Product details
Overview
HZ6B2L-JTA from Renesas is a silicon planar Zener diode engineered for low-noise voltage regulation in precision analog circuits, with a nominal zener voltage of 5.6–5.9 V, 400 mW power dissipation, 80 Ω dynamic impedance at 0.5 mA, and DO-35 glass package. It serves in stabilized reference supplies for instrumentation amplifiers and sensor signal conditioning where noise suppression is critical.
For engineers reviewing the HZ6B2L-JTA datasheet, HZ6B2L-JTA pinout, HZ6B2L-JTA application, or HZ6B2L-JTA equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 of standard HZ series), temperature coefficient (−0.02 %/°C typical), and DO-35 mechanical compatibility in space-constrained PCB layouts.
Technical Context
The HZ6B2L-JTA operates as a two-terminal shunt regulator with DC-tested zener characteristics, optimized for low-noise biasing in analog front-ends. Its junction temperature rating of 175°C and storage range of −55 to +175°C support industrial-grade thermal resilience.
Zener voltage is specified at 0.5 mA test current with 1 μA maximum reverse leakage at VR = 2.0 V, and dynamic resistance is measured under DC conditions-ensuring predictable regulation behavior in low-current, high-stability applications such as voltage references for ADCs and DACs.
Key Specifications

| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous operation in compact through-hole designs without forced cooling |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - reduces error current in high-impedance reference nodes |
| Temperature Coefficient (γZ) | −0.02 %/°C typical - enables stable reference over industrial temperature range with minimal drift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference 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 rating but higher noise and looser tolerance; suited for general-purpose regulation, not low-noise analog | Select HZ6B2L-JTA when noise < 1 μV/√Hz and tight voltage tolerance are required; choose 1N4734A only if higher power and relaxed noise specs suffice |
| BZX55C5V6 | Zener voltage 5.6 V ±5%, rd = 40 Ω @ 5 mA, Pd = 500 mW, DO-35 package | Same package but higher dynamic impedance and uncharacterized noise performance; lacks low-noise validation | Use BZX55C5V6 only in cost-sensitive, non-critical references; HZ6B2L-JTA remains preferred for metrology-grade signal chains |
Compared with 1N4734A and BZX55C5V6, the HZ6B2L-JTA delivers superior noise suppression and tighter voltage tolerance in the same DO-35 footprint-making it uniquely suitable for high-fidelity analog reference design where spectral purity and drift control are non-negotiable.

FAQ
What is the exact zener voltage range specified for HZ6B2L-JTA?
The HZ6B2L-JTA has a guaranteed zener voltage range of 5.6 V to 5.9 V when tested at IZ = 0.5 mA and Ta = 25°C. This ±0.3 V tolerance is tighter than standard Zener diodes and supports high-accuracy reference design without post-manufacturing trimming. The HZ6B2L-JTA achieves this specification using silicon planar process technology with controlled doping profiles.
Is HZ6B2L-JTA compatible with DO-35 socket footprints used for other axial Zener diodes?
Yes, the HZ6B2L-JTA uses the standard DO-35 package (JEITA code GRZZ0002ZB-A) with 2.0 mm body diameter and 26.0 mm overall length, matching mechanical dimensions of industry-standard DO-35 Zeners. Its orange body and navy blue cathode band provide visual identification, and the pinout-cathode at terminal 1, anode at terminal 2-is consistent with JEDEC-compliant DO-35 orientation. The HZ6B2L-JTA can be substituted mechanically in existing DO-35 layouts.
How does the noise performance of HZ6B2L-JTA compare to conventional Zener diodes?
The HZ6B2L-JTA exhibits approximately 1/3 to 1/10 the noise level of standard HZ-series Zeners due to optimized silicon planar structure and low-leakage junction design. This reduction is validated in Renesas' characterization data and directly translates to lower voltage ripple in sensitive analog circuits. For example, in a 1 kHz bandwidth, the HZ6B2L-JTA contributes significantly less broadband noise than generic 5.6 V Zeners-making the HZ6B2L-JTA ideal for high-resolution data converters.
What is the maximum reverse leakage current for HZ6B2L-JTA, and under what condition is it specified?
The maximum reverse leakage current for HZ6B2L-JTA is 1 μA, specified at VR = 2.0 V and Ta = 25°C. This low leakage ensures minimal error current in high-impedance reference nodes, preserving accuracy in precision bias networks. The HZ6B2L-JTA maintains this specification across its full operating temperature range, supporting stable performance in industrial environments where leakage-induced drift must be minimized.
Can HZ6B2L-JTA be used in surface-mount designs?
No, the HZ6B2L-JTA is exclusively available in the through-hole DO-35 axial glass package and is not offered in surface-mount variants such as SOD-123 or SOD-323. Its mechanical construction-26.0 mm length, axial leads, and glass encapsulation-requires hole-mounting on PCBs. For SMT-compatible alternatives, designers should evaluate Renesas' HZ-L Series equivalents in SC-40 packages or consult updated product roadmaps; the HZ6B2L-JTA itself is not suitable for reflow or wave soldering processes.
