Product details
Overview
ZGL41-170A-E3/97 from Vishay General Semiconductor is a surface-mount, glass-passivated Zener diode with nominal Zener voltage 170 V, 1.0 W power rating, and low dynamic impedance (800 Ω at 2.2 mA test current), designed for precision voltage regulation and overvoltage protection in high-voltage DC power supplies and industrial control circuits.
For engineers reviewing the ZGL41-170A-E3/97 datasheet, ZGL41-170A-E3/97 pinout, ZGL41-170A-E3/97 application, or ZGL41-170A-E3/97 equivalent, key selection criteria include Zener voltage tolerance (±5.3% at 170 V), reverse leakage (≤1.0 μA at 136.2 V), surge current capability (5.9 A), thermal stability (TJ max = 150 °C), and DO-213AB (GL41) MELF package compatibility with automated placement.
Technical Context
This device operates as a single-element, cathode-marked (red band), silicon-based voltage-regulating diode with a glass-passivated junction ensuring stable breakdown characteristics and low long-term drift. Its low regulation factor and 800 Ω Zener impedance at IZT = 2.2 mA support tight voltage reference performance under varying load conditions.
The GL41 (DO-213AB) plastic MELF package provides mechanical robustness, UL 94 V-0 flammability rating, and matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102 solderability standards. It meets MSL Level 1 with peak reflow temperature up to 250 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Zener Voltage (VZ) | 162–179 V (nominal 170 V); defines precise clamping threshold for overvoltage protection and reference stability |
| Power Dissipation (Ptot) | 1000 mW at TL = 75 °C; enables sustained operation in compact PCB layouts without forced cooling |
| Zener Impedance (ZZT) | 800 Ω at IZT = 2.2 mA; ensures minimal output voltage variation under dynamic load transients |
| Reverse Leakage (IR) | ≤1.0 μA at VR = 136.2 V (80% of VZ); guarantees low standby power loss in high-impedance bias networks |
| Surge Current (IRM) | 5.9 A (8.3 ms pulse); withstands transient energy from inductive switching or lightning-induced surges |
| Junction Temperature (TJ) | -55 to +150 °C; supports deployment in automotive under-hood, industrial motor drives, and outdoor power electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX85C170 (Nexperia) | DO-41 package (axial lead), higher ZZT = 1200 Ω, wider VZ tolerance (±10%) | Not suitable for automated SMT assembly; requires through-hole mounting and manual rework | Select when board-level repairability or legacy through-hole compatibility is prioritized over impedance and footprint density |
| 1N5368B (ON Semiconductor) | DO-204AL (DO-41) package, Ptot = 5 W, VZ = 170 V ±5%, but larger footprint and higher thermal mass | Used in high-power linear regulators where heat sinking is available; incompatible with MELF tape-and-reel feeders | Select only when >1 W continuous dissipation is required and GL41 footprint constraints do not apply |
Compared with BZX85C170 and 1N5368B, ZGL41-170A-E3/97 delivers superior SMT manufacturability, tighter impedance control, and smaller PCB area-critical for space-constrained industrial and automotive modules where Zener regulation must coexist with dense analog signal conditioning.

FAQ
What is the Zener voltage tolerance for ZGL41-170A-E3/97?
ZGL41-170A-E3/97 has a Zener voltage range of 162 V to 179 V at IZT = 2.2 mA, corresponding to a nominal 170 V with ±5.3% tolerance. This specification is verified per JEDEC test methods and applies under steady-state conditions at TA = 25 °C. The ZGL41-170A-E3/97 datasheet confirms this range in Table 1 of Document Number 88409.
Is ZGL41-170A-E3/97 RoHS-compliant?
Yes, ZGL41-170A-E3/97 is RoHS-compliant, as indicated by the "E3" suffix in its part number. Vishay specifies that base P/N-E3 variants meet commercial-grade RoHS requirements per Directive 2011/65/EU, with lead-free matte tin plating and halogen-free molding compound. Full compliance documentation is available via Vishay's material declaration portal for ZGL41-170A-E3/97.
What is the maximum surge current rating for ZGL41-170A-E3/97?
ZGL41-170A-E3/97 supports a maximum non-repetitive surge current (IRM) of 5.9 A, defined per JEDEC method using an 8.3 ms pulse width square wave. This value is measured at TA = 25 °C and reflects the device's ability to absorb transient energy without parametric shift. The ZGL41-170A-E3/97 datasheet lists this in the Electrical Characteristics table under "MAXIMUM SURGE CURRENT".
Does ZGL41-170A-E3/97 have a specified temperature coefficient?
ZGL41-170A-E3/97 exhibits a positive temperature coefficient typical of high-voltage Zeners, with Fig. 6 in the official datasheet showing ~120 mV/°C at 170 V. While no single-value TC is guaranteed across the full range, the curve confirms monotonic increase in VZ with junction temperature-critical for predicting regulation drift in thermally variable environments where ZGL41-170A-E3/97 is deployed.
What does the "/97" suffix mean in ZGL41-170A-E3/97?
The "/97" suffix in ZGL41-170A-E3/97 indicates the preferred package code for 13-inch diameter plastic tape-and-reel delivery, containing 5000 units per reel. This differs from "/96", which denotes 7-inch reels of 1500 units. Both share identical electrical and mechanical specifications; the ZGL41-170A-E3/97 variant is optimized for high-volume SMT line feeding.
