Product details
Overview
BZT52H-B8V2,115 from Nexperia is a ±2 % tolerance Zener diode in SOD123F package, rated for 8.2 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 150 °C maximum junction temperature - used for precision voltage reference and overvoltage protection in low-power DC rails.
For engineers reviewing the BZT52H-B8V2,115 datasheet, BZT52H-B8V2,115 pinout, BZT52H-B8V2,115 application, or BZT52H-B8V2,115 equivalent, this page delivers verified Zener parameters, thermal resistance values, differential resistance, temperature coefficient, and real-world mounting guidance for surface-mount voltage regulation design.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a tightly controlled 8.2 V nominal working voltage (±2 %) at IZ = 5 mA, exhibiting 80 Ω maximum differential resistance and +3.2 to +6.2 mV/K positive temperature coefficient across its operating current range. Its low 150 K/W junction-to-solder-point thermal resistance enables stable regulation under moderate PCB copper area constraints.
The device uses planar epitaxial construction in an SOD123F plastic package with cathode-marked anode-cathode polarity, optimized for reflow soldering on FR4 PCBs with single-sided 1 cm² cathode pad - supporting reliable operation up to 250 mA forward current and 40 W non-repetitive peak reverse power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 8.04 V to 8.36 V at IZ = 5 mA - ensures ±2 % regulation accuracy in feedback or clamp circuits |
| Differential Resistance (rdif) | ≤ 80 Ω - minimizes output voltage shift under load current variation |
| Reverse Current (IR) | ≤ 0.7 μA at VR = 6.56 V - guarantees low leakage in standby or high-impedance bias networks |
| Temperature Coefficient (SZ) | +3.2 to +6.2 mV/K - enables predictable drift compensation in temperature-sensitive references |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C on FR4 with 1 cm² cathode pad - defines safe continuous DC power handling |
| Junction-to-Ambient Rth | 330 K/W in free air - informs derating curves for natural-convection board-level thermal design |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - supports use as low-drop rectifier or ESD clamping diode in bidirectional protection |
Pinout & Package
SOD123F surface-mount plastic package: 2-terminal, flat lead, 3.4–3.6 mm length × 1.5–1.7 mm width × 0.25–0.35 mm height; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-bias voltage applied here relative to anode |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms the reference return path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VZ tolerance | Enables tighter voltage margin control than ±5 % variants in feedback loops and reference dividers |
| 830 mW power rating | Supports higher current regulation (up to ~100 mA at 8.2 V) without external heatsinking on standard FR4 |
| Low 80 Ω rdif | Reduces regulation error to < 8 mV per 1 mA load change - critical for analog sensor supply stability |
| +3.2 to +6.2 mV/K SZ | Allows predictable thermal drift modeling when paired with negative-coefficient components for compensated references |
| SOD123F footprint | Compatible with automated pick-and-place and reflow processes; occupies only 5.8 mm² PCB area |
Applications
| Power Supply Voltage Reference | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Providing stable 8.2 V reference for ADC voltage dividers and op-amp bias networks in industrial sensor modules. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference potential independent of input rail fluctuations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52H-C8V2 | ±5 % tolerance (7.7–8.7 V), higher 150 Ω rdif, same SOD123F package | Acceptable where cost sensitivity outweighs regulation precision; less suitable for feedback paths | Select when ±5 % VZ meets system margin and lower unit cost is prioritized over thermal stability |
| MMSZ5233B-7-F | ±5 % tolerance (7.9–8.5 V), 100 Ω rdif, SOD-123 package, 500 mW Ptot | Lower power rating limits continuous current to ~60 mA; requires tighter thermal layout | Choose only if legacy MMSZ footprint compatibility is required and power demand stays below 400 mW |
Compared with BZT52H-B8V2,115, the BZT52H-C8V2 trades regulation accuracy for cost, while MMSZ5233B-7-F sacrifices 330 mW power headroom and thermal robustness - making the BZT52H-B8V2,115 optimal for designs needing ±2 % stability, 830 mW capability, and predictable +4.5 mV/K drift behavior.

FAQ
What is the maximum continuous reverse current for BZT52H-B8V2,115 at 25 °C ambient?
The device supports up to 100 mA continuous reverse current at 25 °C ambient when mounted on an FR4 PCB with 1 cm² cathode pad, based on its 830 mW power rating and 8.2 V breakdown voltage - exceeding typical 5–20 mA reference applications and enabling use in moderate-current clamp roles.
How does the +4.5 mV/K temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
Across that range, the coefficient causes approximately +0.73 V total drift (4.5 mV/K × 165 K), shifting nominal 8.2 V to ~8.93 V at +125 °C - but actual variation remains bounded by the ±2 % initial tolerance and measured SZ curve, which flattens above 10 mA, enabling predictable compensation in precision references.
Can BZT52H-B8V2,115 be used in place of a 1N4736A in existing designs?
No - the 1N4736A is a through-hole DO-41 device rated for 4.2 W and 1000 mW average power, whereas BZT52H-B8V2,115 is an SMD SOD123F part with 830 mW rating and different thermal path; direct substitution requires PCB redesign, thermal validation, and verification of surge immunity against the 40 W non-repetitive pulse spec.
What is the reverse leakage current at 6.56 V and 25 °C, and why does it matter for low-power systems?
Maximum reverse leakage is 0.7 μA at 6.56 V and 25 °C, confirmed in Table 8. This ultra-low value prevents parasitic discharge in battery-backed circuits and avoids loading high-impedance nodes - critical for maintaining >10-year shelf life in IoT endpoint sensors and minimizing quiescent current in always-on monitoring systems.
