Product details
Overview
1N5952BRLG from onsemi is a 3 W, 130 V ±5% Zener diode in DO-41 axial package, designed for precision voltage regulation and overvoltage protection in DC power rails. It delivers stable clamping at IZT = 450 mA with ZZT = 2.9 Ω, supports 98 W surge (1 ms), and operates across −65°C to +200°C.
For engineers reviewing the 1N5952BRLG datasheet, pinout, applications, or equivalent options, this device serves as a high-voltage, high-survivability Zener regulator in industrial power supplies, telecom line cards, and automotive body control modules where thermal robustness and ESD immunity (>16 kV HBM) are critical.
Technical Context
This Zener diode uses silicon-oxide passivated junction technology to achieve tight voltage tolerance (±5%), low dynamic impedance, and stable regulation under varying load and temperature conditions. Its 3 W steady-state dissipation at TL = 75°C and 98 W non-repetitive surge rating enable reliable operation in transient-prone environments.
The device features cathode polarity marking, Pb-free DO-41 plastic package (Case 59), and guaranteed limits on six electrical parameters including VZ, IZM, ZZT, ZZK, IR, and VF. Thermal resistance is lead-length dependent, with θJL = 25°C/W typical at 3/8″ lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 123.5 V min / 130 V nominal / 136.5 V max @ IZT = 450 mA - defines precise clamping threshold for 130 V rail protection |
| Max DC Zener Current (IZM) | 98.8 A - sets absolute upper current limit before thermal runaway at rated power |
| Zener Impedance (ZZT) | 2.9 Ω @ IZT = 450 mA - ensures minimal voltage shift under load variation, critical for regulation accuracy |
| Surge Power Rating | 98 W @ 1 ms - enables survival of short-duration transients like ISO 7637-2 pulse 1/2a in automotive systems |
| ESD Rating | Class 3 (>16 kV) per HBM - eliminates need for external ESD protection in handling and board-level assembly |
| Operating Temperature | −65°C to +200°C - supports deployment in under-hood automotive, downhole, and industrial ambient extremes |
| Package | DO-41 (Case 59), axial lead, Pb-free - compatible with standard through-hole insertion and wave soldering at 260°C for 10 s |
Pinout & Package
DO-41 plastic axial package (Case 59, Style 1), void-free transfer-molded thermosetting plastic body with corrosion-resistant leads. Cathode indicated by black band; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener breakdown terminal | Connected to regulated voltage node; reverse-biased during regulation; carries full IZ current |
| Anode (unbanded end) | Reference/return terminal | Connected to circuit ground or lower-potential rail; completes Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Guaranteed VZ window (123.5–136.5 V) reduces need for post-production trimming in high-voltage reference designs |
| 2.9 Ω dynamic impedance | Minimizes output voltage deviation (< ±0.3 V) across ±100 mA load current changes at nominal regulation point |
| 98 W 1 ms surge capability | Withstands automotive load-dump transients without degradation, eliminating need for parallel TVS in many 24 V systems |
| Class 3 ESD immunity | Eliminates pre-assembly ESD handling controls and downstream protection components in manufacturing flow |
| −65°C to +200°C operating range | Enables single-part qualification across engine bay, powertrain, and industrial motor drive applications without derating penalties |
Applications
| Industrial Power Supply Protection | Automotive Load-Dump Clamping |
|---|---|
Use Scenario: 130 V intermediate bus in programmable logic controller (PLC) power stage exposed to switching transients and lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp protecting downstream DC-DC converters and microcontrollers from >150 V spikes. Use Value: 98 W surge rating absorbs 1 ms transients without failure; ±5% VZ ensures consistent trip point across production lots. |
Use Scenario: 24 V vehicle electrical system subjected to ISO 7637-2 Pulse 5a (load dump) up to 120 V for 400 ms. IC Role / Device Role / Timing Role: Standby shunt regulator that conducts only during overvoltage events, minimizing quiescent loss. Use Value: 130 V nominal VZ provides 10 V margin above peak load-dump voltage while maintaining safe headroom below MOSFET drain ratings. |
| Telecom Line Card Voltage Reference | High-Voltage Sensor Biasing |
Use Scenario: Precision analog front-end in optical line terminal (OLT) requiring stable 130 V bias for avalanche photodiode (APD) operation. IC Role / Device Role / Timing Role: Low-noise, low-drift voltage reference source supplying constant bias current via series resistor. Use Value: 2.9 Ω ZZT and <0.25 μA leakage at 100 V ensure sub-1 mV ripple and negligible current error in APD gain control loop. |
Use Scenario: High-side current sensing in 100–150 V industrial motor drive using isolated amplifier with internal Zener reference. IC Role / Device Role / Timing Role: Local voltage reference for isolated gate driver ICs and analog-to-digital converter (ADC) bias networks. Use Value: −65°C to +200°C rating allows placement near heat-generating IGBT modules without drift or failure; Pb-free DO-41 simplifies RoHS-compliant rework. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5952BRL | Same electrical specs and DO-41 package; differs only in Pb-free plating (G suffix denotes Pb-free, RLG = Pb-free tape-and-reel) | No functional difference; identical performance in all circuits | Select 1N5952BRLG when RoHS compliance and tape-and-reel automation are required |
| SMF130A | Surface-mount SOD-123 package; 130 V, 200 W peak power, but only 1 W steady-state rating and higher ZZT (≈10 Ω) | Suitable for space-constrained PCBs but not for continuous 3 W dissipation or high-current regulation | Choose SMF130A only for low-duty-cycle transient suppression where board area is premium and average power <0.5 W |
Compared with 1N5952BRLG, the 1N5952BRL offers identical performance in Pb-containing assembly processes, while SMF130A trades package size and surge capacity for reduced thermal mass and lower continuous power handling-making it unsuitable as a direct replacement in 3 W regulation roles.

FAQ
What is the Zener voltage tolerance of the 1N5952BRLG?
The 1N5952BRLG has a Zener voltage tolerance of ±5%, with a guaranteed range of 123.5 V (min) to 136.5 V (max) at test current IZT = 450 mA. This tight tolerance is specified per onsemi's 1N5913B Series datasheet Rev. 9 and applies to all units bearing the "B" suffix, ensuring consistent clamping behavior across production batches without calibration.
Can the 1N5952BRLG be used in surface-mount designs?
No, the 1N5952BRLG is packaged exclusively in the axial-leaded DO-41 (Case 59) format and is not available in surface-mount variants. It requires through-hole mounting and wave or selective soldering. For SMT alternatives, consider the SMF130A (SOD-123), though it offers only 1 W steady-state power and higher dynamic impedance versus the 1N5952BRLG.
What is the maximum surge power the 1N5952BRLG can withstand?
The 1N5952BRLG is rated for 98 W non-repetitive surge power at 1 ms pulse width, as confirmed in the Absolute Maximum Ratings table of the onsemi datasheet. This rating is validated under specified test conditions (TJ = 25°C prior to pulse) and must not be exceeded, as Figure 3 explicitly states surge limitations are lower than those predicted by thermal resistance alone due to localized current crowding effects.
How does the 1N5952BRLG handle high-temperature environments?
The 1N5952BRLG operates across −65°C to +200°C, with steady-state power derated linearly above 75°C (24 mW/°C) when lead length is 3/8″. Its silicon-oxide passivated junction and thermosetting plastic package maintain parameter stability and mechanical integrity in under-hood automotive or industrial motor drive environments where ambient temperatures exceed 125°C.
Is the 1N5952BRLG RoHS compliant?
Yes, the "G" suffix in 1N5952BRLG explicitly indicates a Pb-free package per onsemi's ordering nomenclature. The device meets RoHS Directive 2011/65/EU requirements, with lead-free plating on axial leads and halogen-free molding compound, as documented in the "ORDERING INFORMATION" and "Mechanical Characteristics" sections of the official datasheet.
