Product details
Overview
HZ6.2BPTK-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 5.7 V (min 5.7 V / max 6.0 V), dynamic resistance of 60 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C. It is used in stabilized power supplies, reference voltage sources, and noise-sensitive instrumentation.
For engineers reviewing the HZ6.2BPTK-E datasheet, HZ6.2BPTK-E pinout, HZ6.2BPTK-E application, or HZ6.2BPTK-E equivalent, key selection criteria include its low-noise performance (≈1/3–1/10 lower than standard HZ series), tight zener voltage tolerance, DO-35 package compatibility, and suitability for low-current (<1 mA) precision biasing and voltage clamping.
Technical Context
The HZ6.2BPTK-E operates as a two-terminal shunt regulator with DC-tested zener characteristics. Its low dynamic resistance (60 Ω) and low leakage current support stable regulation under light-load conditions typical in sensor biasing and op-amp reference circuits.
Designed for low-noise applications, it achieves reduced diode noise via optimized silicon planar process and controlled junction geometry. The device exhibits a zener voltage temperature coefficient of approximately −0.04 %/°C (−2.5 mV/°C) near 5.7 V, enabling predictable drift behavior in ambient-temperature-varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.7 V min / 6.0 V max at IZ = 0.5 mA - defines precise clamping threshold for low-power reference design |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under small load current changes |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | 175°C max - enables reliable use in industrial and automotive under-hood environments |
| Reverse Current (IR) | 1 μA max at VR = 2.0 V - guarantees negligible standby leakage in battery-powered systems |

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | Zener voltage 5.6 V ±5%, rd = 9 Ω @ 45 mA, Pd = 1 W, DO-41 package | Higher power, higher test current, higher noise - suited for higher-current regulation, not low-noise biasing | Select only when >20 mA regulation current and thermal margin are available; not drop-in for HZ6.2BPTK-E's low-IZ use case |
| BZX55C5V6 | Zener voltage 5.6 V ±5%, rd = 40 Ω @ 5 mA, Pd = 500 mW, DO-35 package | Higher test current, higher noise, wider VZ tolerance - lacks documented low-noise optimization | Acceptable for general-purpose clamping where noise < −120 dBu is not required; verify noise spec per batch if used in audio paths |
Compared with 1N4734A and BZX55C5V6, the HZ6.2BPTK-E delivers superior low-noise performance and tighter low-current regulation at 0.5 mA, making it uniquely suitable for precision analog signal chains where noise floor and drift dominate design constraints.

FAQ
What is the exact zener voltage range for HZ6.2BPTK-E?
The HZ6.2BPTK-E has a guaranteed zener voltage range of 5.7 V minimum to 6.0 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This 0.3 V span reflects tight process control for low-current reference applications, and the value is confirmed in Renesas document REJ03G0182-0300 Rev.3.00 on Page 2, under "HZ6B3L" row in the Electrical Characteristics table.
Is HZ6.2BPTK-E suitable for low-noise audio applications?
Yes, the HZ6.2BPTK-E is explicitly designed for low-noise applications, with diode noise approximately 1/3–1/10 lower than the standard HZ series. Its low dynamic resistance (60 Ω) and optimized planar junction reduce broadband noise, making it appropriate for microphone preamp clamping and high-fidelity reference buffering where noise floor below −130 dBu is required. This is stated in the Features section of REJ03G0182-0300.
What package type does HZ6.2BPTK-E use, and how is polarity marked?
HZ6.2BPTK-E uses the DO-35 glass axial package (JEITA code GRZZ0002ZB-A), with an orange-colored body and a navy-blue cathode band. Pin 1 (cathode) is the banded end; Pin 2 (anode) is the opposite end. Package dimensions and marking are specified on Page 5 of REJ03G0182-0300 Rev.3.00, confirming mechanical compatibility with standard DO-35 footprints.
What is the maximum power dissipation and derating behavior of HZ6.2BPTK-E?
HZ6.2BPTK-E has a maximum power dissipation of 400 mW at Ta = 25°C, with linear derating above 25°C as shown in Figure 3 on Page 4 of REJ03G0182-0300. Derating begins immediately beyond 25°C ambient, reaching zero dissipation at approximately 150°C ambient - consistent with its 175°C junction rating and thermal resistance characteristics.
Does HZ6.2BPTK-E have a specified zener voltage temperature coefficient?
Yes, the zener voltage temperature coefficient (γZ) for HZ6.2BPTK-E is approximately −0.04 %/°C (or −2.5 mV/°C), derived from Figure 2 on Page 4 of REJ03G0182-0300, which plots γZ vs. VZ for the HZ-L Series. At ~5.7 V, the curve intersects −0.04 %/°C, indicating predictable negative drift useful for temperature-compensated designs.
