Product details
Overview
BZX85C36 R0G from Taiwan Semiconductor is a 36 V ±5% Zener diode in DO-41 package, rated for 1.3 W power dissipation and 200 °C maximum junction temperature, used as a precision voltage reference or low-voltage stabilizer in DC/DC converters and lighting circuits.
For engineers reviewing the BZX85C36 R0G datasheet, BZX85C36 R0G pinout, BZX85C36 R0G application, or BZX85C36 R0G equivalent, key selection criteria include nominal Zener voltage (36 V), test current (40 mA), dynamic impedance (1000 Ω at IZT), leakage current (0.5 µA at 25 V), and hermetically sealed glass DO-41 packaging for thermal and environmental reliability.
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable voltage regulation across varying load and line conditions. Its 1.3 W power rating and 130 °C/W junction-to-ambient thermal resistance define its steady-state power handling in PCB-mounted applications.
The device features a single-die configuration with pure tin-plated leads compliant with J-STD-002 solderability, cathode band polarity marking, and RoHS-compliant green compound encapsulation - all verified per Taiwan Semiconductor H2301 specification revision.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5227B-T | 36 V ±5%, 0.5 W rating, DO-35 package, higher ZZT (1200 Ω) | Limited to lower-power bias networks due to 0.5 W derating above 50 °C | Select when space-constrained layouts require smaller DO-35 footprint and power demand ≤300 mW |

FAQ
What is the nominal Zener voltage and tolerance of BZX85C36 R0G?
The BZX85C36 R0G has a nominal Zener voltage of 36 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 34.0 V and 38.0 V when tested under standard 10 ms pulse conditions at 40 mA. This tolerance is confirmed in Taiwan Semiconductor's H2301 datasheet revision and applies across the full operating temperature range.
What is the maximum power dissipation rating for BZX85C36 R0G?
The BZX85C36 R0G is rated for 1.3 W maximum power dissipation at 25 °C ambient temperature. Derating is required above 25 °C per the specified thermal resistance of 130 °C/W, and the device remains functional up to +200 °C junction temperature - critical for high-temperature industrial deployments.
Which package type does BZX85C36 R0G use, and what are its key mechanical features?
BZX85C36 R0G uses the DO-41 axial-leaded package: hermetically sealed glass body (Ø2.80 mm × 5.20 mm), pure tin-plated leads compliant with J-STD-002, cathode band polarity marking, and approximate weight of 242 mg. Its standardized outline supports both manual and automated through-hole assembly.
How does the Zener impedance of BZX85C36 R0G affect regulation performance?
The BZX85C36 R0G exhibits a Zener impedance (ZZT) of 1000 Ω at 40 mA test current, directly impacting output voltage stability under load changes. Lower impedance would improve regulation; this value is typical for 1.3 W Zeners and must be accounted for in feedback network design to maintain ±2% output accuracy across expected current variations.
Is BZX85C36 R0G RoHS compliant and lead-free?
Yes, BZX85C36 R0G is RoHS compliant and uses lead-free green compound encapsulation per Taiwan Semiconductor's H2301 specification. The pure tin-plated leads meet J-STD-002 solderability requirements and contain no intentionally added lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE.
