Product details
Overview
1N5932BRNG from onsemi is a 20 V ±5% Zener voltage regulator diode in DO-41 axial package, rated for 3 W steady-state power dissipation at 75°C lead temperature, 98 W surge capability at 1 ms, and ESD-rated Class 3 (>16 kV HBM). It operates from −65°C to +200°C and serves as a precision voltage reference or overvoltage clamp in DC power supply feedback loops.
For engineers reviewing the 1N5932BRNG datasheet, pinout, applications, or equivalent options, key selection criteria include its 20 V nominal Zener voltage, 18.7 Ω maximum impedance at 14 mA test current, 0.25 μA leakage at 15.2 V, 75 mA maximum DC Zener current, and Pb-free DO-41 Surmetic 30 packaging with cathode band polarity marking.
Technical Context
This device is a silicon-oxide passivated junction Zener diode optimized for stable voltage regulation under transient and steady-state conditions. Its thermal design relies on lead-to-ambient conduction (θJL = 25°C/W typical at L = 3/8″), and it exhibits low dynamic impedance (ZZT = 18.7 Ω) at IZT = 14 mA, enabling tight regulation in feedback networks.
The 1N5932BRNG features a defined temperature coefficient curve (positive above ~5 V), with VZ drift minimized by controlled junction design. Its surge rating (98 W @ 1 ms) and Class 3 ESD immunity support robust operation in industrial power rails where line transients and handling stress are common.

Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Used in optocoupler-coupled feedback loop of isolated 24 V DC-DC converter to regulate output voltage within ±1%. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 20 V reference to TL431-like control IC input. Use Value: Enables stable regulation despite input ripple and load step changes due to low ZZT and high surge tolerance. | Use Scenario: Clamps amplifier output during overvoltage fault in 4–20 mA transmitter front-end. IC Role / Device Role / Timing Role: Overvoltage protection element limiting signal rail to 20 V to prevent op-amp saturation or ADC damage. Use Value: Survives repetitive 60 V transients per IEC 61000-4-4 due to 98 W/1 ms surge rating and Class 3 ESD hardening. |
| Automotive Body Control Module | Programmable Logic Controller Input Protection |
Use Scenario: Stabilizes 5 V microcontroller reference rail fed from unregulated 12 V battery via series resistor in BCM subassembly. IC Role / Device Role / Timing Role: Precision Zener shunt regulator maintaining stable logic supply under cold-crank (6 V) and load-dump (36 V) conditions. Use Value: Maintains regulation across −40°C to +125°C ambient due to wide TJ range and predictable VZ tempco. | Use Scenario: Protects 24 V digital input channel from field-wiring induced surges in factory automation PLC rack. IC Role / Device Role / Timing Role: Primary clamping diode diverting surge energy before TVS or series resistor. Use Value: Reduces required TVS size by absorbing initial 1 ms surge energy, lowering system BOM cost and PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5932B | Same electrical specs but SnPb-plated leads; not Pb-free | Not compliant with RoHS or J-STD-020 reflow profiles requiring Pb-free solder | Select only for legacy repair or non-RoHS environments where leaded finish is mandated |
| MMSZ5248BT1G | SOT-23 surface-mount; 20 V ±5%; 500 mW PD; ZZT = 23 Ω @ 5 mA | Lower power, smaller footprint; unsuitable for >500 mW continuous dissipation | Choose for space-constrained PCBs where thermal management supports SMT mounting and power is ≤0.5 W |
Compared with 1N5932B and MMSZ5248BT1G, the 1N5932BRNG delivers higher surge robustness (98 W vs. 40 W typical for SOT-23), axial-leaded mechanical reliability for through-hole power stages, and guaranteed 3 W steady-state operation-making it optimal for industrial and automotive primary regulation where thermal mass and ruggedness are critical.

FAQ
What is the exact Zener voltage tolerance for the 1N5932BRNG?
The 1N5932BRNG has a Zener voltage tolerance of ±5%, with minimum, nominal, and maximum values specified as 19.00 V, 20.00 V, and 21.00 V respectively at IZT = 14 mA and TL = 30°C. This tolerance is guaranteed per device binning and applies across the full operating temperature range when derated per thermal curves in the datasheet.
Can the 1N5932BRNG be used in surface-mount designs?
No-the 1N5932BRNG is exclusively a through-hole axial-leaded device in DO-41 package (Case 59AB). It lacks surface-mount terminations or tape-and-reel packaging for SMT placement. For SMT alternatives, consider the MMSZ5248BT1G or SMAZ20A, but note their lower power ratings and different thermal behavior.
What is the maximum DC Zener current rating for the 1N5932BRNG?
The 1N5932BRNG has a maximum DC Zener current (IZM) of 75 mA, derived from its 3.0 W power rating and 20 V nominal Zener voltage (IZM = PD/VZ). This value assumes TL ≤ 75°C and proper lead heat sinking; operation above this current risks thermal runaway unless actively cooled.
Does the 1N5932BRNG meet RoHS requirements?
Yes-the "G" suffix in 1N5932BRNG explicitly denotes a Pb-free package compliant with EU RoHS Directive 2011/65/EU. The device uses matte tin-plated leads and halogen-free molding compound, and is qualified per J-STD-020 moisture sensitivity level (MSL) 1 for unlimited floor life.
How does the 1N5932BRNG handle repetitive surge events?
The 1N5932BRNG is rated for nonrepetitive 98 W surges at 1 ms, but repetitive surges require duty-cycle derating per Figure 2's transient thermal resistance curve. For example, at 1% duty cycle and 10 ms period, peak surge power must be reduced to ~20 W to avoid exceeding TJ = 200°C. Thermal design must account for cumulative heating across pulses.
