Product details
Overview
1N5236CRL from ON Semiconductor (formerly Motorola) is a 500 mW, ±2% tolerance, 7.5 V zener voltage regulator diode in DO-204AH (DO-35) glass package. It operates with 20 mA test current, exhibits 6 Ω dynamic impedance at IZT, and maintains stable regulation in low-power reference and voltage-clamp circuits for industrial power supplies and sensor signal conditioning.
For engineers reviewing the 1N5236CRL datasheet, pinout, applications, or equivalent options, this device serves as a precision voltage reference where tight tolerance (±2%), low zener impedance, and hermetically sealed glass construction are required for thermal stability and long-term reliability in ambient temperatures from –65°C to +200°C.
Technical Context
This axial-leaded silicon zener diode uses metallurgically bonded double-slug construction inside a hermetically sealed glass case (Case 299-02), enabling robust thermal performance and corrosion resistance. Its cathode band polarity marking and 230°C soldering tolerance support automated assembly and high-reliability mounting in any orientation.
The device delivers 7.5 V nominal regulation at 20 mA with ±2% initial tolerance, +0.058%/°C temperature coefficient, and 3 µA maximum reverse leakage at 6 V. Its 500 mW DC power rating derates linearly above 75°C lead temperature, supporting operation in compact, unheatsinked designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5236B | ±5% tolerance (vs. ±2% for 1N5236CRL); identical VZ, IZT, ZZT, package, and temperature coefficient | Suitable for cost-sensitive, non-critical references where tighter tolerance is unnecessary | Select 1N5236B when ±5% regulation accuracy suffices and BOM cost reduction is prioritized |
| BZX55-C7V5 | Same 7.5 V ±5%, DO-35 package, but higher ZZT (10 Ω typical) and wider temp coefficient range (±0.05 to +0.07%/°C) | Acceptable for general-purpose clamping where dynamic impedance and TC consistency are secondary | Choose BZX55-C7V5 only if sourcing flexibility is needed and ±5% tolerance aligns with system requirements |
Compared with 1N5236B and BZX55-C7V5, the 1N5236CRL delivers superior initial accuracy and tighter temperature coefficient control-critical for applications requiring stable reference voltage over temperature without calibration.

FAQ
What is the zener voltage tolerance of the 1N5236CRL?
The 1N5236CRL has a nominal zener voltage of 7.5 V with a tight ±2% tolerance, verified at 20 mA test current and 25°C ambient. This tighter tolerance compared to the ±5% 1N5236B variant reduces calibration effort in precision reference designs and improves system-level voltage accuracy across production batches.
What is the maximum power dissipation for the 1N5236CRL?
The 1N5236CRL is rated for 500 mW DC power dissipation at lead temperature (TL) ≤ 75°C, derating linearly at 4 mW/°C above that point. Its DO-204AH glass package and double-slug construction allow reliable operation up to +200°C junction temperature, making it suitable for unheatsinked, high-ambient applications.
How does the temperature coefficient affect the 1N5236CRL's regulation accuracy?
The 1N5236CRL has a specified temperature coefficient of +0.058 %/°C, meaning its zener voltage increases predictably with rising temperature. This positive, well-characterized drift enables straightforward compensation in temperature-critical references-unlike devices with wider or bipolar TC spreads that introduce uncertainty.
Can the 1N5236CRL be used in surface-mount designs?
No-the 1N5236CRL is an axial-leaded DO-204AH (DO-35) glass device intended for through-hole mounting. It lacks surface-mount terminations or tape-and-reel packaging compatible with SMT placement. For SMT equivalents, consider SOD-123 or SOD-323 packaged zeners with matching electrical specs.
What is the reverse leakage current specification for the 1N5236CRL?
The 1N5236CRL specifies a maximum reverse leakage current (IR) of 3 µA at 6 V reverse voltage and 25°C. This low leakage supports energy-efficient operation in battery-powered monitoring circuits and ensures minimal loading on high-impedance sensor nodes where current draw must be minimized.
