Product details
Overview
HZS6C3L-JTA-E from ROHM Semiconductor is a silicon epitaxial planar Zener diode designed for precision voltage regulation in stabilized power supplies, with a nominal zener voltage of 6.1–6.4 V, 400 mW power dissipation, 40 Ω dynamic resistance at 5 mA, and operation up to 200°C junction temperature - deployed in industrial DC-DC feedback loops and reference circuits.
For engineers reviewing the HZS6C3L-JTA-E datasheet, HZS6C3L-JTA-E pinout, HZS6C3L-JTA-E application, or HZS6C3L-JTA-E equivalent, key selection criteria include verified zener voltage tolerance (±0.3 V), low leakage (<5 µA at VR = 2.0 V), thermal stability (−0.05%/°C tempco near 6.2 V), and compatibility with 5 mm-pitch automated insertion equipment.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with DC-tested characteristics, delivering stable reference voltage under fixed current conditions (IZ = 5 mA). Its epitaxial planar construction ensures low noise, tight voltage distribution, and repeatable dynamic impedance performance across production lots.
The device exhibits a negative temperature coefficient near 6.2 V (≈ −0.05%/°C), enabling predictable drift compensation in multi-stage regulators. It is rated for continuous operation at ambient temperatures up to +175°C storage and +200°C junction, with derating applied above 25°C per the published power vs. ambient curve.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 6.1–6.4 V at IZ = 5 mA - defines precise regulation point for feedback networks |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - sets maximum steady-state thermal load without heatsinking |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - determines output impedance and ripple rejection capability |
| Reverse Leakage (IR) | ≤5 µA at VR = 2.0 V - ensures minimal error current in high-impedance bias paths |
| Junction Temperature (Tj) | 200°C max - supports operation in enclosed, high-temperature industrial enclosures |
| Tempco (γZ) | ≈ −0.05%/°C near 6.2 V - enables predictable voltage drift modeling over temperature |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A | Zener voltage 6.2 V ±5%, rd = 7 Ω, Pd = 1 W, DO-41 package | Higher power and lower impedance but larger footprint and looser tolerance | Prefer when higher surge energy handling or tighter rd is required; verify board space and thermal mass |
| BZX55-C6V2 | Zener voltage 6.2 V ±5%, rd = 10 Ω, Pd = 500 mW, DO-35 package | Near-identical package but wider voltage tolerance and lower rd than HZS6C3L-JTA-E | Acceptable where ±5% VZ is sufficient and lower impedance improves loop stability |
Compared with 1N4735A and BZX55-C6V2, HZS6C3L-JTA-E offers tighter voltage tolerance (±0.3 V vs. ±5%), optimized for precision feedback rather than general-purpose clamping - making it preferred in closed-loop DC-DC control where regulation accuracy directly impacts system efficiency and compliance.

FAQ
What is the exact zener voltage range for HZS6C3L-JTA-E?
HZS6C3L-JTA-E has a guaranteed zener voltage range of 6.1 V to 6.4 V when tested at IZ = 5 mA and Ta = 25°C. This ±0.3 V tolerance is tighter than standard Zener diodes and supports precision regulation in feedback networks where output accuracy is critical. The value is confirmed in ROHM's ADE-208-120A(Z) datasheet Rev 1, Table on page 3.
Is HZS6C3L-JTA-E suitable for surface-mount assembly?
No, HZS6C3L-JTA-E uses a DO-35 glass axial package with radial leads and is designed for through-hole mounting. It is explicitly rated for 5 mm-pitch high-speed automatic insertion, not reflow or wave soldering. For SMD alternatives, consider ROHM's UDZS series Schottky Zeners, but note those differ in construction and electrical behavior from HZS6C3L-JTA-E.
What is the maximum reverse leakage current for HZS6C3L-JTA-E?
The maximum reverse leakage current (IR) for HZS6C3L-JTA-E is 5 µA when VR = 2.0 V and Ta = 25°C. This low leakage ensures minimal error current in high-impedance reference paths, such as those feeding op-amp inputs or ADC reference pins. The specification is documented in the Electrical Characteristics table on page 3 of the official datasheet.
Does HZS6C3L-JTA-E have a specified temperature coefficient?
Yes, HZS6C3L-JTA-E exhibits a temperature coefficient of approximately −0.05%/°C near its nominal 6.2 V zener voltage, as shown in Figure 2 of the datasheet. This negative tempco is typical for Zeners in the 5–7 V range and enables predictable drift modeling in temperature-sensitive applications like sensor excitation and precision references.
Can HZS6C3L-JTA-E replace a 6.2 V Zener in existing designs without layout changes?
Yes - HZS6C3L-JTA-E uses the standard DO-35 package with 5 mm lead pitch, matching mechanical footprints of legacy 6.2 V Zeners like 1N4735A and BZX55-C6V2. No PCB modifications are needed, though designers should verify that the tighter 6.1–6.4 V tolerance and 40 Ω rd meet system-level regulation and stability requirements before drop-in substitution.
