Product details
Overview
1N5932BRL from onsemi is a 3 W, 20 V ±5% Zener diode in DO-41 axial package, designed for precision voltage regulation and overvoltage protection in DC power supplies, reference circuits, and surge-clamping applications. It delivers stable reverse breakdown at 20 V nominal with 18.7 Ω dynamic impedance at 14 mA test current and supports up to 75 mA maximum DC zener current.
For engineers reviewing the 1N5932BRL datasheet, pinout, applications, or equivalent options, this device serves as a leaded, Pb-free, industrial-grade Zener regulator with Class 3 ESD immunity (>16 kV HBM), 98 W surge capability (1 ms), and thermal stability across −65°C to +200°C operating range.
Technical Context
The 1N5932BRL operates as a silicon-oxide passivated junction Zener diode optimized for steady-state voltage clamping and low-noise reference generation. Its design centers on tight tolerance (±5%), low dynamic impedance (18.7 Ω @ IZT = 14 mA), and robust surge handling (98 W, 1 ms) - all enabled by thermoset plastic encapsulation and axial-lead mechanical construction.
It features cathode polarity marking, solderable leads rated to 260°C for 10 seconds at 1/16″ from case, and derated power dissipation: 3 W at TL = 75°C (lead length 3/8″), dropping linearly to 1 W at TA = 50°C. Reverse leakage is limited to ≤0.25 μA @ VR = 15.2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19.0–21.0 V (nominal 20 V, ±5% tolerance at IZT = 14 mA; enables precise DC rail clamping) |
| Zener Impedance (ZZT) | 18.7 Ω max @ IZT = 14 mA (low dynamic resistance ensures minimal output voltage variation under load changes) |
| Max DC Zener Current (IZM) | 75 mA (supports sustained regulation up to 1.5 W at 20 V without exceeding thermal limits) |
| Surge Power Rating | 98 W @ 1 ms (enables transient overvoltage suppression in input-stage protection circuits) |
| ESD Rating | Class 3 (>16 kV HBM) (provides robust handling during PCB assembly and field operation) |
| Operating Temperature | −65°C to +200°C (suitable for automotive under-hood, industrial control, and high-reliability embedded systems) |
| Package | DO-41 (axial-lead, void-free thermoset plastic; same footprint as legacy 1 W Zeners but rated for 3 W) |
Pinout & Package
Package: DO-41 axial-lead plastic case (Case 59, Style 1), cathode indicated by band. Leads are corrosion-resistant and readily solderable; max solder temperature 260°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased Zener terminal | Connected to higher-potential node in regulation/clamp configuration; carries full zener current during conduction |
| Anode | Forward-biased terminal / reference return | Typically tied to circuit ground or lower-potential rail; completes bias path for reverse operation |
Key Features
| Feature | Design Value |
|---|---|
| Precision voltage regulation | ±5% tolerance (B-suffix) ensures predictable clamping at 20 V across production lots and temperature |
| High surge resilience | 98 W non-repetitive pulse rating (1 ms) protects downstream circuitry from inductive kick or EFT events |
| Low leakage performance | ≤0.25 μA @ VR = 15.2 V minimizes standby current loss in battery-powered or low-power reference designs |
| Pb-free and RoHS-compliant | G-suffix variant available; meets global environmental compliance without sacrificing thermal or electrical performance |
| Compact 3 W rating in DO-41 | Same physical size as standard 1 W Zeners - simplifies board layout upgrades without footprint change |
Applications
| Power Supply Voltage Clamp | DC Reference Generator |
|---|---|
|
Use Scenario: Clamping unregulated 24 V DC input rails against overvoltage transients in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to shunt excess current and hold rail voltage at ≤21 V.

Use Value: Class 3 ESD rating (>16 kV) combined with fast turn-on ensures protection without false triggering or signal distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5932B | Same electrical specs and DO-41 package; differs only in packaging - bulk (2000/box) vs. tape-and-reel (6000/reel) | No functional difference; suited for manual prototyping or low-volume hand-soldering vs. automated SMT line feeding | Select 1N5932BRL for pick-and-place compatibility; choose 1N5932B for lab evaluation or small-batch builds |
| MMBZ5242B | SOT-23 surface-mount package; 12 V nominal, not 20 V; 225 mW rating, significantly lower power handling | Not interchangeable due to voltage mismatch and 13× lower power rating; unsuitable for 3 W clamping roles | Only consider MMBZ5242B for space-constrained, low-power 12 V reference use - not a functional alternative to 1N5932BRL |
Compared with 1N5932B (bulk version), 1N5932BRL offers identical electrical behavior with tape-and-reel logistics for automated assembly; MMBZ5242B is a different voltage grade and power class - not a drop-in replacement but a distinct product for miniature low-power designs.

FAQ
What is the Zener voltage tolerance of the 1N5932BRL?
The 1N5932BRL has a Zener voltage tolerance of ±5%, specified as 19.0 V minimum to 21.0 V maximum at IZT = 14 mA and TL = 30°C. This "B" suffix tolerance is guaranteed across the full operating temperature range and reflects onsemi's process control for stable regulation in production systems.
Can the 1N5932BRL be used in surface-mount designs?
No - the 1N5932BRL uses a DO-41 axial-lead package and is intended for through-hole mounting only. It is not compatible with SMT reflow processes. For surface-mount equivalents at 20 V, engineers must select different part families (e.g., SMA/Z series), as no SMT variant of the 1N5932BRL exists.
What is the maximum steady-state power dissipation for the 1N5932BRL?
The 1N5932BRL is rated for 3 W steady-state power dissipation at a lead temperature (TL) of 75°C with 3/8″ lead length. Above 75°C, it derates linearly at 24 mW/°C. At ambient temperature (TA) = 50°C, the rating drops to 1 W with derating of 6.67 mW/°C.
Does the 1N5932BRL meet RoHS and Pb-free requirements?
Yes - the "G" suffix in the ordering code (1N5932BRL, G) explicitly denotes a Pb-free, RoHS-compliant version. The device uses lead-free terminations and conforms to JEDEC standards for environmentally responsible manufacturing without compromising thermal or electrical performance.
How does the 1N5932BRL compare to older 1N4742A Zeners?
The 1N5932BRL replaces legacy 1N4742A with improved specs: tighter ±5% tolerance (vs. ±10%), higher 3 W rating (vs. 1 W), superior 98 W surge capability (vs. ~40 W), and Class 3 ESD rating (>16 kV). It shares the DO-41 footprint but delivers enhanced reliability for modern industrial and automotive applications.
