Product details
Overview
1N5934BRNG from onsemi is a 3 W, 24 V ±5% axial-lead Zener voltage regulator diode in DO-41 (Case 59AB) package, featuring 15.6 Ω max Zener impedance at 19 mA, 0.25 μA max reverse leakage at 18.2 V, and 98 W surge rating for 1 ms. It delivers stable reference voltage in power supply overvoltage clamping and voltage regulation circuits.
For engineers reviewing the 1N5934BRNG datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, thermal derating behavior, lead-to-ambient thermal resistance, polarity marking, and Pb-free compliance per JESD22-A114 Class 3 ESD rating.
Technical Context
The 1N5934BRNG operates as a silicon-oxide passivated junction Zener diode with precise 24 V nominal regulation at IZT = 19 mA. Its thermal performance is defined by junction-to-lead transient resistance (θJL) and steady-state power derating above 75°C at 24 mW/°C with 3/8″ lead length.
It supports non-repetitive surge pulses up to 98 W for 1 ms (Figure 3), exhibits <0.25 μA leakage at VR = 18.2 V, and maintains ±5% tolerance across −65°C to +200°C operating range. The cathode band denotes polarity, and soldering is rated at 260°C for 10 seconds at 1/16″ from case.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5934BRLG | Same electrical specs; tape-and-reel packaging (3000 pcs/reel) vs. bulk box (3000 pcs/box) | No functional difference; suited for automated SMT placement instead of manual/hand-soldered assembly | Select 1N5934BRLG when using pick-and-place equipment; identical thermal and electrical behavior |
| MMBZ5245BS | Surface-mount SOT-23 package; 24 V ±5%, but only 225 mW PD; ZZT = 30 Ω @ 10 mA | Not suitable for 3 W continuous dissipation; limited to low-power bias/reference use | Choose MMBZ5245BS only for space-constrained PCBs where power <0.25 W; not a drop-in replacement |
Compared with 1N5934BRNG, 1N5934BRLG offers identical regulation performance in automated assembly format, while MMBZ5245BS trades power handling for miniaturization-making it viable only in low-dissipation signal conditioning, not power rail clamping.

FAQ
What is the maximum steady-state power dissipation for 1N5934BRNG at 75°C lead temperature?
The 1N5934BRNG has a maximum steady-state power dissipation of 3.0 W at TL = 75°C with 3/8″ lead length. Above 75°C, it derates linearly at 24 mW/°C. This rating assumes proper heat sinking through leads and reflects the device's ability to sustain continuous Zener conduction without thermal runaway.
Does 1N5934BRNG meet RoHS and Pb-free requirements?
Yes, 1N5934BRNG is a certified Pb-free device compliant with RoHS Directive 2011/65/EU. The "G" suffix explicitly denotes Pb-free packaging, and the device uses silicon-oxide passivated junction technology compatible with standard lead-free soldering profiles up to 260°C for 10 seconds at 1/16″ from the case.
What is the reverse leakage current specification for 1N5934BRNG?
The 1N5934BRNG specifies a maximum reverse leakage current of 0.25 μA at VR = 18.2 V (85% of nominal VZ). This low leakage ensures minimal quiescent current draw in high-impedance reference networks and supports stable operation in battery-backed or energy-harvesting systems.
Can 1N5934BRNG be used as a direct replacement for older 1N5934B parts?
Yes, 1N5934BRNG is a direct form-fit-function replacement for 1N5934B, retaining identical electrical specifications, DO-41 package dimensions, and polarity marking. The "G" suffix adds Pb-free compliance without altering thermal, surge, or regulation performance-no PCB or schematic changes are required.
What is the Zener impedance of 1N5934BRNG and why does it matter?
The 1N5934BRNG has a maximum Zener impedance of 15.6 Ω at IZT = 19 mA. This value quantifies how tightly the device regulates voltage under varying current loads; lower ZZT means smaller output voltage deviation during load transients-critical for maintaining accuracy in feedback loops and reference circuits.
