Product details
Overview
BZX79C5V6-T50A from ON Semiconductor is a 5.6 V, 5% tolerance, 500 mW DO-35 glass-encapsulated Zener diode optimized for voltage regulation and reference applications in low-power analog circuits, power supply feedback loops, and overvoltage protection. It delivers 5 mA test current, 40 Ω dynamic impedance at IZ, and −2.0 mV/°C temperature coefficient.
For engineers reviewing the BZX79C5V6-T50A datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage accuracy, thermal stability in ambient ranges from −65°C to +200°C, leakage current ≤1 μA at 2 V reverse bias, and compatibility with lead-forming and wave-soldering processes per DO-35 mechanical outline.
Technical Context
The BZX79C5V6-T50A operates as a two-terminal voltage reference device where reverse-biased breakdown provides stable DC voltage clamping. Its −2.0 mV/°C temperature coefficient indicates slight negative drift with rising junction temperature, requiring thermal derating above 75°C at 4.0 mW/°C.
Designed for general-purpose regulation, it exhibits 1.5 V maximum forward voltage at 100 mA and 95 pF capacitance at zero bias (1 MHz), making it suitable for low-frequency stabilization rather than RF bypassing. The DO-35 package supports axial lead mounting with cathode band identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2 V to 6.0 V at IZ = 5 mA - defines regulated output range under nominal test conditions |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous thermal load on leads |
| Dynamic Impedance (ZZ) | 40 Ω max at IZ = 5 mA - determines regulation stiffness against load current variation |
| Temperature Coefficient (TC) | −2.0 mV/°C - quantifies voltage drift per degree Celsius rise in junction temperature |
| Leakage Current (IR) | ≤1 μA at VR = 2 V - ensures minimal parasitic current in standby or high-impedance bias networks |
| Junction Temperature Range | −65°C to +200°C - enables operation in automotive under-hood, industrial control, and aerospace environments |
Pinout & Package
DO-35 glass axial-leaded package with cathode identified by a single color band. Leads are tinned copper-clad steel, rated for 3/8″ lead length thermal dissipation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | Same 5.6 V nominal rating but 5% tolerance, 1 W power rating, DO-41 package | Higher power handling supports higher-current regulation; larger DO-41 footprint requires PCB redesign | Select when >500 mW dissipation is required and board space allows DO-41 layout |
| MMSZ5232B | 5.6 V, 5% tolerance, SOD-123 surface-mount package, 500 mW rating | No axial leads; suited for automated pick-and-place and compact PCBs | Select for space-constrained or high-volume SMT production where DO-35 is incompatible |
Compared with 1N4734A and MMSZ5232B, the BZX79C5V6-T50A offers identical voltage specification and power rating in a legacy-compatible DO-35 through-hole package, making it optimal for repair, prototyping, and industrial systems where axial lead reliability and serviceability are prioritized.

FAQ
What is the Zener voltage tolerance of BZX79C5V6-T50A?
The BZX79C5V6-T50A has a specified Zener voltage tolerance of ±5%, meaning its breakdown voltage falls between 5.2 V and 6.0 V when tested at 5 mA. This tolerance is guaranteed across the full operating temperature range and is consistent with the BZX79C family's standard grading. The BZX79C5V6-T50A achieves this without laser trimming, supporting high-volume cost-sensitive designs.
What is the maximum power dissipation for BZX79C5V6-T50A?
The BZX79C5V6-T50A is rated for 500 mW maximum power dissipation at lead temperature (TL) ≤ 75°C with 3/8″ lead length. Above 75°C, it must be derated linearly at 4.0 mW/°C. This thermal limit reflects the DO-35 glass package's ability to conduct heat through axial leads and is critical for sustained operation in enclosed or high-ambient environments.
Does BZX79C5V6-T50A have a specified forward voltage?
Yes, the BZX79C5V6-T50A has a maximum forward voltage of 1.5 V at 100 mA forward current. This parameter is defined in the datasheet and confirms its usability in bidirectional clamping or low-voltage rectification roles. Unlike many Zener diodes, the BZX79C5V6-T50A's forward characteristic is explicitly characterized, enabling dual-mode circuit design.
What is the temperature coefficient of BZX79C5V6-T50A?
The BZX79C5V6-T50A has a temperature coefficient of −2.0 mV/°C, indicating its Zener voltage decreases slightly as junction temperature increases. This value is measured and specified in the official ON Semiconductor datasheet for the BZX79C5V6-T50A and applies across the full operating range. It enables predictable drift modeling in temperature-critical reference applications.
Is BZX79C5V6-T50A compatible with lead-free soldering processes?
Yes, the BZX79C5V6-T50A features tinned copper-clad steel leads compatible with standard lead-free reflow and wave soldering profiles. Its DO-35 glass body withstands peak temperatures up to 260°C for 10 seconds, meeting IPC/JEDEC J-STD-020 requirements. The BZX79C5V6-T50A is qualified for RoHS-compliant manufacturing without derating or special handling.
