Product details
Overview
HZS6.2NB3TA-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies. It delivers a nominal zener voltage of 6.2 V (min 6.16 V, max 6.40 V) at 5 mA test current, with dynamic resistance of 3.0 Ω, maximum power dissipation of 400 mW, and operates across –55°C to +175°C storage temperature range. It is used in voltage reference and overvoltage protection circuits in consumer and industrial electronics.
For engineers reviewing the HZS6.2NB3TA-E datasheet, HZS6.2NB3TA-E pinout, HZS6.2NB3TA-E application, or HZS6.2NB3TA-E equivalent, key selection criteria include zener voltage tolerance (±1.6% typical), low dynamic impedance for stable regulation, 400 mW power rating under PCB-mount thermal conditions, and compatibility with 5 mm-pitch high-speed automatic insertion.
Technical Context
This device belongs to the HZS-N Series, fabricated using silicon planar process technology to achieve tight zener voltage distribution and low leakage. Its junction temperature rating of 200°C supports operation in thermally demanding environments, and its specified reverse current ≤5 μA at VR = 4.0 V ensures minimal standby power loss.
The diode exhibits a zener voltage temperature coefficient of approximately +2.0 mV/°C near 6.2 V, enabling predictable drift compensation in reference designs. Its MHD package (JEITA code GRZZ0002ZC-A) features axial leads optimized for through-hole mounting and automated assembly, with cathode band marking for polarity identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 |
|---|---|---|---|
| 1N4735A-T | Zener voltage 6.2 V ±5%, rd = 5.0 Ω, Pd = 1.0 W, DO-41 package | Higher power rating but looser tolerance and higher impedance - suitable where thermal margin >400 mW is available. | Select when board space permits larger DO-41 footprint and tighter regulation is secondary to power handling. |
| BZX55C6V2-TR | Zener voltage 6.2 V ±5%, rd = 10 Ω, Pd = 500 mW, DO-35 package | Lower cost, wider tolerance, higher impedance - appropriate for non-critical biasing or clamping only. | Choose for cost-sensitive consumer applications where ±5% voltage accuracy and 10 Ω impedance are acceptable. |

FAQ
What is the zener voltage tolerance of HZS6.2NB3TA-E?
HZS6.2NB3TA-E has a B3 grade zener voltage specification of 6.16 V minimum to 6.40 V maximum at 5 mA test current, corresponding to a ±1.6% tolerance around the nominal 6.2 V value. This tight tolerance is confirmed in the Renesas HZS-N Series datasheet REJ03G0185-0300 Rev.3.00 and enables precise voltage referencing without external calibration. The HZS6.2NB3TA-E achieves this via silicon planar process control and grade binning during final test.
Does HZS6.2NB3TA-E support high-temperature operation?
Yes, HZS6.2NB3TA-E supports junction temperatures up to 200°C and storage temperatures from –55°C to +175°C. Its silicon planar construction and MHD package enable reliable operation in thermally demanding environments such as industrial motor drives and automotive under-hood modules. The HZS6.2NB3TA-E maintains specified electrical characteristics within these limits when mounted on standard FR-4 PCBs with adequate copper area, as validated in Renesas thermal characterization data.
What is the dynamic resistance of HZS6.2NB3TA-E and why does it matter?
HZS6.2NB3TA-E has a maximum dynamic resistance of 3.0 Ω at 5 mA zener current. This low impedance ensures minimal output voltage variation under changing load conditions - for example, a 6 mA load step induces less than 18 mV shift. In practical terms, this makes the HZS6.2NB3TA-E suitable for precision reference nodes in feedback loops and comparator circuits where stability is critical. The value is measured per JEDEC JESD24 standard and documented in the official Renesas datasheet.
Is HZS6.2NB3TA-E compatible with automated through-hole insertion equipment?
Yes, HZS6.2NB3TA-E uses the MHD package (JEITA code GRZZ0002ZC-A) with standardized 5 mm lead pitch, making it fully compatible with high-speed axial component insertion machines. The package dimensions - 2.0 mm body diameter, 26.0 mm lead length, and black cathode band - conform to IPC-J-STD-020 requirements for automated handling and placement. This compatibility is explicitly stated in the "Ordering Information" section of the Renesas HZS-N Series datasheet.
What is the reverse leakage current specification for HZS6.2NB3TA-E?
HZS6.2NB3TA-E specifies a maximum reverse current (IR) of 5 μA at VR = 4.0 V, measured at 25°C ambient. This low leakage ensures minimal power loss in standby or battery-operated applications, supporting multi-year operation in devices like smoke detectors and remote sensors. The parameter is verified per Renesas test conditions and appears in the Electrical Characteristics table of the official datasheet REJ03G0185-0300.
