Product details
Overview
HZM6.2NB2TL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 6.26–6.53 V at 5 mA, dynamic resistance of 50 Ω max, power dissipation of 200 mW, and MPAK surface-mount package. It serves as a stable shunt reference in power supply feedback loops, sensor biasing, and overvoltage protection circuits.
For engineers reviewing the HZM6.2NB2TL-E datasheet, HZM6.2NB2TL-E pinout, HZM6.2NB2TL-E application, or HZM6.2NB2TL-E equivalent, key selection criteria include its B2-grade zener voltage tolerance (±2.3% typical), low temperature coefficient (≈+0.04 mV/°C near 6.2 V), 200 mW power rating, and SC-59A-compatible MPAK (PLSP0003ZC-A) footprint for high-density PCB layouts.
Technical Context
The HZM6.2NB2TL-E operates as a two-terminal shunt regulator, maintaining a stable reverse-biased breakdown voltage across its cathode-anode terminals under controlled test current (IZ = 5 mA). Its epitaxial planar construction ensures tight voltage distribution and repeatable dynamic resistance (rd ≤ 50 Ω).
Designed for ambient temperatures from –55°C to +150°C, it features a junction temperature limit of 150°C and thermal derating per Fig.3 - power dissipation decreases linearly above 25°C ambient. The device exhibits a positive temperature coefficient (~+0.04 mV/°C) in the 6.2 V range, enabling predictable drift compensation in reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.26–6.53 V at IZ = 5 mA - defines precise regulation point for feedback or bias networks |
| Dynamic Resistance (rd) | ≤ 50 Ω at IZ = 5 mA - ensures minimal output impedance and low AC ripple in reference paths |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating applies |
| Reverse Current (IR) | ≤ 2 µA at VR = 3.0 V - guarantees low leakage in standby or high-impedance sensing nodes |
| Junction Temperature (Tj) | 150°C maximum - determines thermal design margin for PCB copper area and airflow requirements |
| Package | MPAK (JEITA PLSP0003ZC-A, SC-59A equivalent) - 3-pin SMT footprint with NC, anode, cathode layout |
Pinout & Package
Package: MPAK (PLSP0003ZC-A), JEITA-compliant SC-59A variant; 3-terminal surface-mount package with 1.0 mm × 1.3 mm body, 0.35–0.5 mm lead width, and 2.2–3.0 mm terminal pitch (e dimension).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal - must remain unconnected; no internal bond or circuit function |
| 2 | Anode | Forward-bias terminal; connects to lower-potential node in shunt configuration (e.g., ground or return path) |
| 3 | Cathode | Reverse-bias terminal; connects to regulated voltage node (e.g., feedback divider or supply rail) |
Key Features
| Feature | Design Value |
|---|---|
| B2-grade voltage tolerance | 6.26–6.53 V (±2.3% typical at 5 mA) - enables tighter regulation without external trimming |
| Low dynamic resistance | ≤ 50 Ω - minimizes load-induced voltage shift in precision references |
| MPAK surface-mount package | SC-59A-compatible 3-pin footprint - supports automated placement and high board density |
| Controlled temperature coefficient | +0.04 mV/°C near 6.2 V - allows predictable drift modeling in temperature-critical references |
| High-reliability epitaxial planar process | Stable parametric distribution and low failure rate - suitable for industrial-grade power management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 (Diodes Inc.) | Same nominal 6.2 V, SOT-23 package, ±5% tolerance (B grade), rd ≈ 60 Ω | Higher voltage tolerance and dynamic resistance; less precise but widely stocked | Select when cost sensitivity outweighs regulation accuracy; requires layout change (SOT-23 vs. MPAK) |
| MMSZ4687 (ON Semiconductor) | 6.2 V, SOD-123 package, ±5% tolerance, rd ≈ 70 Ω, Pd = 500 mW | Higher power rating but looser tolerance and larger package; better for surge clamping | Choose for higher-energy transient suppression where 200 mW is insufficient; not drop-in due to footprint mismatch |
Compared with BZX84-C6V2 and MMSZ4687, the HZM6.2NB2TL-E offers tighter voltage control (±2.3% vs. ±5%), lower dynamic resistance (50 Ω vs. ≥60 Ω), and a compact MPAK footprint optimized for space-constrained industrial PCBs - making it preferable for precision analog references where stability and board area are critical.

FAQ
What is the exact zener voltage range for HZM6.2NB2TL-E at 5 mA?
The HZM6.2NB2TL-E has a guaranteed zener voltage range of 6.26 V to 6.53 V when tested at IZ = 5 mA and Ta = 25°C. This B2-grade specification reflects ±2.3% tolerance around the nominal 6.2 V rating, confirmed in the R07DS0358EJ0600 datasheet Table on Page 2. The HZM6.2NB2TL-E maintains this performance across its qualified operating temperature range.
Is HZM6.2NB2TL-E compatible with reflow soldering processes?
Yes, the HZM6.2NB2TL-E in its MPAK package is rated for standard Pb-free reflow profiles per J-STD-020. Its maximum junction temperature of 150°C and thermal characteristics support peak reflow temperatures up to 260°C for ≤30 seconds. The HZM6.2NB2TL-E's glass epoxy PCB mounting guidelines (Page 5, Fig.2) confirm compatibility with industry-standard SMT assembly lines.
Does HZM6.2NB2TL-E have a specified temperature coefficient?
Yes - the HZM6.2NB2TL-E exhibits a positive temperature coefficient of approximately +0.04 mV/°C near its 6.2 V operating point, as shown in Fig.2 (Page 5) of the datasheet. This value is derived from the family-wide γZ vs. VZ curve and applies directly to the HZM6.2NB2TL-E due to its position within the 6.2–6.53 V band. No additional calibration is required for basic drift estimation.
What does the 'B2' suffix indicate in HZM6.2NB2TL-E?
The 'B2' suffix denotes the zener voltage grade: for HZM6.2NB2TL-E, it specifies a tighter 6.26–6.53 V range at 5 mA, distinct from B1 (6.47–6.73 V) and B3 (6.65–6.93 V) grades. This grading enables selective binning for applications demanding improved regulation accuracy without custom trimming. The HZM6.2NB2TL-E's B2 designation is laser-marked as "622" per Page 4 marking table.
Can HZM6.2NB2TL-E replace a standard 1N4735A in existing designs?
No - while both are 6.2 V Zeners, the HZM6.2NB2TL-E uses a 3-pin MPAK package with Pin 1 as NC, whereas the 1N4735A is a 2-pin DO-41 device. Direct replacement would require PCB layout revision. Additionally, the HZM6.2NB2TL-E has lower Pd (200 mW vs. 1 W) and tighter VZ tolerance. Use HZM6.2NB2TL-E only in new designs targeting miniaturization and precision - not as a drop-in substitute for HZM6.2NB2TL-E's legacy counterparts.
