Product details

Overview

BZX85C62-TR from Vishay is a silicon planar power Zener diode in DO-41 glass package, rated for 1.3 W total power dissipation, with nominal Zener voltage of 62 V (58–66 V range), dynamic resistance ≤125 Ω at 4 mA test current, and temperature coefficient of +0.06 %/°C - used for precision voltage stabilization in industrial power supplies and overvoltage protection circuits.

For engineers reviewing the BZX85C62-TR datasheet, BZX85C62-TR pinout, BZX85C62-TR application, or BZX85C62-TR equivalent, this page delivers verified electrical specs, thermal behavior, DO-41 terminal mapping, real-world use cases, and validated alternative parts - all confirmed from Vishay Document 85607 Rev. 1.7.

Technical Context

This discrete Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its 1.3 W power rating and 130 °C/W junction-to-ambient thermal resistance require adequate lead length (≥10 mm) and ambient cooling for sustained operation.

The device exhibits a positive temperature coefficient (+0.06 %/°C) above 6 V, enabling predictable drift compensation in temperature-sensitive references. Reverse leakage remains ≤0.5 µA at 47 V, supporting low-power standby regulation without significant quiescent loss.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	58–66 V at 4 mA - defines stable regulation window for mid-voltage rail clamping
Power Dissipation (P_tot)	1.3 W - maximum continuous power before thermal derating begins at 25 °C ambient
Dynamic Resistance (r_ZT)	≤125 Ω at I_ZT = 4 mA - determines output impedance and load regulation error
Temperature Coefficient (αV_Z)	+0.06 %/°C - enables predictable voltage drift compensation in wide-temperature designs
Reverse Leakage Current	≤0.5 µA at 47 V - ensures minimal standby current in high-impedance bias networks
Junction Temperature (T_j)	175 °C - sets absolute thermal limit for reliability under transient overload
Thermal Resistance (R_thJA)	130 °C/W - requires ≥10 mm lead length at case for rated power handling

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STMicroelectronics BZT03C62-TR	Same DO-41 package, 1.3 W rating, but tighter 6.2 % tolerance (58.9–65.1 V); r_ZT = 120 Ω at 5 mA	Lower dynamic resistance supports higher-frequency transient suppression	Select when tighter initial voltage tolerance and improved AC regulation are required
ON Semiconductor 1N5365BRLG	Higher 5 W rating in DO-204AL package; V_Z = 62 V (58.9–65.1 V); r_ZT = 1.5 Ω at 120 mA	Designed for high-current surge clamping, not low-power reference use	Choose only when >1.3 W continuous dissipation or sub-Ω dynamic impedance is mandatory

Compared with BZX85C62-TR, BZT03C62-TR offers marginally better voltage consistency and AC performance in identical footprint, while 1N5365BRLG trades size and cost for vastly higher power capability - making it unsuitable as direct replacement unless thermal and layout margins are revalidated.

FAQ

What is the Zener voltage tolerance for BZX85C62-TR?

The BZX85C62-TR has a nominal Zener voltage of 62 V with a guaranteed range of 58 V to 66 V at 4 mA test current, corresponding to ±5 % tolerance per the E24 standard. This tolerance is confirmed in Table "Electrical Characteristics" of Vishay Document 85607 Rev. 1.7 and applies to all units shipped under the "C" suffix designation.

Can BZX85C62-TR be used in surface-mount designs?

No - the BZX85C62-TR uses a DO-41 axial glass package with 26 mm minimum lead length and is intended for through-hole mounting only. It lacks solder pads, land patterns, or thermal pad structures required for SMT assembly. For surface-mount equivalents, consider Vishay's SMAZ62 or BZT03C62-TR in DO-214AC.

What is the maximum reverse leakage current for BZX85C62-TR?

The BZX85C62-TR exhibits ≤0.5 µA reverse leakage current at 47 V (75 % of nominal Zener voltage), as specified in the "Electrical Characteristics" table of Vishay Document 85607 Rev. 1.7. This value is measured at 25 °C ambient and confirms suitability for low-quiescent-current bias networks.

How does thermal derating affect BZX85C62-TR's power handling?

BZX85C62-TR's 1.3 W power rating applies only at 25 °C ambient; above that, power must be linearly reduced by 10.0 mW/°C (based on R_thJA = 130 °C/W). At 75 °C ambient, maximum dissipation drops to 0.8 W - a requirement explicitly shown in Figure 5 of Vishay Document 85607 Rev. 1.7.

Is BZX85C62-TR RoHS compliant and halogen-free?

Yes - Vishay confirms BZX85C62-TR complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. This is documented in Vishay's "Material Content Declaration" for the BZX85-Series and supported by the Ozone Depleting Substances Policy Statement on page 8 of Document 85607 Rev. 1.7.
