Product details
Overview
1N5233B/TR from Microsemi is a 6.0 V, ±5% tolerance, 500 mW glass axial-lead Zener diode in DO-35 (DO-204AH) package, rated for 20 mA test current and 7.0 Ω dynamic impedance at IZK = 0.25 mA, used for precision voltage regulation in low-power analog reference and power supply feedback circuits.
For engineers reviewing the 1N5233B/TR datasheet, 1N5233B/TR pinout, 1N5233B/TR application, or 1N5233B/TR equivalent, this page delivers verified electrical specs, thermal derating behavior, temperature coefficient (+0.038 %/°C), RoHS-compliant packaging with "TR" tape-and-reel option, and direct alternatives for voltage reference design.
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable DC voltage across its terminals under varying load and temperature conditions. It exhibits a sharp knee at 20 mA test current and low dynamic impedance (7.0 Ω), enabling accurate regulation in shunt-mode configurations.
Its DO-35 glass package provides hermetic sealing, -65°C to +175°C operating range, and inherent radiation hardness per MicroNote 050. The cathode band marking defines polarity, and it requires banded-end-positive biasing for Zener conduction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A | 6.2 V nominal, ±5%, 1.0 W power rating, DO-41 package | Higher power dissipation and larger footprint; suitable for higher-current shunt loads | Select when >500 mW headroom or board space permits larger axial package |
| MMBZ5233B | 6.0 V nominal, ±5%, SOT-23 surface-mount package, 225 mW rating | Smaller size and automated assembly compatibility but lower power and different thermal path | Select for space-constrained PCBs where 225 mW suffices and reflow compatibility is required |
Compared with 1N5233B/TR, 1N4735A offers higher power margin in a larger DO-41 case, while MMBZ5233B trades power and thermal robustness for miniaturization and SMT process alignment-neither is pin-compatible due to differing packages and lead forms.

FAQ
What is the nominal Zener voltage and tolerance of the 1N5233B/TR?
The 1N5233B/TR has a nominal Zener voltage of 6.0 V with a tolerance of ±5%, as designated by the "B" suffix per JEDEC standards. This value is measured at 20 mA test current and remains stable across its specified operating temperature range of -65°C to +175°C. The 1N5233B/TR achieves this accuracy through controlled doping and glass-package hermetic sealing.
What package type and marking does the 1N5233B/TR use?
The 1N5233B/TR uses the DO-35 (DO-204AH) glass axial-lead package with a black cathode band marking. Its leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026. The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement. The 1N5233B/TR body is marked with its full part number.
How does the temperature coefficient affect the 1N5233B/TR's performance?
The 1N5233B/TR has a positive temperature coefficient of +0.038 %/°C, meaning its Zener voltage increases predictably with rising junction temperature. This characteristic allows designers to compensate for thermal drift in reference circuits-especially valuable in industrial environments where ambient temperatures fluctuate. The 1N5233B/TR maintains this coefficient across its full operating range, validated per Microsemi MicroNote 202.
Can the 1N5233B/TR be used in surface-mount designs?
No-the 1N5233B/TR is an axial-leaded DO-35 device and is not compatible with surface-mount assembly processes. For SMT equivalents, consider the MMBZ5233B in SOT-23 package, which shares the same 6.0 V ±5% specification but has lower power rating (225 mW) and different thermal characteristics. The 1N5233B/TR requires through-hole mounting with 3/8" lead length for rated power dissipation.
What is the maximum reverse leakage current for the 1N5233B/TR?
The 1N5233B/TR specifies a maximum reverse leakage current (IR) of 50 μA at VR = 4.8 V, measured at 25°C. This low leakage supports energy-efficient operation in battery-powered applications and ensures minimal loading on high-impedance reference nodes. The 1N5233B/TR maintains this performance across its full storage and operating temperature range (-65°C to +175°C).
