Product details
Overview
ZPY6V2-TR from Vishay Semiconductors is a silicon planar power Zener diode in DO-41 package, rated for 1300 mW total power dissipation at 25 °C ambient, with nominal Zener voltage 6.2 V (±0.4 V tolerance), dynamic resistance 183 Ω at 100 mA test current, and temperature coefficient –1 × 10⁻⁴/°C - used in high-stability voltage regulation and overvoltage clipping circuits for industrial power supplies.
For engineers reviewing the ZPY6V2-TR datasheet, ZPY6V2-TR pinout, ZPY6V2-TR application, or ZPY6V2-TR equivalent, key selection criteria include its 6.2 V nominal Zener voltage, 100 mA test current, 183 Ω dynamic impedance, –1 × 10⁻⁴/°C temperature coefficient, and DO-41 package compatibility with through-hole PCB assembly and thermal derating per Fig. 1 in Vishay Doc. 85790.
Technical Context
The ZPY6V2-TR operates as a single-element, cathode-marked, silicon planar Zener diode optimized for stable DC voltage reference and transient voltage suppression in linear regulator feedback paths and protection clamps. Its design targets low dynamic resistance (183 Ω) and tight voltage tolerance (±0.4 V) at 100 mA, enabling precise regulation under moderate load conditions.
Thermal performance is defined by junction-to-ambient thermal resistance of 110 K/W (with leads held at ambient at 4 mm from case), maximum junction temperature of 175 °C, and MSL Level 1 moisture sensitivity - supporting standard reflow and hand-soldering without bake preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8 V min. / 6.2 V nom. / 6.6 V max. - defines stable regulation point with ±6.5% tolerance at 100 mA test current |
| Test Current (IZT) | 100 mA - operating point where VZ and dynamic resistance are specified; supports robust regulation in medium-power circuits |
| Dynamic Resistance (ZZ) | 183 Ω at 1 kHz - low impedance ensures minimal output voltage variation under changing load current |
| Power Dissipation (Ptot) | 1300 mW at Tamb = 25 °C - enables use in compact power supply rails without forced cooling |
| Temperature Coefficient (TCVZ) | –1 × 10⁻⁴/°C - negative drift compensates for positive thermal effects in adjacent components |
| Junction Temperature (Tj) | 175 °C max. - supports operation in high-temperature industrial environments including motor control enclosures |
| Reverse Leakage (IR) | < 0.5 μA at 2.0 V - ensures negligible standby current in battery-backed or low-power monitoring circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A-T | 6.2 V nominal, 1000 mW Ptot, 100 mA IZT, 10 Ω ZZ, DO-41 - lower power rating and lower dynamic resistance | Less suitable for sustained 1300 mW dissipation; better for low-impedance reference in low-current circuits | Select when lower ZZ and tighter VZ tolerance (±5%) are prioritized over power handling |
| BZX85C6V2 | 6.2 V nominal, 1300 mW Ptot, 34 mA IZT, 10 Ω ZZ, DO-41 - same power rating but lower test current and much lower ZZ | Optimized for low-current regulation; not recommended for 100 mA continuous operation due to thermal stress | Select when operating near 34 mA and requiring ultra-low dynamic impedance in sensor biasing |
Compared with ZPY6V2-TR, the 1N4735A-T offers lower dynamic resistance but reduced thermal margin, while BZX85C6V2 matches power rating but shifts optimal operating point to lower current - making ZPY6V2-TR uniquely suited for 100 mA, 1300 mW, low-drift applications in industrial power stages.

FAQ
What is the nominal Zener voltage and tolerance of ZPY6V2-TR?
The ZPY6V2-TR has a nominal Zener voltage of 6.2 V with a tolerance range of 5.8 V (min) to 6.6 V (max) at 100 mA test current, corresponding to ±6.5% deviation. This specification is verified per Vishay Document 85790 Rev. 2.4 and applies under standard 25 °C ambient conditions. The ZPY6V2-TR maintains this voltage stability across its rated power and temperature range.
What is the maximum power dissipation for ZPY6V2-TR and how does it derate with temperature?
ZPY6V2-TR has a maximum power dissipation of 1300 mW at 25 °C ambient, derating linearly to zero at 150 °C ambient per Fig. 1 in Vishay Doc. 85790. Derating slope is approximately 11.7 mW/°C above 25 °C. This thermal profile allows ZPY6V2-TR to sustain 800 mW at 70 °C ambient - critical for enclosed industrial power modules where airflow is limited.
Does ZPY6V2-TR have a specified temperature coefficient, and what is its impact on circuit design?
Yes, ZPY6V2-TR has a temperature coefficient of –1 × 10⁻⁴/°C at 100 mA, meaning its Zener voltage decreases by 0.0001 V per °C rise. This negative drift helps counteract positive thermal coefficients in associated resistors and op-amps. In ZPY6V2-TR-based references, this enables improved overall temperature stability - especially in feedback loops where complementary drifts cancel.
Is ZPY6V2-TR compatible with automated through-hole assembly processes?
Yes, ZPY6V2-TR uses the standard DO-41 (DO-204AL) axial package with 2.6 mm max body diameter and 0.86 mm max lead diameter, fully compatible with wave soldering and selective soldering equipment. Its MSL Level 1 rating confirms no moisture sensitivity - eliminating bake requirements before assembly. The ZPY6V2-TR's 310 mg weight and lead spacing also meet IPC-A-610 Class 2 mechanical fit standards.
What is the dynamic resistance of ZPY6V2-TR and why does it matter in regulation circuits?
ZPY6V2-TR exhibits 183 Ω dynamic resistance at 1 kHz and 100 mA test current. This value quantifies how much the Zener voltage changes per unit change in current - lower ZZ yields tighter regulation. At ±10 mA load variation, ZPY6V2-TR's output shifts only ±1.83 V, making it suitable for applications demanding <±2% output stability without active feedback, such as analog sensor biasing or reset threshold generation.
