Product details
Overview
ZGL41-190A-E3/97 from Vishay General Semiconductor is a surface-mount, glass-passivated Zener diode in a GL41 (DO-213AB) MELF package, rated for 190 V nominal Zener voltage at 2.0 mA test current, 1.0 W total power dissipation, and 1.0 μA maximum reverse leakage at 144.4 V, used for precision voltage regulation and overvoltage protection in industrial power supplies and DC bus monitoring circuits.
For engineers reviewing the ZGL41-190A-E3/97 datasheet, ZGL41-190A-E3/97 pinout, ZGL41-190A-E3/97 application, or ZGL41-190A-E3/97 equivalent, key selection criteria include Zener voltage tolerance (±5.3%), dynamic impedance (1050 Ω at IZT), surge current rating (5.3 A), thermal stability up to +150 °C junction temperature, and RoHS-compliant matte tin-plated terminals solderable per J-STD-002.
Technical Context
This device operates as a single-element, unidirectional voltage-regulating diode with cathode denoted by a red band. Its glass-passivated junction ensures stable breakdown characteristics and low regulation factor across temperature, while the DO-213AB package supports automated placement and meets MSL Level 1 with peak reflow of 250 °C.
The ZGL41-190A-E3/97 delivers 190 V nominal regulation with ±5.3% tolerance (180–200 V range), specified at 2.0 mA test current and 0.25 mA knee current. It exhibits 1050 Ω dynamic impedance at IZT and 7500 Ω at IZK, enabling predictable clamping behavior under transient and low-current conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 190 V nominal, 180–200 V range at 2.0 mA - defines precise clamping threshold for 190 V rail protection |
| Total Power Dissipation (Ptot) | 1.0 W at TL = 75 °C - sets thermal derating limit for PCB copper pad layout |
| Zener Impedance (ZZT) | 1050 Ω at IZT = 2.0 mA - determines regulation sensitivity to load current variation |
| Reverse Leakage (IR) | 1.0 μA max at VR = 144.4 V - ensures minimal standby power loss in high-impedance bias networks |
| Surge Current (IRM) | 5.3 A, 8.3 ms non-repetitive - validates robustness against line transients per JEDEC method |
| Junction Temperature (TJ) | -55 to +150 °C - enables operation in extended-temperature industrial environments |
Pinout & Package
Package: GL41 (DO-213AB) - cylindrical plastic MELF case with solderable matte tin-plated ends; red band denotes cathode (positive terminal); polarity-critical for correct orientation in series-shunt regulation paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward bias | Connected to lower-potential node; must be held ≤ 0.76 V below cathode to avoid conduction |
| Cathode | Current exit point during Zener breakdown | Marked with red band; connected to regulated/high-side node; defines 190 V reference potential |
Key Features
| Feature | Design Value |
|---|---|
| Low Zener impedance | 1050 Ω at 2.0 mA - minimizes output voltage deviation under varying load currents |
| Glass-passivated chip junction | Stable breakdown voltage with <±0.05 %/°C tempco - reduces drift in temperature-critical sensing |
| MSL Level 1 rating | Peak reflow ≤ 250 °C - supports standard lead-free SMT assembly without moisture-related popcorning |
| UL 94 V-0 molding compound | Flame-retardant encapsulation - satisfies safety requirements for enclosed industrial power modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-regulating diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4749A-T | 24 V Zener, 1.0 W, DO-41 package - lower voltage, axial lead, higher ZZT (20 Ω) | Not suitable for 190 V systems; limited to low-voltage regulator references | Select only when 24 V regulation and through-hole mounting are required |
| BZX85C180 | 180 V Zener, 1.3 W, DO-41 - 10 V lower nominal VZ, 10% wider tolerance (±10%), higher Ptot | Acceptable for less stringent 180 V clamping where ±10 V margin is allowed | Choose if cost sensitivity outweighs 190 V precision and MELF SMT compatibility |

This tight tolerance ensures predictable clamping behavior in precision regulation applications such as feedback references for 190 V power supplies.
Does the ZGL41-190A-E3/97 support lead-free reflow soldering?
Yes, the ZGL41-190A-E3/97 meets MSL Level 1 per J-STD-020C with a maximum peak reflow temperature of 250 °C, making it fully compatible with standard lead-free SMT processes. Its matte tin-plated terminals are solderable per J-STD-002 and JESD 22-B102, ensuring reliable joint formation without whisker risk (M3 suffix compliant).
What is the maximum surge current rating for the ZGL41-190A-E3/97?
The ZGL41-190A-E3/97 is rated for a maximum non-repetitive surge current of 5.3 A with an 8.3 ms pulse width, per JEDEC test method. This rating validates its ability to absorb transient energy in DC bus protection applications without degradation, provided pulse duty cycle remains ≤1%.
How does the ZGL41-190A-E3/97 differ from standard DO-41 Zener diodes?
The ZGL41-190A-E3/97 uses a GL41 (DO-213AB) MELF package instead of DO-41, offering superior thermal dissipation, automated placement compatibility, and tighter dimensional control. Its glass-passivated junction also delivers lower Zener impedance (1050 Ω vs. typical 2000+ Ω) and improved long-term stability compared to epoxy-encapsulated DO-41 variants.
Is the ZGL41-190A-E3/97 RoHS-compliant?
Yes, the ZGL41-190A-E3/97 is RoHS-compliant per EU Directive 2011/65/EU, indicated by the "E3" suffix in the part number. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and conforms to Vishay's material categorization standard documented in www.vishay.com/doc?99912.
