Product details
Overview
GLL4759A-E3/96 from Vishay Semiconductors is a 62 V, ±5 % tolerance, 1 W surface-mount Zener diode in MELF (DO-213AB) package, featuring low dynamic impedance (47.1 Ω at 4 mA), low regulation factor, and glass-passivated junction for stable voltage reference in power supply regulation and overvoltage protection circuits.
For engineers reviewing the GLL4759A-E3/96 datasheet, GLL4759A-E3/96 pinout, GLL4759A-E3/96 application, or GLL4759A-E3/96 equivalent, this page delivers verified electrical parameters, thermal performance data, MELF package dimensions, and real-world design context for precision voltage clamping and reference applications.
Technical Context
The GLL4759A-E3/96 operates as a single-element, unidirectional Zener diode with cathode-anode polarity defined by the first band on the MELF body. It maintains regulation under DC reverse bias at IZT = 4 mA, with dynamic impedance measured at 1 kHz and specified up to 150 °C junction temperature.
Its glass-passivated chip junction ensures stable breakdown characteristics across temperature, while UL 94 V-0 molding compound and MSL level 1 rating support reflow-compatible assembly. The device is rated for 260 °C peak soldering temperature per J-STD-020 and exhibits a typical temperature coefficient near +0.05 %/°C for VZ = 62 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V nominal, ±5 % tolerance - defines precise clamping threshold for 62 V rail protection or reference generation |
| Power Dissipation (Ptot) | 1000 mW at TT = 75 °C - supports continuous operation in compact PCB layouts with adequate copper thermal relief |
| Zener Test Current (IZT) | 4 mA - standard bias point for measuring VZ and dynamic impedance; enables low-power reference designs |
| Dynamic Impedance (ZZ) | 47.1 Ω at 1 kHz and IZT = 4 mA - ensures tight regulation under small-signal load variations |
| Reverse Leakage (IR) | 0.25 μA max at VR = 47.1 V - minimizes standby current in high-impedance sensing or battery-backed circuits |
| Junction Temperature (Tj) | 150 °C maximum - allows reliable operation in industrial ambient environments up to 125 °C with proper thermal design |
| Package | MELF DO-213AB - cylindrical surface-mount form factor with 2.67 mm diameter, enabling high-density placement and automated pick-and-place |
Pinout & Package
MELF (DO-213AB) package: cylindrical glass-passivated plastic body, 4.7–5.2 mm length, 2.67 mm diameter, cathode identified by first colored band. No discrete pins - terminals are axial end caps requiring symmetric SMT pad layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward conduction terminal / low-side connection | Connected to ground or lower potential node in shunt regulator configuration |
| Cathode (banded end) | Zener breakdown terminal / high-side connection | Connected to input rail or protected node; conducts reverse current above 62 V |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures long-term stability of Zener voltage and low parameter drift over time and temperature cycling |
| UL 94 V-0 flammability rating | Meets stringent safety requirements for consumer and industrial equipment without additional flame-retardant board treatment |
| Low Zener impedance (47.1 Ω) | Delivers <1 % output variation under ±1 mA load transients in feedback reference paths |
| MSL Level 1 moisture sensitivity | Enables direct use from dry pack without baking - reduces manufacturing overhead and handling risk |
| 260 °C peak reflow compatibility | Supports standard lead-free reflow profiles without degradation of junction integrity or parameter shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C62LT1G | 62 V, ±5 %, SOT-23 package, 350 mW Ptot, ZZ = 100 Ω at 5 mA | Lower power rating and higher impedance limit use to low-current references only | Select when board space is constrained and dissipation remains <300 mW |

FAQ
What is the Zener voltage tolerance for GLL4759A-E3/96?
The "A" suffix in GLL4759A-E3/96 denotes ±5 % Zener voltage tolerance at 25 °C, tighter than the standard ±10 % version. This is confirmed in the "Notes" section of the Vishay datasheet (Doc. #85781, Rev. 1.8), where suffix A explicitly defines the 5 % tolerance grade for the entire GLL4735–GLL4763A family.
Does GLL4759A-E3/96 support lead-free reflow soldering?
Yes, GLL4759A-E3/96 is qualified for lead-free reflow with a peak temperature of 260 °C for up to 10 seconds, as stated in the "Soldering Conditions" table (Page 2, Doc. #85781). Its MELF DO-213AB package and UL 94 V-0 compound ensure reliability under JEDEC J-STD-020-compliant profiles.
What is the maximum surge current rating for GLL4759A-E3/96?
The GLL4759A-E3/96 supports a non-repetitive surge current of 125 mA (IZM) for an 8.3 ms pulse width, per JEDEC method, as listed in the "Electrical Characteristics" table (Page 2, Doc. #85781). This value is derived from its 1 W power rating and 62 V Zener voltage.
How does the MELF package of GLL4759A-E3/96 affect thermal performance?
The MELF (DO-213AB) package gives GLL4759A-E3/96 a junction-to-ambient thermal resistance of 170 °C/W, enabling 1 W dissipation at 75 °C terminal temperature. Its cylindrical geometry provides uniform heat distribution and better thermal coupling to copper pads than flat SMD packages like SOD-123.
Is GLL4759A-E3/96 suitable for high-reliability medical applications?
Yes - GLL4759A-E3/96 meets key medical design requirements: UL 94 V-0 flammability, MSL Level 1 handling, 150 °C max junction temperature, and glass-passivated junction for long-term parameter stability. Its 5 % tolerance and low leakage (<0.25 μA) support precision analog functions in certified Class II devices.
