Product details
Overview
HZS6B3L-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 5.7–6.0 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 power management circuits.
For engineers reviewing the HZS6B3L-JTA-E datasheet, HZS6B3L-JTA-E pinout, HZS6B3L-JTA-E application, or HZS6B3L-JTA-E equivalent, key selection criteria include its tight zener voltage tolerance (±0.3 V), low dynamic impedance for stable reference performance, temperature coefficient behavior near 0 mV/°C, and compatibility with through-hole automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage under varying load and line conditions. Its epitaxial planar construction ensures low leakage (≤5 µA at VR = 2.0 V) and consistent zener impedance (≤40 Ω at IZ = 5 mA), critical for low-noise analog supply rails and feedback networks.
The device exhibits a near-zero temperature coefficient around 6 V (≈0 mV/°C per Fig.2), minimizing drift across ambient temperatures from –55°C to +175°C. Its 400 mW power rating is derated linearly above 25°C per the published thermal curve (Fig.3), supporting reliable operation up to 150°C ambient with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.7–6.0 V at IZ = 5 mA - defines regulated output voltage range for feedback or reference use |
| Dynamic Resistance (rd) | ≤40 Ω at IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Current (IR) | ≤5 µA at VR = 2.0 V - guarantees low standby power loss and high impedance in non-conducting state |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating applies |
| Junction Temperature (Tj) | –55°C to +200°C - enables operation in harsh environments including automotive under-hood and industrial controls |
| Package | DO-35 (glass axial) - standard through-hole package compatible with 5 mm pitch auto-insertion equipment |
Pinout & Package
Package: DO-35 glass axial leaded package with cathode band marking. Leads are tinned and suitable for wave soldering and high-speed automatic insertion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to higher potential side in reverse-biased regulation; polarity must be observed for proper conduction |
| 2 (Non-banded End) | Anode | Connected to lower potential (e.g., ground or return path); forms current sink during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | ≤40 Ω at 5 mA - improves regulation accuracy and transient response in feedback loops |
| Tight zener voltage tolerance | ±0.3 V (5.7–6.0 V) - reduces need for external trimming in precision reference designs |
| Near-zero temperature coefficient | ≈0 mV/°C near 6 V - minimizes voltage drift over industrial temperature range (–40°C to +85°C) |
| High reliability construction | Silicon epitaxial planar process with glass passivation - ensures long-term stability and low parameter shift |

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 |
|---|---|---|---|
| 1N4734A | Zener voltage 5.6 V ±5%, rd = 9 Ω, Pd = 1 W, DO-41 package | Higher power and lower impedance but looser voltage tolerance and larger footprint | Preferred where higher surge energy handling is required and board space allows DO-41 |
| BZX55C6V2 | Zener voltage 6.2 V ±5%, rd = 10 Ω, Pd = 500 mW, DO-35 package | Same package but wider VZ tolerance and higher nominal voltage; not interchangeable without circuit recalibration | Consider only if 6.2 V reference is acceptable and tighter grading is unnecessary |
Compared with 1N4734A and BZX55C6V2, HZS6B3L-JTA-E offers tighter voltage tolerance (±0.3 V vs. ±5%), optimized for precision feedback rather than general-purpose clamping, while maintaining DO-35 compatibility and low-temperature-drift performance critical for industrial reference designs.

FAQ
What is the exact zener voltage range for HZS6B3L-JTA-E?
HZS6B3L-JTA-E has a guaranteed zener voltage range of 5.7 V to 6.0 V at test current IZ = 5 mA, corresponding to Grade B3 in the HZS6 family. This tight ±0.15 V tolerance enables precise voltage setting without external calibration, and the value is verified per ROHM's ADE-208-120A(Z) specification document.
Is HZS6B3L-JTA-E suitable for surface-mount assembly?
No, HZS6B3L-JTA-E uses a DO-35 glass axial package with radial leads intended for through-hole mounting and high-speed automatic insertion at 5 mm pitch. It is not compatible with reflow or wave soldering processes designed for SMD components, and no SMT variant is offered in the HZS6B3L-JTA-E ordering code.
What is the maximum reverse current specification for HZS6B3L-JTA-E?
The maximum reverse current for HZS6B3L-JTA-E is 5 µA at VR = 2.0 V and Ta = 25°C. This low leakage supports high-impedance reference nodes and minimizes quiescent power loss in battery-backed or energy-sensitive circuits using the HZS6B3L-JTA-E.
Does HZS6B3L-JTA-E have a specified temperature coefficient?
Yes - HZS6B3L-JTA-E exhibits a zener voltage temperature coefficient near 0 mV/°C at approximately 6 V, as confirmed by ROHM's Fig.2 in the HZS Series datasheet. This behavior minimizes voltage drift across –40°C to +125°C, making the HZS6B3L-JTA-E especially valuable in unregulated thermal environments.
Can HZS6B3L-JTA-E replace a 6.2 V Zener diode in an existing design?
Not directly - HZS6B3L-JTA-E regulates at 5.7–6.0 V, whereas a typical 6.2 V Zener (e.g., BZX55C6V2) has a nominal 6.2 V ±5%. Substituting HZS6B3L-JTA-E would lower the reference or clamp voltage by ~0.2–0.5 V, potentially affecting loop stability or protection thresholds; circuit analysis and validation are required before replacement of HZS6B3L-JTA-E.
