Product details
Overview
1N6025CRL from ON Semiconductor (formerly Motorola) is a 110 V ±2% precision Zener voltage regulator diode in DO-35 glass package, rated for 500 mW DC power dissipation at TL ≤ 75°C, with 650 Ω maximum zener impedance at 1 mA test current and 0.1 µA reverse leakage at 1 V. It serves as a stable reference in low-power analog circuits, overvoltage clamping networks, and feedback regulation stages.
For engineers reviewing the 1N6025CRL datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal derating behavior, JEDEC-compliant zener impedance and leakage data, and real-world substitution guidance - all confirmed against Motorola's original 500 mW DO-35 Glass Technical Data (6-108).
Technical Context
This device operates in reverse-biased breakdown mode, delivering a tightly regulated 110 V nominal output with ±2% tolerance ('C' suffix), measured at IZT = 1 mA and lead temperature of 30°C ±1°C. Its double-slug, hermetically sealed DO-35 glass construction ensures stable long-term voltage reference performance under thermal cycling.
The 1N6025CRL exhibits a positive temperature coefficient of +0.11 %/°C (typical), confirmed per Motorola's JEDEC-registered characterization across 25–125°C, and supports surge power up to 47 W for 1 ms pulses (non-repetitive, 100–200 V range), per Figure 7b.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 110 V ±2% (C-grade tolerance), measured at IZT = 1 mA, TL = 30°C - enables precise high-voltage reference design |
| Power Dissipation | 500 mW at TL ≤ 75°C; derates linearly to zero at 150°C - defines maximum continuous biasing capability |
| Zener Impedance | 650 Ω max at IZT = 1 mA, f = 1 kHz - indicates regulation stability under small-signal load variations |
| Reverse Leakage | 0.1 µA max at VR = 1 V, TA = 25°C - ensures minimal quiescent current in standby clamp circuits |
| Operating Temperature | –65°C to +200°C junction/storage range - suitable for industrial and automotive under-hood environments |
| Package | DO-35 (CASE 299, DO-204AH) glass body with axial leads - compatible with through-hole wave soldering and manual rework |
| Forward Voltage | 1.5 V max at IF = 100 mA - confirms standard silicon PN junction behavior for bidirectional protection use cases |
Pinout & Package
DO-35 glass package: axial-leaded, hermetically sealed double-slug construction. Cathode indicated by color band; anode is unmarked lead. Leads are corrosion-resistant and readily solderable. Maximum soldering temperature: 230°C at 1/16″ from case for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded lead) | Reference ground node in zener configuration | Connected to circuit common; reverse-bias polarity must be observed for regulation |
| Cathode (banded lead) | Regulated output node in zener configuration | Provides stable 110 V relative to anode when reverse-biased above breakdown threshold |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79C110RL | Same 110 V ±2%, DO-35 package, but 500 mW rating with 650 Ω ZZT @ 1 mA - identical core specs | Identical thermal and electrical performance; widely stocked in European distribution channels | Drop-in replacement with same footprint, polarity, and JEDEC compliance; preferred for EU-based BOMs |
| 1N5272B | 110 V ±5% ('B' suffix), DO-35, 500 mW, 750 Ω ZZT @ 1 mA - looser tolerance and higher impedance | Suitable where cost sensitivity outweighs precision; not recommended for closed-loop feedback | Select only if ±5% voltage drift is acceptable and system-level calibration compensates for impedance variation |
Compared with 1N6025CRL, BZX79C110RL offers identical performance and direct compatibility, while 1N5272B trades precision and regulation stiffness for lower unit cost - making the former ideal for high-accuracy designs and the latter appropriate for non-critical clamping.

FAQ
What is the exact Zener voltage tolerance and test condition for 1N6025CRL?
The 1N6025CRL has a ±2% Zener voltage tolerance (denoted by the 'C' suffix), with nominal 110 V specified at IZT = 1 mA and lead temperature of 30°C ±1°C using a 3/8″ lead length. This matches Motorola's JEDEC-registered test methodology documented in Technical Data Sheet 6-108.
Can 1N6025CRL be used in surface-mount designs?
No - the 1N6025CRL is packaged exclusively in the axial-leaded DO-35 (CASE 299) glass package and is not available in SMD variants. It requires through-hole mounting; no compatible SMT equivalent shares identical electrical specs and thermal profile.
What is the maximum allowable surge power for 1N6025CRL?
Per Figure 7b of the Motorola 500 mW DO-35 Glass datasheet, the 1N6025CRL supports up to 47 W peak surge power for 1 ms duration (non-repetitive, rectangular waveform, TJ = 25°C prior to pulse), applicable to the 100–200 V Zener voltage range.
How does temperature affect the Zener voltage of 1N6025CRL?
The 1N6025CRL exhibits a typical temperature coefficient of +0.11 %/°C, meaning its Zener voltage increases by approximately 121 mV per °C rise across the 25–125°C range. This value is confirmed in Motorola's JEDEC characterization (1N5272B series, which shares identical VZ and tempco behavior).
Is 1N6025CRL RoHS compliant and halogen-free?
Yes - as a legacy ON Semiconductor part derived from Motorola's DO-35 Zener family, the 1N6025CRL meets RoHS Directive 2011/65/EU and is manufactured without brominated flame retardants or chlorine-based compounds, consistent with ON Semi's material declarations for glass-passivated discrete diodes.
