Product details
Overview
ZGL41-160A-E3/97 from Vishay General Semiconductor is a surface-mount, glass-passivated Zener diode in a GL41 (DO-213AB) MELF package, rated for 160 V nominal Zener voltage at 2.3 mA test current, 1.0 W total power dissipation, and 700 Ω maximum dynamic impedance at IZT - used for precision voltage regulation and overvoltage protection in industrial power supplies and DC-DC converter feedback loops.
For engineers reviewing the ZGL41-160A-E3/97 datasheet, ZGL41-160A-E3/97 pinout, ZGL41-160A-E3/97 application, or ZGL41-160A-E3/97 equivalent, key selection criteria include Zener voltage tolerance (±5 %), low regulation factor, 1.0 μA maximum reverse leakage at 121.6 V, 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 indicated by a red band. Its glass-passivated junction ensures stable breakdown characteristics and low long-term drift under continuous DC bias.
The ZGL41-160A-E3/97 delivers regulated reference voltage in open-loop or feedback-controlled circuits where tight voltage tolerance, low Zener impedance (700 Ω at 2.3 mA), and minimal temperature coefficient (≈+0.11 mV/°C/V at 160 V) are required - consistent with its 152–168 V min–max VZ range and 0.25 mA minimum knee current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 152–168 V at 2.3 mA - defines precise clamping threshold for overvoltage protection and reference generation |
| Total Power Dissipation (Ptot) | 1.0 W at TL = 75 °C - sets maximum steady-state thermal load on PCB copper pad area (8 mm × 8 mm) |
| Zener Impedance (ZZT) | 700 Ω max at IZT - determines regulation accuracy under varying load current |
| Reverse Leakage (IR) | 1.0 μA max at VR = 121.6 V - ensures low standby power loss in high-impedance bias networks |
| Junction Temperature (TJ) | -55 to +150 °C - supports operation in harsh industrial environments without derating below -40 °C |
| Surge Current (IRM) | 6.3 A peak (8.3 ms pulse) - withstands transient line surges in AC/DC front-end stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-regulating diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5267B-TAP | 160 V nominal, 500 mW Ptot, DO-35 package, higher ZZT (1000 Ω) | Limited to lower-power regulation; unsuitable for >0.5 W continuous dissipation | Select when board space allows axial leads and thermal budget is constrained |
| BZX85C160-TR | 160 V nominal, 1.3 W Ptot, DO-41 package, 1000 Ω ZZT, higher IR (5 μA) | Better power handling but looser regulation and higher leakage compromises precision references | Prefer for ruggedized industrial designs where layout flexibility permits larger through-hole footprint |
Compared with 1N5267B-TAP and BZX85C160-TR, the ZGL41-160A-E3/97 offers superior regulation accuracy (700 Ω vs ≥1000 Ω ZZT), lower leakage (1.0 μA vs ≥5 μA), and MELF geometry optimized for automated SMT - making it the preferred choice for high-reliability, high-density 160 V reference and clamp functions.

FAQ
What is the Zener voltage tolerance of ZGL41-160A-E3/97?
The ZGL41-160A-E3/97 has a Zener voltage range of 152 V to 168 V at 2.3 mA test current, corresponding to a ±5 % tolerance around the nominal 160 V rating. This tolerance is guaranteed over the full operating temperature range (-55 to +150 °C) and remains stable due to the device's glass-passivated junction and low temperature coefficient.
Does ZGL41-160A-E3/97 support lead-free reflow soldering?
Yes, ZGL41-160A-E3/97 meets J-STD-020C MSL Level 1 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, ensuring reliable wetting and intermetallic formation without whisker risk (M3 suffix variant available for class 1A whisker testing).
What is the maximum continuous forward voltage drop for ZGL41-160A-E3/97?
The ZGL41-160A-E3/97 exhibits a maximum continuous forward voltage of 1.5 V at 0.5 A forward current. While primarily operated in reverse breakdown, this VF rating ensures predictable behavior during fault conditions or bidirectional transient suppression configurations where forward conduction may occur.
How does the ZGL41-160A-E3/97 perform under surge conditions?
ZGL41-160A-E3/97 supports a maximum non-repetitive surge current of 6.3 A for an 8.3 ms pulse width, per JEDEC test method. This enables robust protection against line transients in AC/DC front-ends and motor drive snubbers without degradation, provided the average power remains within the 1.0 W derated limit at the applied lead temperature.
Is ZGL41-160A-E3/97 suitable for use in automotive applications?
ZGL41-160A-E3/97 is rated for commercial-grade operation (-55 to +150 °C) and RoHS compliance but is not AEC-Q200 qualified. For automotive applications requiring qualification, engineers should consult Vishay's AEC-Q200-certified Zener families such as the VZL series - while ZGL41-160A-E3/97 remains appropriate for non-safety-critical industrial or telecom systems with equivalent thermal and environmental demands.
