Product details
Overview
ZGL41-190A-E3/96 from Vishay General Semiconductor is a surface-mount, glass-passivated Zener diode in a plastic MELF (DO-213AB) 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-DC converter feedback loops.
For engineers reviewing the ZGL41-190A-E3/96 datasheet, ZGL41-190A-E3/96 pinout, ZGL41-190A-E3/96 application, or ZGL41-190A-E3/96 equivalent, key selection criteria include Zener voltage tolerance (±5.3%), dynamic impedance (1050 Ω at IZT), junction temperature range (–55 °C to +150 °C), surge current rating (5.3 A), and RoHS-compliant matte tin-plated terminals solderable per J-STD-002.
Technical Context
This device operates as a single-element, cathode-marked (red band) voltage-regulating diode with a glass-passivated silicon junction, designed for stable DC reference and clamping in high-reliability linear and switching power circuits where low regulation factor and low Zener impedance are critical.
It delivers specified Zener behavior under pulsed test conditions (8.3 ms surge, 250 °C peak reflow), meets MSL Level 1 per J-STD-020C, and maintains regulation across –55 °C to +150 °C operating junction temperature with a positive temperature coefficient of ~180 mV/°C at 190 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 180 V min / 190 V nom / 200 V max at IZT = 2.0 mA - defines tight regulation window for feedback sensing accuracy |
| Total Power Dissipation (Ptot) | 1000 mW at TL = 75 °C - sets thermal derating limit for PCB copper pad layout design |
| Zener Impedance (ZZT) | 1050 Ω max at IZT = 2.0 mA - determines AC ripple rejection capability in regulation circuits |
| Reverse Leakage (IR) | 1.0 μA max at VR = 144.4 V - ensures minimal quiescent current loss in high-impedance bias networks |
| Surge Current (IRM) | 5.3 A max (8.3 ms pulse) - defines transient overvoltage clamping capacity without failure |
| Junction Temp Range (TJ) | –55 °C to +150 °C - enables operation in automotive under-hood and industrial motor drive environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-regulating diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5275B-TAP | 190 V nominal, 500 mW Ptot, DO-35 package, 1500 Ω ZZT | Lower power rating limits use to sub-500 mW designs; axial lead form requires manual assembly or through-hole conversion | Select when cost sensitivity outweighs power density and SMT compatibility requirements |
| BZX85C190 | 190 V nominal, 1.3 W Ptot, DO-41 package, 1200 Ω ZZT, 2 μA IR | Larger DO-41 body increases PCB footprint; higher leakage reduces suitability for ultra-low-power bias networks | Prefer for legacy board redesigns where DO-41 footprint exists and thermal margin exceeds 1.0 W |
Compared with ZGL41-190A-E3/96, the 1N5275B-TAP offers lower cost but sacrifices 50% power handling and SMT automation support, while the BZX85C190 provides higher power margin at the expense of larger size and doubled reverse leakage-making ZGL41-190A-E3/96 optimal for space-constrained, high-reliability SMT power regulation.

FAQ
What is the Zener voltage tolerance of ZGL41-190A-E3/96?
ZGL41-190A-E3/96 has a Zener voltage range of 180 V (minimum) to 200 V (maximum) at 2.0 mA test current, yielding a ±5.3% tolerance around the nominal 190 V rating. This tolerance is guaranteed across the full operating temperature range and reflects the device's specification per Vishay Document Number 88409, Revision 19-Feb-18. The ZGL41-190A-E3/96 achieves this stability via glass-passivated junction construction and tight process control.
Does ZGL41-190A-E3/96 support lead-free reflow soldering?
Yes, ZGL41-190A-E3/96 is qualified for lead-free reflow soldering per J-STD-020C, with a maximum peak temperature of 250 °C and MSL Level 1 classification-meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards. The ZGL41-190A-E3/96's DO-213AB package is fully compatible with standard 7" tape-and-reel SMT lines.
What is the maximum surge current rating for ZGL41-190A-E3/96?
ZGL41-190A-E3/96 has a maximum non-repetitive surge current (IRM) of 5.3 A for an 8.3 ms pulse width, per JEDEC test method. This rating applies to single-event transients such as inductive kickback or lightning-induced surges in power supply inputs. The ZGL41-190A-E3/96 maintains structural integrity and electrical parameters after such events when operated within its specified junction temperature limits.
How does the Zener impedance of ZGL41-190A-E3/96 affect regulation performance?
ZGL41-190A-E3/96 exhibits a maximum dynamic Zener impedance (ZZT) of 1050 Ω at 2.0 mA test current, directly impacting its ability to reject AC ripple and maintain stable output voltage under varying load conditions. Lower impedance yields tighter regulation-this value enables <1% output deviation for ±10% load current shifts in typical feedback networks. The ZGL41-190A-E3/96's glass-passivated junction contributes to consistent ZZT across temperature and lifetime.
Is ZGL41-190A-E3/96 RoHS-compliant and halogen-free?
Yes, ZGL41-190A-E3/96 carries the "E3" suffix indicating full RoHS compliance per EU Directive 2011/65/EU and Vishay's material categorization standard (Document 99912). Its molding compound meets UL 94 V-0 flammability rating and contains no halogens above threshold limits. The ZGL41-190A-E3/96 is also compliant with JEDEC JESD201 Class 1A whisker testing when ordered with the "M3" suffix, though E3/96 uses standard matte tin plating.
