Product details
Overview
ZGL41-180A-E3/97 from Vishay General Semiconductor is a surface-mount, glass-passivated Zener diode with nominal Zener voltage 180 V, 1.0 W power rating, and DO-213AB (GL41) plastic MELF package. It delivers low Zener impedance (900 Ω at 2.1 mA), low regulation factor, and operates up to +150 °C junction temperature. Used for precision voltage regulation and overvoltage protection in high-voltage DC power supplies.
For engineers reviewing the ZGL41-180A-E3/97 datasheet, ZGL41-180A-E3/97 pinout, ZGL41-180A-E3/97 application, or ZGL41-180A-E3/97 equivalent, key selection criteria include Zener voltage tolerance (±5 %), surge current capability (5.6 A), reverse leakage (1.0 μA at 136.9 V), thermal derating behavior, and MSL Level 1 reflow compatibility.
Technical Context
This device functions as a single-element, cathode-marked (red band), silicon-based voltage-regulating diode operating in reverse breakdown. Its glass-passivated junction ensures stable long-term Zener voltage and low IR drift, while the DO-213AB package enables automated placement and meets UL 94 V-0 flammability requirements.
The ZGL41-180A-E3/97 is characterized at 25 °C with IZT = 2.1 mA and exhibits a positive temperature coefficient of ~180 mV/°C near 180 V - confirmed by typical curves in the datasheet. It is rated for non-repetitive 8.3 ms surge current up to 5.6 A and supports steady-state dissipation of 1.0 W only when lead temperature TL ≤ 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 171–189 V at 2.1 mA test current; ±5 % tolerance band ensures predictable clamping in high-voltage reference circuits. |
| Total Power Dissipation (Ptot) | 1000 mW at TL = 75 °C; requires thermal management on PCB copper pads per specified 8 mm × 8 mm × 2 mm layout. |
| Zener Impedance (ZZT) | 900 Ω at IZT = 2.1 mA; low dynamic resistance improves regulation stability under varying load conditions. |
| Reverse Leakage (IR) | 1.0 μA maximum at VR = 136.9 V; enables low-power standby protection without significant quiescent drain. |
| Surge Current (IRM) | 5.6 A peak for 8.3 ms; handles transient overvoltage events such as inductive kickback or line surges. |
| Junction Temperature (TJ) | -55 °C to +150 °C operating range; supports deployment in industrial and automotive under-hood environments. |
Pinout & Package
Package: GL41 (DO-213AB) - cylindrical plastic MELF case with solderable matte tin-plated ends; red band denotes cathode (positive terminal in Zener configuration). Molding compound complies with UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (red band end) | Positive terminal in Zener operation | Connected to higher-potential node; reverse-biased to conduct regulation current into ground or return path. |
| Anode (unmarked end) | Negative terminal in Zener operation | Typically tied to system ground or low-side reference; completes current path during breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures long-term Zener voltage stability and low parameter drift over time and temperature cycling. |
| Low Zener impedance (900 Ω) | Minimizes output voltage variation under changing load current, critical for tight-tolerance reference designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-regulating diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5375BRLG | 180 V nominal, 5 W rating, DO-201AD package, higher ZZT (1200 Ω), wider VZ tolerance (±5 % same) | Higher power handling but larger footprint; less suitable for space-constrained SMT layouts | Select when >1 W continuous dissipation is required and board area permits axial/DIP-style mounting. |
| BZX85C180 | 180 V nominal, 1.3 W rating, DO-41 package, ZZT = 1000 Ω, MSL Level 1 not specified | Through-hole assembly only; no MELF automation support; lower surge rating (4.5 A) | Choose only for legacy through-hole designs where rework compatibility outweighs SMT efficiency. |
Compared with ZGL41-180A-E3/97, the 1N5375BRLG offers higher power but sacrifices SMT scalability, while the BZX85C180 lacks MELF process compatibility and delivers inferior surge robustness - making ZGL41-180A-E3/97 optimal for automated, high-reliability 180 V regulation in compact industrial systems.

FAQ
What is the Zener voltage tolerance of ZGL41-180A-E3/97?
ZGL41-180A-E3/97 has a Zener voltage range of 171 V to 189 V at 2.1 mA test current, representing a ±5 % tolerance about the nominal 180 V rating. This tolerance is verified per JEDEC test methods and applies under standard 25 °C conditions with specified IZT; actual VZ may shift predictably with temperature due to its positive tempco.
Does ZGL41-180A-E3/97 support lead-free reflow soldering?
Yes, ZGL41-180A-E3/97 meets MSL Level 1 per J-STD-020C and is qualified for lead-free reflow with a maximum peak temperature of 250 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, enabling direct use in standard Pb-free assembly lines without prebaking.
What is the maximum surge current rating for ZGL41-180A-E3/97?
ZGL41-180A-E3/97 is rated for a non-repetitive surge current of 5.6 A with 8.3 ms pulse width, per JEDEC test methodology. This rating assumes a square-wave or equivalent sine-wave waveform and is intended for transient overvoltage protection - not continuous operation.
How does the Zener impedance of ZGL41-180A-E3/97 affect regulation performance?
ZGL41-180A-E3/97 exhibits 900 Ω dynamic Zener impedance at 2.1 mA, directly influencing output voltage stability under load variation. Lower ZZT reduces ΔVZ for a given ΔIZ, improving regulation accuracy in feedback networks and reference circuits where tight voltage control is critical.
Is ZGL41-180A-E3/97 RoHS-compliant and halogen-free?
Yes, ZGL41-180A-E3/97 carries the "E3" suffix indicating full RoHS compliance per EU Directive 2011/65/EU. Vishay confirms this part meets material categorization requirements defined in document 99912, including absence of brominated flame retardants and halogen-free molding compound.
