Product details
Overview
HZ6A3L-JTA-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 5.4–5.7 V at 0.5 mA, dynamic resistance of 150 Ω, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference voltage generators and low-drift sensor biasing.
For engineers reviewing the HZ6A3L-JTA-E datasheet, HZ6A3L-JTA-E pinout, HZ6A3L-JTA-E application, or HZ6A3L-JTA-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 that of standard HZ series), DO-35 package compatibility, and thermal stability across −55°C to +175°C storage range.
Technical Context
This device operates as a two-terminal shunt regulator with DC-tested zener characteristics, designed for stable reference generation under low-current conditions (IZ = 0.5 mA). Its low leakage current (<1 μA at VR = 2.0 V) and tightly controlled dynamic impedance support high-precision feedback loops.
The HZ6A3L-JTA-E belongs to the HZ-L series, distinguished by reduced diode noise and improved zener impedance consistency versus legacy HZ parts. It uses silicon planar construction with navy-blue cathode band marking and orange body color in DO-35 glass package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.4–5.7 V at IZ = 0.5 mA - defines stable regulation point for low-power analog references |
| Dynamic Resistance (rd) | 150 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | −55°C to +175°C - enables use in automotive under-hood and industrial control environments |
| Reverse Current (IR) | ≤1 μA at VR = 2.0 V - minimizes quiescent current draw in battery-powered precision circuits |
| Noise Level | ≈1/3–1/10 of standard HZ series - critical for low-noise op-amp references and ADC voltage references |

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

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 (Nexperia) | Zener voltage 5.6 V ±5%, rd = 40 Ω typical but higher noise; SOT-23 surface-mount package | Requires PCB redesign for SMT assembly; better for high-volume automated production but lacks HZ6A3L-JTA-E's low-noise advantage | Select when board space is constrained and noise is secondary to cost and manufacturability |
| 1N5232B (ON Semiconductor) | Zener voltage 5.6 V ±5%, rd = 17 Ω typical, but noise level unspecified and not characterized for low-noise use | DO-35 compatible but no documented noise reduction; suitable for general-purpose regulation, not precision analog | Select only for non-critical voltage clamping where HZ6A3L-JTA-E's noise and impedance specs are unnecessary |
Compared with BZX84-C5V6 and 1N5232B, the HZ6A3L-JTA-E delivers verified low-noise performance and tighter VZ tolerance essential for metrology-grade references, while retaining DO-35 through-hole compatibility and extended thermal range - making it the preferred choice where signal integrity outweighs footprint or unit cost.

FAQ
What is the exact zener voltage range for HZ6A3L-JTA-E at 0.5 mA test current?
The HZ6A3L-JTA-E has a guaranteed zener voltage range of 5.4 V to 5.7 V when tested at IZ = 0.5 mA, as specified in the Renesas REJ03G0182-0300 datasheet. This ±0.15 V tolerance supports high-accuracy reference design without trimming. The HZ6A3L-JTA-E achieves this specification using silicon planar process control and DC testing methodology.
Is HZ6A3L-JTA-E compatible with standard DO-35 footprint and soldering profiles?
Yes, the HZ6A3L-JTA-E uses the JEITA-standard DO-35 package (GRZZ0002ZB-A) with 2.0 mm diameter and 26.0 mm length, matching IPC-7351B axial lead spacing. Its glass-body construction supports standard wave and hand-soldering profiles up to 300°C for ≤3 seconds. The HZ6A3L-JTA-E cathode band orientation follows industry convention with navy-blue marking on the orange body.
How does the noise performance of HZ6A3L-JTA-E compare to standard zener diodes?
The HZ6A3L-JTA-E exhibits approximately 1/3 to 1/10 the noise level of conventional HZ-series zeners, as confirmed in Renesas characterization data. This reduction stems from optimized planar junction geometry and low-defect silicon processing. For designers specifying the HZ6A3L-JTA-E, this translates directly to lower integrated RMS noise in reference-dependent circuits like high-resolution ADCs.
What is the maximum allowable reverse voltage before breakdown for HZ6A3L-JTA-E?
The HZ6A3L-JTA-E is rated for reverse current IR ≤ 1 μA at VR = 2.0 V, meaning it remains in high-impedance blocking state below its zener knee. Breakdown begins near 5.4 V, with full regulation established above 5.4 V at IZ ≥ 0.5 mA. Operation below 5.4 V does not damage the HZ6A3L-JTA-E but provides no regulated output.
Can HZ6A3L-JTA-E be used in automotive under-hood applications?
Yes - the HZ6A3L-JTA-E supports junction temperatures up to +175°C and storage from −55°C to +175°C, meeting requirements for non-safety-critical under-hood modules such as engine control sensor interfaces. Its DO-35 glass package and low thermal resistance enable reliable operation in sealed enclosures. Always verify system-level thermal derating when deploying the HZ6A3L-JTA-E in automotive environments.
