Product details
Overview
HZS6C2L-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, maximum power dissipation of 400 mW, dynamic resistance ≤40 Ω at 5 mA, and reverse current ≤5 µA at 2.0 V. It supports high-speed automatic insertion on 5 mm-pitch PCBs in industrial and consumer power management circuits.
For engineers reviewing the HZS6C2L-JTA-E datasheet, HZS6C2L-JTA-E pinout, HZS6C2L-JTA-E application, or HZS6C2L-JTA-E equivalent, key selection criteria include verified zener voltage tolerance (±0.3 V), low dynamic impedance for stable regulation under load transients, thermal stability up to 200°C junction temperature, and compatibility with standard through-hole assembly processes.
Technical Context
This discrete Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals. Its epitaxial planar construction ensures low leakage (≤5 µA) and consistent zener impedance (≤40 Ω) under specified test conditions (IZ = 5 mA, DC).
The device is rated for continuous power dissipation of 400 mW at 25°C ambient, with derating above 25°C per the published power vs. ambient temperature curve. Junction temperature is limited to 200°C, and storage temperature range spans −55°C to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.1 V min to 6.4 V max at IZ = 5 mA - defines regulated output voltage window under nominal bias |
| Dynamic Resistance (rd) | ≤40 Ω at IZ = 5 mA - determines regulation stiffness against load current variation |
| Reverse Current (IR) | ≤5 µA at VR = 2.0 V - ensures minimal standby power loss in shunt regulator topologies |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating |
| Junction Temperature (Tj) | 200°C - enables operation in high-temperature industrial environments without thermal shutdown |
| Package | DO-35 glass axial - standardized through-hole footprint compatible with automated insertion equipment |
Pinout & Package
DO-35 glass axial package with two terminals: cathode (marked by band) and anode. Standard lead spacing supports 5 mm-pitch automatic insertion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Breakdown voltage reference terminal | Connected to regulated output node in shunt configuration; polarity must be observed to enable Zener conduction |
| Anode | Return/reference ground path | Typically tied to system ground or common return; completes current path during reverse-bias regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low zener impedance | ≤40 Ω ensures tight voltage regulation under dynamic load steps in feedback-free shunt designs |
| Wide zener voltage spectrum | 6.1–6.4 V range provides precise, grade-specific stabilization for 6 V rail applications |
| High reliability construction | Silicon epitaxial planar process delivers consistent parametric distribution and long-term stability |
| Automated assembly compatibility | 5 mm pitch and DO-35 outline support high-throughput placement in industrial manufacturing lines |

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 | Zener voltage 6.2 V ±5%, Pd = 1 W, DO-41 package, rd ≈ 5 Ω | Higher power rating but larger footprint; less suitable for space-constrained 5 mm-pitch layouts | Select when higher power margin or lower dynamic impedance is required, accepting larger board area |
| BZX55C6V2 | Zener voltage 6.2 V ±5%, Pd = 500 mW, DO-35 package, rd ≈ 10 Ω | Narrower voltage tolerance (±5% vs. ±0.3 V), tighter rd but wider VZ spread | Prefer for cost-sensitive designs where ±5% regulation is acceptable and lower impedance is critical |
Compared with HZS6C2L-JTA-E, the 1N4735A offers higher power headroom but requires layout revision due to DO-41 size, while BZX55C6V2 matches the DO-35 form factor but trades tighter dynamic impedance for looser voltage tolerance-making HZS6C2L-JTA-E optimal for precision 6 V shunt regulation in automated assembly.

FAQ
What is the exact zener voltage range for HZS6C2L-JTA-E?
HZS6C2L-JTA-E has a guaranteed zener voltage range of 6.1 V minimum to 6.4 V maximum when tested at IZ = 5 mA and Ta = 25°C. This ±0.3 V tolerance reflects Grade C3 specification within the HZS6 family and is confirmed in the official ROHM datasheet ADE-208-120A(Z) Rev 1.
Is HZS6C2L-JTA-E suitable for surface-mount assembly?
No, HZS6C2L-JTA-E uses a DO-35 glass axial package with radial leads intended for through-hole mounting. It is optimized for 5 mm-pitch high-speed automatic insertion-not reflow or wave soldering. For SMT alternatives, consider ROHM's UDZS series Schottky Zeners.
What is the maximum reverse current specification for HZS6C2L-JTA-E?
The maximum reverse current for HZS6C2L-JTA-E is 5 µA, measured at VR = 2.0 V and Ta = 25°C. This low leakage supports energy-efficient shunt regulation in battery-backed and low-power systems where standby current must be minimized.
Does HZS6C2L-JTA-E have a specified temperature coefficient?
Yes, the temperature coefficient for HZS6C2L-JTA-E falls within the typical range shown for HZS6B2 in Figure 2 of the datasheet: approximately +3.5 mV/°C (or +0.05%/°C) near 6.2 V. This positive TC is characteristic of Zener diodes in the 5–7 V range and must be accounted for in wide-temperature designs.
Can HZS6C2L-JTA-E replace a 6.2 V Zener diode in an existing design?
Yes, HZS6C2L-JTA-E is a direct functional replacement for 6.2 V Zeners such as 1N4735A or BZX55C6V2 in shunt regulation roles, provided the DO-35 footprint and 400 mW power limit are compatible. Its tighter 6.1–6.4 V tolerance improves accuracy over ±5% parts, but thermal design must verify safe operation at full rated power.
