Product details
Overview
1N5929BRNG from onsemi is a 15 V ±5% Zener voltage regulator diode in DO-41 axial package, rated for 3 W steady-state power dissipation at 75°C lead temperature, with 25 Ω maximum Zener impedance at 25 mA test current and 0.25 μA reverse leakage at 11.4 V. It serves as a precision voltage reference in low-power linear regulators and overvoltage protection circuits.
For engineers reviewing the 1N5929BRNG datasheet, pinout, applications, or equivalent options, key selection criteria include its ±5% tolerance, 98 W surge rating at 1 ms, Class 3 ESD immunity (>16 kV HBM), Pb-free Surmetic 30 construction, and thermal derating behavior above 75°C.
Technical Context
The 1N5929BRNG operates as a silicon-oxide passivated junction Zener diode, optimized for stable reverse-biased regulation at nominal 15 V. Its electrical behavior is defined by two critical test points: IZT = 25 mA (for VZ and ZZT) and IZK = 9 mA (for ZZK and VR), with guaranteed limits across six parameters including VZ, ZZT, ZZK, IR, VF, and IZM.
Thermal performance is lead-temperature dependent: steady-state dissipation drops linearly from 3.0 W at TL = 75°C to zero at TL = 195°C, while surge capability follows a non-repetitive rectangular pulse profile peaking at 98 W for 1 ms. Polarity is marked by a cathode band; mounting position is unrestricted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.25–15.75 V @ IZT = 25 mA - defines regulated output range under standard test conditions |
| Zener Impedance (ZZT) | 25 Ω max @ IZT = 25 mA - determines AC regulation error under dynamic load changes |
| Reverse Leakage (IR) | 0.25 μA max @ VR = 11.4 V - ensures minimal quiescent current in standby protection circuits |
| Surge Power | 98 W @ 1 ms non-repetitive - supports transient overvoltage clamping without failure |
| ESD Rating | Class 3 (>16 kV HBM) - enables robust handling in automated assembly and field service |
| Package | DO-41 (Case 59AB), axial lead, Pb-free - compatible with legacy through-hole PCB layouts and wave soldering |
| Steady-State Power | 3.0 W @ TL = 75°C, derated 24 mW/°C above - sets maximum continuous dissipation based on heatsinking |
Pinout & Package
DO-41 (Case 59AB) axial-leaded plastic package with cathode indicated by a single color band. Body dimensions: 4.10–5.20 mm length × 2.00–2.70 mm diameter; lead diameter 0.71–0.86 mm; lead length uncontrolled beyond 13.7 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to circuit node requiring stabilized voltage; reverse-biased during regulation |
| Anode | Reference return path | Typically tied to ground or lower-potential rail; completes current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Silicon-oxide passivated junction | Enables stable long-term VZ drift and high reliability in humid or industrial environments |
| Surmetic 30 construction | Provides hermetic-level moisture resistance without glass or metal packaging |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5929BRLG | Same electrical specs; surface-mount SOD-123 package instead of DO-41 | Requires PCB redesign for SMT assembly; no axial leads for manual prototyping | Select when board space is constrained and automated placement is available |
| MMBZ5245BS | 15 V, ±5%, but rated only for 225 mW; SOT-23 package; higher ZZT (30 Ω) | Limited to low-power signal referencing; unsuitable for >10 mA regulation loads | Select only for ultra-low-power biasing where 3 W capability is unnecessary |
Compared with 1N5929BRNG, the 1N5929BRLG offers identical regulation performance in a compact SMT form factor, while the MMBZ5245BS trades power handling and thermal robustness for miniaturization-making 1N5929BRNG the preferred choice for through-hole, medium-power, and surge-prone applications.

FAQ
What is the Zener voltage tolerance of the 1N5929BRNG?
The 1N5929BRNG has a Zener voltage tolerance of ±5%, as indicated by the "B" suffix in its part number. Its specified VZ range is 14.25 V to 15.75 V at IZT = 25 mA and TL = 30°C. This tolerance is guaranteed across the full operating temperature range and applies to all units shipped, supporting predictable performance in production designs without binning.
Can the 1N5929BRNG be used in surface-mount designs?
No-the 1N5929BRNG uses a DO-41 axial-leaded package (Case 59AB) and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N5929BRLG in SOD-123 or MMBZ5245BS in SOT-23. The 1N5929BRNG requires through-hole mounting with 3/8″ lead length to heat sink for rated 3 W operation.
What is the maximum surge power rating for the 1N5929BRNG?
The 1N5929BRNG is rated for 98 W non-repetitive surge power at 1 ms pulse width, per Figure 3 in the official datasheet. This rating assumes TJ = 25°C prior to the pulse and applies only to single, isolated transients-not repetitive events. Exceeding this limit risks irreversible junction damage.
How does thermal derating work for the 1N5929BRNG?
The 1N5929BRNG's steady-state power dissipation derates linearly above 75°C lead temperature: PD = 3.0 W − [(TL − 75) × 0.024 W/°C]. At TL = 100°C, it delivers 2.4 W; at TL = 150°C, 1.2 W. Derating is based on measured lead temperature-not ambient-so proper heatsinking or clip mounting is essential for sustained high-power operation.
Is the 1N5929BRNG RoHS-compliant and halogen-free?
Yes-the "G" suffix in 1N5929BRNG explicitly denotes a Pb-free, RoHS-compliant package. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and contains no halogenated flame retardants, as confirmed in onsemi's material declarations and packaging specification BRD8011/D.
