Product details
Overview
1N5923BRL from onsemi is a 3 W, ±5% tolerance Zener diode in DO-41 (Case 59) axial package, with nominal Zener voltage of 8.2 V at 3.5 mA test current, maximum Zener impedance of 45.7 Ω at IZT, and reverse leakage current ≤0.5 μA at 6.5 V. It delivers stable voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the 1N5923BRL datasheet, pinout, applications, or equivalent options, key selection criteria include its 8.2 V nominal Zener voltage, 3 W steady-state power rating at TL = 75°C, DO-41 mechanical compatibility, and Pb-free tape-and-reel packaging (6000 units/reel).
Technical Context
This device operates as a silicon-oxide passivated junction Zener regulator, optimized for stable DC voltage reference and clamping. Its electrical behavior is defined at TL = 30°C with guaranteed limits on VZ, ZZT, ZZK, IR, IZM, and VF - six parameters fully specified per ON Semiconductor's production testing.
The 1N5923BRL exhibits a negative temperature coefficient below ~5 V and transitions toward zero/near-zero coefficient near 8.2 V, minimizing drift in mid-voltage references. Its surge capability is rated at 98 W for 1 ms non-repetitive pulses, supporting transient suppression in power supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 8.2 V at IZT = 3.5 mA - defines primary regulation point for precision biasing |
| Zener Impedance (ZZT) | 45.7 Ω max at IZT - determines AC regulation sensitivity and ripple rejection |
| Max Steady-State Power (PD) | 3 W at TL = 75°C - sets thermal design limit with 24 mW/°C derating above 75°C |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 6.5 V - ensures minimal quiescent current in high-impedance sensing nodes |
| Surge Power Rating | 98 W @ 1 ms - supports short-duration overvoltage transients without degradation |
| ESD Rating | Class 3 (>16 kV HBM) - enables robust handling in manual assembly and field service |
| Package | DO-41 (Case 59), axial lead, Pb-free - compatible with legacy through-hole PCB layouts and automated insertion |
Pinout & Package
Package: DO-41 (Case 59), axial-leaded plastic, void-free transfer-molded thermosetting body. Cathode identified by black polarity band. Leads are corrosion-resistant and readily solderable at 260°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener breakdown terminal | Connected to regulated output node; reverse-biased operation requires cathode at higher potential than anode |
| Anode | Reference return path | Typically tied to ground or common rail; completes current path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Guaranteed VZ range of 7.79–8.61 V enables tight regulation without post-production trimming |
| 3 W power dissipation in DO-41 | Delivers 3× the power of standard 1 W Zeners in same footprint, reducing board space vs. parallel devices |
| ESD robustness >16 kV HBM | Eliminates need for external ESD protection in low-speed interface and sensor signal conditioning |
| Low leakage ≤0.5 μA | Maintains accuracy in high-impedance voltage divider networks and battery-powered monitoring circuits |
| Pb-free tape-and-reel packaging | Enables RoHS-compliant SMT-compatible assembly via axial tape feeders (6000/reel) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5923B | Same electrical specs; bulk-packaged (2000/box), not tape-and-reel | Lacks automated assembly support; suitable for hand-solder or wave-solder prototyping | Select 1N5923BRL for SMT line integration; choose 1N5923B for low-volume manual assembly |
| BZX55C8V2 | 5% tolerance, 500 mW rating, DO-35 package; lower power, smaller footprint | Insufficient for 3 W continuous dissipation; limited to <100 mA Zener current | Use BZX55C8V2 only where power demand is <0.5 W and board space is constrained |
Compared with 1N5923B (bulk) and BZX55C8V2 (low-power DO-35), the 1N5923BRL uniquely combines 3 W capability, DO-41 mechanical compatibility, and tape-and-reel automation readiness - making it optimal for volume production of industrial power supplies and sensor interfaces requiring robust 8.2 V regulation.

FAQ
What is the nominal Zener voltage and test current for the 1N5923BRL?
The 1N5923BRL has a nominal Zener voltage of 8.2 V, measured at a test current (IZT) of 3.5 mA under controlled lead temperature conditions (TL = 30°C). This value falls within the guaranteed range of 7.79 V to 8.61 V at ±5% tolerance, as specified in the ON Semiconductor datasheet Rev. 9 (July 2024).
Does the 1N5923BRL support automated assembly processes?
Yes, the 1N5923BRL is supplied in Pb-free tape-and-reel format (6000 units per reel), fully compatible with axial lead auto-insertion equipment and pick-and-place feeders configured for DO-41 packages. Its standardized marking and polarity band enable reliable optical orientation detection during placement.
How does the 1N5923BRL handle thermal derating above ambient temperature?
The 1N5923BRL derates at 24 mW/°C above TL = 75°C for steady-state operation with 3/8″ lead length. At TA = 50°C, its power dissipation is limited to 1 W with 6.67 mW/°C derating above that point. Thermal performance depends on mounting method - direct heatsinking improves dissipation, while free-air operation follows published derating curves.
What is the maximum reverse leakage current specification for the 1N5923BRL?
The 1N5923BRL specifies a maximum reverse leakage current (IR) of 0.5 μA when biased at VR = 6.5 V, measured at TL = 30°C. This low leakage supports high-impedance circuit applications such as precision voltage dividers and battery-monitoring inputs where standby current must remain sub-microamp.
Is the 1N5923BRL suitable for surge protection applications?
The 1N5923BRL is rated for 98 W non-repetitive surge power at 1 ms pulse width, making it suitable for clamping moderate-energy transients in DC power rails and signal lines. However, it is not intended as a primary surge protector like dedicated TVS diodes; use it for secondary clamping where fast response and low clamping voltage are required alongside stable DC regulation.
