Product details
Overview
HZS6C1J-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 operates reliably across -55°C to +175°C storage range and supports high-speed automatic insertion on 5 mm-pitch PCBs.
For engineers reviewing the HZS6C1J-E datasheet, HZS6C1J-E pinout, HZS6C1J-E application, or HZS6C1J-E equivalent, key selection criteria include its tight zener voltage tolerance (±0.3 V), low dynamic impedance for stable regulation under load transients, DC-tested electrical characteristics, and compatibility with standard through-hole assembly processes.
Technical Context
This device uses a silicon epitaxial planar structure to achieve low leakage and consistent breakdown behavior. Its zener voltage is specified at 5 mA test current with DC excitation, and temperature coefficient is optimized for mid-range voltages (~6 V) where γZ ≈ +2.0 mV/°C per manufacturer characterization curves.
The HZS6C1J-E exhibits graded zener performance: dynamic resistance drops to ≤40 Ω at IZ = 5 mA, reverse current remains ≤5 µA up to VR = 2.0 V, and junction temperature rating extends to 200°C - enabling use in thermally constrained industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.1–6.4 V at IZ = 5 mA - defines regulated output voltage window for feedback or reference circuits |
| Dynamic Resistance (rd) | ≤40 Ω at IZ = 5 mA - ensures minimal output voltage shift under varying load current |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - sets thermal derating limit for PCB layout and heatsinking |
| Reverse Current (IR) | ≤5 µA at VR = 2.0 V - guarantees low standby power loss in voltage-sense paths |
| Junction Temperature (Tj) | 200°C maximum - supports operation in high-ambient industrial environments |
| Storage Temp Range | -55°C to +175°C - enables use in automotive under-hood or industrial control enclosures |
Pinout & Package
Package: DO-35 glass axial lead package (2.5 mm diameter × 4.5 mm length), lead pitch 5 mm, compatible with high-speed automatic insertion equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to higher potential node; reverse-biased terminal during regulation |
| 2 (Non-banded End) | Anode | Connected to lower potential node (e.g., ground or return path) |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | ≤40 Ω at 5 mA - maintains regulation accuracy despite load current changes |
| Tight zener voltage tolerance | ±0.3 V band (6.1–6.4 V) - reduces need for post-regulation trimming in power supply designs |
| High power dissipation density | 400 mW in DO-35 package - allows compact implementation without external heat sinking |
| DC-tested electrical specs | All parameters verified under DC conditions - eliminates AC-related uncertainty in static bias applications |

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%), rd ≈ 5 Ω, Pd = 1 W, DO-41 package | Higher power handling but larger footprint; less precise voltage tolerance | Preferred when higher surge energy absorption is required and board space permits DO-41 |
| BZX55C6V2 | Zener voltage 6.2 V (±5%), rd ≈ 10 Ω, Pd = 500 mW, DO-35 package | Looser voltage grade (±5% vs. ±0.3 V), slightly higher rd | Selected for cost-sensitive designs where tighter regulation is not critical |
Compared with 1N4735A and BZX55C6V2, the HZS6C1J-E offers superior voltage precision and lower dynamic impedance in the same DO-35 form factor, making it optimal for applications demanding stable reference performance without layout change.

FAQ
What is the exact zener voltage range for HZS6C1J-E?
The HZS6C1J-E has a guaranteed zener voltage range of 6.1 V to 6.4 V when tested at 5 mA DC current, corresponding to Grade C3 in the HZS6 family. This narrow ±0.15 V tolerance enables precise voltage referencing without external trimming. The specification is validated per ROHM's ADE-208-120A(Z) Rev 1 datasheet and applies strictly under DC test conditions.
Is HZS6C1J-E suitable for surface-mount assembly?
No, HZS6C1J-E uses a DO-35 glass axial lead package designed for through-hole mounting and high-speed automatic insertion on 5 mm-pitch PCBs. It is not compatible with reflow or wave soldering processes intended for SMD components. For SMT alternatives, consider ROHM's UDZS series Schottky/Zener devices in SOD-323 packages.
What is the maximum reverse current specification for HZS6C1J-E?
The maximum reverse current (IR) for HZS6C1J-E is 5 µA, measured at VR = 2.0 V and Ta = 25°C. This low leakage ensures minimal parasitic loading in high-impedance reference or sensing nodes. The value is confirmed in the Electrical Characteristics table of the official datasheet and reflects DC testing methodology.
Does HZS6C1J-E have a specified temperature coefficient?
Yes - per ROHM's Fig.2 in the HZS Series datasheet, the temperature coefficient (γZ) for ~6 V-grade devices like HZS6C1J-E is approximately +2.0 mV/°C. This positive coefficient is typical for zeners in the 5–7 V range and must be accounted for in wide-temperature applications where regulation drift affects system accuracy.
Can HZS6C1J-E replace a 6.2 V Zener in existing designs without layout changes?
Yes - HZS6C1J-E shares the DO-35 package and 5 mm lead pitch with industry-standard 6.2 V Zeners, enabling drop-in replacement in through-hole layouts. However, verify that the tighter 6.1–6.4 V range and lower dynamic resistance meet your regulation stability requirements before substitution.
