), 500 mW rating, 3.6 V nominal | Lower power rating requires current limiting below 139 mA; less suitable for high-current shunt regulation | Choose only if legacy MMSZ footprint compatibility is mandatory and thermal headroom permits 500 mW operation |
Compared with BZT52C3V6,115 and MMSZ5226B-7-F, the BZT52H-B3V6,115 delivers superior voltage accuracy and 66 % higher power handling - critical for stable feedback regulation and robust transient clamping without external current limiting.

FAQ
What is the guaranteed Zener voltage range for BZT52H-B3V6,115 at 5 mA test current?
The BZT52H-B3V6,115 has a guaranteed Zener voltage range of 3.53 V to 3.67 V when tested at IZ = 5 mA and Tj = 25 °C, reflecting its ±2 % tolerance specification. This range is confirmed in Table 8 of the official Nexperia datasheet Rev. 7 and applies to all units within the B-series tolerance grade.
Can BZT52H-B3V6,115 be used in place of a 3.3 V Zener diode for overvoltage protection?
No - BZT52H-B3V6,115 is specified for 3.6 V nominal breakdown and will not reliably clamp at 3.3 V. At 3.3 V reverse bias, its leakage remains below 1 μA (per Fig. 8), providing no meaningful clamping action. For 3.3 V protection, select BZT52H-B3V3,115 (3.23–3.37 V range) instead.
What is the maximum continuous Zener current for reliable operation at 70 °C ambient temperature?
At Tamb = 70 °C, the device must be derated linearly from 830 mW at 25 °C using the 70 K/W junction-to-solder-point thermal resistance. Maximum allowable power is 830 mW − (70−25) K × (1/70) K/W × 1000 mW/W = 515 mW. With VZ ≈ 3.6 V, max continuous IZ ≈ 143 mA.
Does the SOD123F package support hand-soldering with a standard iron?
The SOD123F package is designed for reflow soldering per JEDEC standards and is not recommended for hand-soldering. Its small size (1.7 mm width), flat leads, and thermal mass make consistent joint formation difficult with irons; risk of tombstoning, cold joints, or pad lifting is high. Reflow profiling is required for reliable assembly.
