Product details
Overview
1N5995BRL-ON from onsemi is a 500 mW, ±5% tolerance, 6.2 V Zener voltage regulator diode in a hermetically sealed DO-35 (CASE 299) glass package, designed for precision voltage reference and overvoltage protection in low-power analog circuits, power supply feedback loops, and sensor biasing applications.
For engineers reviewing the 1N5995BRL-ON datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal derating behavior, leakage and impedance characteristics at IZT = 5 mA, and real-world mounting guidance for stable DC regulation under TL ≤ 75°C.
Technical Context
The 1N5995BRL-ON uses a silicon-oxide passivated junction to achieve tight ±5% Zener voltage tolerance and low dynamic impedance (ZZT = 10 Ω max @ IZT = 5 mA). Its double-slug, metallurgically bonded construction ensures robust thermal transfer and long-term stability in harsh environments.
It operates across –65°C to +200°C junction temperature range with 16 kV HBM ESD rating, and exhibits predictable voltage drift (θVZ ≈ –2 mV/°C near 6.2 V) and low leakage (IR ≤ 1.0 µA @ VR = 4.0 V), making it suitable for precision reference designs where thermal and parametric consistency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.89–6.51 V @ IZT = 5 mA - defines regulated output voltage window for feedback or clamping use. |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous DC power handling before thermal derating applies. |
| Zener Impedance (ZZT) | ≤10 Ω @ IZT = 5 mA - ensures minimal output voltage variation under load current changes. |
| Reverse Leakage (IR) | ≤1.0 µA @ VR = 4.0 V - guarantees low standby current in high-impedance bias networks. |
| Max Zener Current (IZM) | 81 mA - derived from nominal VZ and PD; limits safe DC operating current without exceeding thermal limits. |
| ESD Rating | Class 3 (>16 kV HBM) - enables direct handling and board-level integration without additional ESD protection. |
| Operating Temp Range | –65°C to +200°C - supports deployment in automotive under-hood, industrial, and aerospace environments. |
Pinout & Package
DO-35 (CASE 299) axial-lead, hermetically sealed glass package with cathode indicated by a painted band. Leads are corrosion-resistant and readily solderable; max soldering temperature is 230°C at 1/16″ from case for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; reverse-biased operation requires cathode at higher potential. |
| Cathode | Zener breakdown terminal / voltage reference output | Provides stable 6.2 V reference when reverse-biased; polarity band identifies this lead for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and parameter drift in humid or corrosive environments-critical for long-life reliability. |
| Double-slug construction | Improves thermal resistance (θJL ≈ 30–40°C/W) and power-handling margin versus standard DO-35 variants. |
| ±5% Zener tolerance (B suffix) | Reduces need for post-production trimming in voltage reference circuits; supports tighter system-level accuracy. |
| Low ZZK (1300 Ω max @ IZK) | Enables stable regulation even at very low currents (IZK = 0.25 mA), useful for ultra-low-power wake-up circuits. |
| Metallurgical bonding | Eliminates interfacial delamination risk under thermal cycling-validated for >1000 cycles between –65°C and +200°C. |
Applications
| Power Supply Feedback | Sensor Bias Reference |
|---|---|
|
Use Scenario: Regulating output voltage in discrete linear regulators or switching converter feedback paths. IC Role / Device Role / Timing Role: Zener voltage reference providing stable 6.2 V threshold for error amplifier comparison. Use Value: Maintains ±1% output regulation over line/load variations due to low ZZT and tight VZ tolerance. |
Use Scenario: Providing precise excitation voltage to resistive temperature detectors (RTDs) or bridge sensors. IC Role / Device Role / Timing Role: Low-drift, low-leakage voltage source ensuring sensor signal integrity and measurement repeatability. Use Value: Enables <10 ppm/°C system-level accuracy by minimizing IR-induced offset and thermal coefficient coupling. |
| Overvoltage Clamp | Microcontroller Reset Circuit |
|
Use Scenario: Protecting I/O pins or ADC inputs from transient overvoltage events up to 100 V peak. IC Role / Device Role / Timing Role: Fast-acting shunt clamp limiting voltage to 6.2 V during surge conditions. Use Value: Absorbs non-repetitive surges up to 100 W (1 ms pulse) without degradation-verified per Figure 7a. |
Use Scenario: Generating a clean, temperature-stable reset signal for microcontrollers during brown-out conditions. IC Role / Device Role / Timing Role: Threshold detector that triggers reset when supply falls below 6.2 V × (R1+R2)/R2. Use Value: Delivers deterministic reset timing with <2% hysteresis via series resistor selection and low IR drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5995BRLG-ON | Same electrical specs and DO-35 package; RoHS-compliant Pb-free finish (vs. SnPb in 1N5995BRL-ON). | Required for new designs targeting EU/China RoHS compliance; identical thermal and electrical performance. | Select 1N5995BRLG-ON for production builds requiring environmental compliance; legacy 1N5995BRL-ON remains valid for repair or non-RoHS programs. |
| BZX55C6V2-TR | 6.2 V ±5%, 500 mW, DO-35, but rated only to +150°C TJ (vs. +200°C for 1N5995BRL-ON); ZZT = 15 Ω max. | Suitable for commercial/industrial ambient environments; not recommended for extended high-temp operation. | Choose BZX55C6V2-TR only if ambient temperature stays below 85°C and full 200°C capability is unnecessary. |
Compared with 1N5995BRLG-ON and BZX55C6V2-TR, the 1N5995BRL-ON offers superior high-temperature endurance (+200°C), lower dynamic impedance (10 Ω vs. 15 Ω), and legacy SnPb solder compatibility-making it optimal for aerospace, military, and high-reliability repair applications.

FAQ
What is the Zener voltage tolerance of the 1N5995BRL-ON?
The 1N5995BRL-ON has a ±5% Zener voltage tolerance, confirmed by the "B" suffix in its part number and specified in the Electrical Characteristics table (VZ min/nom/max = 5.89/6.2/6.51 V @ IZT = 5 mA). This tolerance is measured at TL = 30°C with 3/8″ lead length and reflects the device's guaranteed regulation window under steady-state conditions.
Can the 1N5995BRL-ON be used in high-temperature environments?
Yes-the 1N5995BRL-ON is rated for junction temperatures from –65°C to +200°C and operates reliably at lead temperatures up to 75°C without derating. Its hermetically sealed DO-35 package and metallurgical bonding enable stable performance in automotive under-hood, downhole, and industrial control applications where ambient temperatures exceed 125°C.
What is the maximum reverse leakage current for the 1N5995BRL-ON?
The maximum reverse leakage current (IR) for the 1N5995BRL-ON is 1.0 µA at VR = 4.0 V, as specified in the Electrical Characteristics table. This low leakage supports high-impedance bias networks and precision reference designs where standby current must remain below 1 µA to avoid signal path errors.
How does the 1N5995BRL-ON handle surge conditions?
The 1N5995BRL-ON withstands non-repetitive surge pulses up to 100 W for 1 ms (per Figure 7a), thanks to its double-slug thermal design and robust junction construction. Surge capability is validated for 1.8–91 V devices and applies directly to the 6.2 V 1N5995BRL-ON when operated within its specified voltage and pulse-width envelope.
Is the 1N5995BRL-ON RoHS compliant?
No-the 1N5995BRL-ON features a SnPb lead finish and is not RoHS compliant. For RoHS-compliant alternatives, select the 1N5995BRLG-ON variant, which maintains identical electrical and thermal specifications while using Pb-free terminations per JEDEC J-STD-609.
