Product details
Overview
1N5920BRL from onsemi is a 3 W, ±5% tolerance Zener diode with nominal zener voltage of 6.2 V, maximum zener impedance of 60.5 Ω at 2 mA test current, and surge rating of 98 W for 1 ms. It operates from −65 °C to +200 °C and is used in overvoltage protection, voltage reference, and DC power supply regulation circuits.
For engineers reviewing the 1N5920BRL datasheet, pinout, applications, or equivalent options, this device serves as a stable, Pb-free axial-lead voltage regulator in industrial power supplies, embedded system bias networks, and analog signal conditioning stages where precise 6.2 V clamping is required.
Technical Context
The 1N5920BRL uses a silicon-oxide passivated junction for stable reverse breakdown behavior and low leakage. Its thermal design relies on lead-to-ambient conduction (primary path through cathode lead), with derating starting at 75 °C for 3 W operation and at 50 °C for 1 W ambient-rated dissipation.
It exhibits a typical zener voltage temperature coefficient near zero for 6.2 V devices (per Figure 5), enabling minimal drift in reference applications. The 98 W surge capability supports transient suppression without requiring external snubbers in moderate-energy fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal (5.89–6.51 V min/max), defines precise clamping threshold in regulation circuits |
| Power Dissipation (PD) | 3 W at TL = 75 °C, enables compact thermal design with 3/8″ lead length to heatsink |
| Zener Impedance (ZZT) | 60.5 Ω max @ IZT = 2 mA, ensures low dynamic resistance for stable reference output |
| Surge Power | 98 W @ 1 ms nonrepetitive, supports transient overvoltage handling without failure |
| Leakage Current (IR) | 5 μA max @ VR = 5 V, minimizes standby power loss in high-impedance bias networks |
| ESD Rating | Class 3 (>16 kV HBM), provides robustness against handling-induced electrostatic discharge |
| Operating Temp | −65 °C to +200 °C, suitable for under-hood automotive, industrial control, and aerospace environments |
Pinout & Package
Package: DO-41 (Case 59), axial-lead, transfer-molded plastic, cathode indicated by band. Lead diameter uncontrolled within 0.71–0.86 mm; overall body length 4.10–5.20 mm, diameter 2.00–2.70 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased Zener terminal | Connected to higher potential node in regulation; carries full Zener current during conduction |
| Anode | Forward/anode reference terminal | Connected to lower potential (e.g., ground or return); establishes polarity for proper biasing |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free DO-41 package | Complies with RoHS; compatible with standard wave and reflow soldering (260 °C, 10 s at 1/16″ from case) |
| ±5% zener tolerance (B suffix) | Guarantees tight voltage window (5.89–6.51 V) without binning or post-selection |
| 60.5 Ω max ZZT @ 2 mA | Ensures <1% output variation across load current changes in precision reference designs |
| 98 W surge rating | Withstands common-line transients (e.g., ISO 7637-2 Pulse 1/2a) without derating or external TVS |
| Void-free thermosetting plastic case | Provides hermetic-level moisture resistance and mechanical stability in humid or vibration-prone environments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5920B | Same electrical specs, but in bulk box (2000 units) instead of tape-and-reel; no G suffix marking required for Pb-free compliance | Preferred for manual prototyping or low-volume hand-soldered assemblies where reel handling is unnecessary | Select 1N5920B when reel automation is not used and cost-per-unit optimization is secondary to ease of handling |
| BZX55C6V2 | 500 mW rating, 6.2 V ±5%, DO-35 package; significantly lower power and surge capability (40 W/1 ms) | Suitable only for low-power signal-level references, not for power rail regulation or surge suppression | Choose BZX55C6V2 only in space-constrained PCBs where 3 W dissipation is never required |
Compared with 1N5920BRL, the 1N5920B offers identical performance in non-automated builds, while BZX55C6V2 trades 83% lower power handling for smaller footprint-making 1N5920BRL the sole choice for robust 6.2 V regulation in industrial or automotive power domains.

FAQ
What is the zener voltage tolerance of the 1N5920BRL?
The 1N5920BRL has a ±5% zener voltage tolerance, confirmed by the "B" suffix in its part number and specified in the Electrical Characteristics table as 5.89 V (min) to 6.51 V (max) at IZT = 2 mA and TL = 30 °C. This tolerance is guaranteed across manufacturing lots and applies to all units shipped as 1N5920BRL.
Is the 1N5920BRL RoHS-compliant and Pb-free?
Yes, the 1N5920BRL is Pb-free and RoHS-compliant, as indicated by the "G" suffix in its full ordering code (1N5920BRL, G) and explicitly stated in the Mechanical Characteristics and Ordering Information sections of the datasheet. It meets JEDEC standards for lead-free soldering up to 260 °C for 10 seconds.
What is the maximum steady-state power dissipation for the 1N5920BRL at room temperature?
The 1N5920BRL is rated for 1 W steady-state power dissipation at TA = 50 °C, with derating of 6.67 mW/°C above that temperature. At TL = 75 °C (lead temperature), it delivers its full 3 W rating-making lead-to-heatsink thermal path critical for achieving rated power in the 1N5920BRL.
How does the 1N5920BRL perform under transient surge conditions?
The 1N5920BRL supports 98 W nonrepetitive surge power for 1 ms, as defined in the Maximum Ratings table and validated in Figure 3 of the datasheet. This capability allows it to absorb common automotive load-dump or inductive-switching transients without degradation, provided peak pulse duration remains ≤1 ms.
Can the 1N5920BRL be used as a replacement for the 1N4735A?
No-the 1N4735A is a 6.2 V, 1 W Zener in DO-41 with ±5% tolerance but only 40 W surge rating and higher ZZT (17 Ω typ). The 1N5920BRL delivers triple the power (3 W), 2.5× higher surge (98 W), and tighter impedance control-making it a functional upgrade, not a drop-in replacement, especially in thermally demanding applications.
