Product details
Overview
BZX85C5V6_T50A from ON Semiconductor is a 5.6 V, ±5% tolerance, 1.0 W axial-leaded Zener diode in DO-41 glass package, rated for -65°C to +200°C operation, with 45 Ω zener impedance at 45 mA test current, used for voltage regulation and overvoltage protection in power supply feedback loops and reference circuits.
For engineers reviewing the BZX85C5V6_T50A datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance, power dissipation derating above 50°C, thermal resistance, leakage current at rated reverse voltage, and DO-41 mechanical compatibility with through-hole PCB layouts.
Technical Context
The BZX85C5V6_T50A operates as a silicon planar Zener diode with controlled avalanche breakdown at nominal 5.6 V, specified under thermal equilibrium conditions at lead temperature TL = 30°C ±1°C and 3/8″ lead length. Its 5% tolerance and 45 Ω dynamic impedance (ZZ) at IZ = 45 mA support stable DC voltage reference generation.
It exhibits 2 μA maximum leakage current (IR) at VR = 1 V and 1.2 V forward voltage (VF) max at IF = 200 mA, enabling bidirectional clamping capability. Absolute maximum power dissipation is 1.0 W at TA = 25°C, derating linearly at 6.67 mW/°C above 50°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2 V min / 6.0 V max - defines regulated output range under 45 mA test current; critical for precision reference design margin. |
| Power Dissipation (PD) | 1.0 W @ TA = 25°C - sets maximum continuous power handling before thermal shutdown or degradation. |
| Zener Impedance (ZZ) | 45 Ω @ IZ = 45 mA - determines regulation stiffness; lower values improve load/line transient response. |
| Leakage Current (IR) | 2 μA max @ VR = 1 V - ensures minimal quiescent current draw in high-impedance bias networks. |
| Operating Temp Range | -65°C to +200°C - supports industrial, automotive under-hood, and aerospace environments without derating. |
| Forward Voltage (VF) | 1.2 V max @ IF = 200 mA - enables use as bidirectional clamp or low-drop rectifier in protection circuits. |
Pinout & Package
DO-41 glass axial package with cathode indicated by color band; leads are unmarked anode/cathode terminals suitable for through-hole mounting. Mechanical dimensions comply with JEDEC DO-204AL standard: body diameter 2.03–2.72 mm, overall length ≥25.40 mm, lead diameter 0.71–0.86 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias | Connected to lower-potential node; enables forward conduction at ≤1.2 V for clamping or sensing. |
| Cathode | Current exit terminal in forward bias; Zener breakdown terminal in reverse bias | Marked with color band; connected to higher-potential node in regulation mode to maintain 5.6 V reference. |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Ensures predictable regulation window across production lots without post-assembly trimming. |
| 1.0 W power rating with 6.67 mW/°C derating | Supports robust thermal management in compact enclosures using standard PCB copper pour heat sinking. |
| Low 45 Ω dynamic impedance at 45 mA | Maintains <1% output variation over 10–100 mA load current changes in shunt regulator topologies. |
| 2 μA max leakage at 1 V reverse bias | Minimizes error in high-gain op-amp reference buffers and battery-powered sensor bias networks. |
| DO-41 glass package with -65°C to +200°C rating | Enables direct replacement of legacy 1N4732A/1N5232B in harsh-environment designs without requalification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | Same 5.6 V nominal, but ±5% tolerance and 1.0 W rating; higher 60 Ω ZZ @ 45 mA; DO-41 plastic package. | Limited to commercial temp range (-65°C to +175°C); less suitable for high-reliability automotive under-hood use. | Select when cost sensitivity outweighs extended temperature needs and slightly higher impedance is acceptable. |
| BZX55C5V6 | Same 5.6 V, ±5%, 500 mW rating; 60 Ω ZZ @ 5 mA; DO-35 glass package; lower power handling. | Not suitable for >0.5 W continuous dissipation; requires tighter layout spacing due to smaller DO-35 footprint. | Choose only for space-constrained low-power applications where 1.0 W headroom is unnecessary. |
Compared with 1N4734A and BZX55C5V6, the BZX85C5V6_T50A delivers superior thermal robustness (200°C max), lower dynamic impedance, and full 1.0 W capability-making it optimal for industrial power supplies and high-reliability clamping where sustained power and wide temperature operation are mandatory.

FAQ
What is the exact Zener voltage range for BZX85C5V6_T50A?
The BZX85C5V6_T50A has a guaranteed Zener voltage range of 5.2 V minimum to 6.0 V maximum at IZ = 45 mA and TL = 30°C ±1°C, per ON Semiconductor's BZX85C3V3–BZX85C56 datasheet Rev. 2. This 5% tolerance band ensures consistent regulation performance across production units without binning.
Does BZX85C5V6_T50A support bidirectional voltage clamping?
Yes, the BZX85C5V6_T50A supports bidirectional clamping: it regulates at 5.2–6.0 V in reverse bias and conducts at ≤1.2 V forward voltage at 200 mA, enabling dual-role protection in I/O interface circuits. Its 2 μA leakage at 1 V reverse bias preserves signal integrity in high-impedance nodes.
What is the thermal derating behavior of BZX85C5V6_T50A above 50°C?
The BZX85C5V6_T50A derates linearly at 6.67 mW/°C above 50°C ambient temperature, reducing maximum allowable power dissipation from 1.0 W at 25°C to approximately 0.67 W at 100°C. This derating curve is defined in the Absolute Maximum Ratings table and must be applied in thermal design calculations.
Is BZX85C5V6_T50A compatible with DO-41 footprint layouts?
Yes, the BZX85C5V6_T50A uses the JEDEC DO-41 (DO-204AL) axial glass package with standardized lead spacing and body dimensions. Its mechanical drawing matches DO41AREV2, ensuring drop-in compatibility with existing DO-41 footprints on PCBs designed for 1N47xx or other DO-41 Zeners.
What is the maximum leakage current specification for BZX85C5V6_T50A?
The BZX85C5V6_T50A specifies a maximum leakage current (IR) of 2 μA at VR = 1 V and TA = 25°C. This low leakage supports accurate biasing in high-impedance reference circuits and minimizes standby power loss in battery-operated systems where the device remains reverse-biased continuously.
