Product details
Overview
BZT52H-C6V8,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 6.8 V nominal breakdown voltage at IZ = 5 mA, with 80 Ω typical differential resistance, 8 μA maximum reverse current at VR = 4.0 V, and 830 mW total power dissipation at Tamb ≤ 25 °C - used for precision voltage reference and overvoltage clamping in low-power analog signal conditioning circuits.
For engineers reviewing the BZT52H-C6V8,115 datasheet, BZT52H-C6V8,115 pinout, BZT52H-C6V8,115 application, or BZT52H-C6V8,115 equivalent, this page delivers verified Zener parameters, thermal performance data, cathode/anode terminal mapping, and direct-fit alternatives for stable voltage regulation in space-constrained PCB designs.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 6.8 V reference across load variations, with temperature coefficient of +1.2 mV/K at IZ = 5 mA - enabling predictable drift compensation in bias networks. Its low 80 Ω dynamic impedance ensures minimal output voltage variation under changing current conditions.
Designed for surface-mount assembly on FR4 PCBs with single-sided copper and tin-plated finish, it achieves 70 K/W junction-to-solder-point thermal resistance when mounted with 1 cm² cathode pad - supporting reliable operation up to 150 °C junction temperature under pulsed or continuous DC stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 6.4 V to 7.2 V at IZ = 5 mA - defines usable regulation window for 6.8 V nominal reference |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - determines output voltage stability against load current changes |
| Reverse Current (IR) | 8 μA max at VR = 4.0 V - specifies leakage level before breakdown onset |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction threshold in forward bias for protection or sensing roles |
| Thermal Resistance (Rth(j-sp)) | 70 K/W - quantifies junction-to-solder-point heat transfer efficiency for thermal design margining |
| Non-repetitive Peak Reverse Current (IZSM) | 6.0 A at tp = 100 μs - supports transient surge suppression in ESD-critical interfaces |
Pinout & Package
SOD123F is a small-outline, flat-lead surface-mount plastic package measuring 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), with gull-wing leads optimized for reflow soldering on standard FR4 PCBs using the footprint defined in Figure 12 of the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail - completes bias path for controlled breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % voltage tolerance | Enables cost-optimized selection where tight regulation is not required, e.g., non-critical biasing or coarse clamping |
| 830 mW power rating | Supports sustained regulation in 5–10 mA range without heatsinking on standard PCB layouts |
| Low 80 Ω dynamic impedance | Maintains < ±10 mV output shift per 1 mA load change - critical for stable reference in op-amp feedback paths |
| 150 °C maximum junction temperature | Allows deployment in industrial ambient environments up to +85 °C with adequate board thermal relief |
| SOD123F package compatibility | Enables automated placement and reflow processing with industry-standard 0805-class footprints and stencil apertures |
Applications
| Power Supply Rail Clamping | Op-Amp Reference Biasing |
|---|---|
|
Use Scenario: Clamp 12 V supply rail against transient spikes in microcontroller-based sensor nodes. IC Role / Device Role / Timing Role: Zener diode provides passive overvoltage protection by shunting excess current above 6.8 V to ground. Use Value: Limits rail excursion to safe levels below IC absolute maximum ratings, preventing latch-up or damage during ESD events. |
Use Scenario: Generate stable 6.8 V reference for instrumentation amplifier input stage calibration. IC Role / Device Role / Timing Role: Functions as precision voltage source in high-impedance divider network feeding op-amp non-inverting input. Use Value: Delivers < ±0.1 % regulation error over 1–10 mA load range due to low rdif, improving measurement accuracy. |
| ADC Input Protection | Logic-Level Translation |
|
Use Scenario: Protect 3.3 V ADC input from accidental 5 V misconnection in modular test equipment. IC Role / Device Role / Timing Role: Placed between signal line and ground to clamp input voltage to 6.8 V, limiting forward drop to 0.9 V. Use Value: Prevents ADC input stage damage while maintaining signal integrity below clamp threshold via low leakage (< 8 μA). |
Use Scenario: Shift 5 V logic signals down to 3.3 V compatible levels in mixed-voltage FPGA I/O banks. IC Role / Device Role / Timing Role: Used in series with current-limiting resistor to create fixed 6.8 V reference point for level-shifting network. Use Value: Enables deterministic voltage translation with < 10 ns propagation delay - no active circuitry or timing skew introduced. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5235BS-7-F (Diodes Inc.) | Same 6.8 V nominal, ±5 % tolerance, but SOT-323 package - 15 % smaller footprint, 100 mW lower Ptot | Preferred for ultra-dense layouts where thermal margin > 600 mW is acceptable | Select when board area is constrained and peak power remains < 730 mW |
| BZX84-C6V8 (Nexperia) | Same 6.8 V, ±5 %, but SOT-23 package - higher 350 mW Ptot, 120 Ω rdif, and 100 μA IR at VR = 4 V | Used where higher surge robustness is needed but tighter regulation is not critical | Choose when legacy SOT-23 tooling exists and 80 Ω rdif is unnecessary |
Compared with MMBZ5235BS-7-F, BZT52H-C6V8,115 offers 100 mW higher power headroom and 40 Ω lower impedance for improved regulation stability; versus BZX84-C6V8, it delivers tighter leakage control and superior thermal performance in compact SOD123F form factor.

FAQ
What is the maximum continuous reverse current this Zener can handle at 6.8 V?
The BZT52H-C6V8,115 is not rated for continuous reverse current at its nominal Zener voltage - it is designed to operate at IZ = 5 mA for specification compliance. Its absolute maximum reverse current is limited by power dissipation: at 6.8 V, continuous IZ must stay below 122 mA to remain within 830 mW Ptot, assuming Tamb ≤ 25 °C and proper PCB thermal relief.
Can this diode be used in place of a 6.2 V Zener for basic voltage reference?
No - the BZT52H-C6V8,115 has a guaranteed breakdown range of 6.4 V to 7.2 V at 5 mA, making it unsuitable as a direct replacement for a 6.2 V Zener. Substituting would introduce ≥200 mV systematic offset in reference-dependent circuits, violating accuracy requirements in applications like ADC calibration or precision comparators.
Does the SOD123F package support hand soldering with hot air?
Yes - the SOD123F package is compatible with hot-air rework tools operating at peak temperatures ≤ 350 °C for ≤ 10 seconds, provided preheating to 120 °C minimizes thermal shock. The device's 150 °C maximum junction temperature and lead-free termination allow compliant rework without delamination or parametric shift when following IPC-7711/7721 guidelines.
How does temperature affect regulation accuracy at 6.8 V?
At IZ = 5 mA, the BZT52H-C6V8,115 exhibits a +1.2 mV/K temperature coefficient, meaning its breakdown voltage increases by 1.2 mV per degree Celsius rise. Over a 0 °C to 70 °C ambient range, this results in a +84 mV total shift - a ±0.62 % deviation from nominal 6.8 V, which must be factored into reference-critical designs.
