Product details
Overview
HZM6.2ZMWATR-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 3.0 Ω, and power dissipation rating of 200 mW in the MPAK (SC-59A) surface-mount package. It operates across –55°C to +150°C and supports stable regulation in sensor biasing, ADC reference supplies, and overvoltage protection.
For engineers reviewing the HZM6.2ZMWATR-E datasheet, HZM6.2ZMWATR-E pinout, HZM6.2ZMWATR-E application, or HZM6.2ZMWATR-E equivalent, key selection criteria include zener voltage tolerance (±2.2% at grade B3), low dynamic impedance for ripple suppression, thermal coefficient behavior near zero crossing (~0.02 mV/°C), and compatibility with high-density automated assembly due to its 1.0 mm × 1.3 mm MPAK footprint.
Technical Context
The HZM6.2ZMWATR-E employs a silicon epitaxial planar junction structure optimized for tight zener voltage control and low noise in DC stabilization applications. Its graded doping profile enables predictable breakdown at 6.26–6.53 V with minimal temperature drift near the 6.2 V inflection point observed in the HZM-N series' γZ vs. VZ curve.
Rated for 200 mW power dissipation at 25°C ambient and derated linearly above 25°C (per Fig.3), it sustains reverse current up to 2 µA at VR = 3.0 V and exhibits 3.0 Ω dynamic resistance at IZ = 5 mA - critical for maintaining regulation accuracy under varying load conditions in compact power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.26–6.53 V at IZ = 5 mA - defines precise regulation threshold for reference and clamp circuits. |
| Dynamic Resistance (rd) | 3.0 Ω at IZ = 5 mA - ensures minimal output voltage variation under load transients. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous steady-state power handling in PCB-constrained layouts. |
| Reverse Current (IR) | ≤2 µA at VR = 3.0 V - guarantees low leakage in high-impedance bias networks. |
| Junction Temperature (Tj) | 150°C maximum - enables operation in thermally demanding industrial environments without derating. |
| Package | MPAK (SC-59A), JEITA code PLSP0003ZC-A - 1.0 mm × 1.3 mm footprint supports high-density SMT placement. |
| Temperature Coefficient (γZ) | ≈+0.02 mV/°C near 6.2 V - indicates near-zero TC operating point for stable reference performance. |
Pinout & Package
MPAK (SC-59A) package: 3-terminal surface-mount device with 1.0 mm × 1.3 mm body, 0.35–0.5 mm lead width, and 2.7–3.1 mm overall length. Optimized for reflow soldering and high-speed pick-and-place.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected terminal - must remain floating; no routing or grounding required. |
| 2 | Anode | Forward-biased terminal during conduction; connected to lower-potential node in zener configuration. |
| 3 | Cathode | Connected to regulated output node; reverse-biased during zener operation to maintain fixed VZ. |
Key Features
| Feature | Design Value |
|---|---|
| Grade B3 zener voltage tolerance | ±2.2% (6.26–6.53 V) - enables tighter regulation than standard-grade Zeners in precision references. |

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 (Nexperia) | 6.2 V nominal, ±5% tolerance, 85 Ω rd, SOT-23 package (1.3 × 2.2 mm) | Higher dynamic resistance and looser tolerance reduce regulation accuracy in precision references. | Acceptable for non-critical clamping where cost and availability outweigh performance needs. |
| MMSZ5234B (ON Semiconductor) | 6.2 V nominal, ±5% tolerance, 10 Ω rd, SOD-123 package (1.8 × 1.4 mm) | Larger footprint and higher leakage (≤5 µA) limit use in space-constrained, ultra-low-power designs. | Suitable for general-purpose regulation where MPAK's 1.0 mm width is not required. |
Compared with BZX84-C6V2 and MMSZ5234B, the HZM6.2ZMWATR-E delivers superior voltage stability (±2.2% vs. ±5%), lower dynamic impedance (3.0 Ω vs. ≥10 Ω), and a smaller 1.0 mm × 1.3 mm footprint - making it optimal for high-accuracy, space-limited industrial sensing and reference applications.

FAQ
What is the exact zener voltage range for HZM6.2ZMWATR-E at 5 mA test current?
The HZM6.2ZMWATR-E has a guaranteed zener voltage range of 6.26 V to 6.53 V when tested at IZ = 5 mA, corresponding to Grade B3 specification per Renesas R07DS0358EJ0600 datasheet. This ±2.2% tolerance enables tighter regulation than standard-grade Zeners and is confirmed in the Electrical Characteristics table on page 2.
Does HZM6.2ZMWATR-E have a connected third pin, and what is its function?
Yes - Pin 1 is marked "NC" (No Connect) and is internally unconnected; Pin 2 is the anode; Pin 3 is the cathode. The NC pin must remain unconnected in layout and schematic to avoid unintended parasitic coupling. This 3-pin MPAK configuration maintains mechanical symmetry while isolating unused terminals, as shown in the Pin Arrangement diagram on page 1.
What is the maximum allowable reverse voltage before significant leakage in HZM6.2ZMWATR-E?
The HZM6.2ZMWATR-E specifies ≤2 µA reverse current at VR = 3.0 V, meaning it remains effectively non-conductive below this threshold. Leakage rises sharply only near the zener knee (~6.2 V), so 3.0 V represents a safe upper bound for blocking-mode operation in voltage monitoring or level-shifting circuits.
How does the temperature coefficient of HZM6.2ZMWATR-E compare to other 6.2 V Zeners?
Per Figure 2 in the datasheet, the HZM6.2ZMWATR-E exhibits a temperature coefficient (γZ) of approximately +0.02 mV/°C near 6.2 V - placing it close to the zero-TC inflection point common to 6.2 V Zeners. This results in <±1 mV drift over –25°C to +85°C, outperforming many alternatives with coefficients exceeding ±2 mV/°C.
Is HZM6.2ZMWATR-E suitable for use in automotive applications?
The HZM6.2ZMWATR-E is rated for junction temperatures up to 150°C and storage from –55°C to +150°C, meeting extended temperature requirements. However, Renesas classifies the HZM-N Series as "Standard" grade per their quality policy (Page 6, Note 7), indicating suitability for industrial and consumer equipment - not automotive safety-critical systems unless validated per AEC-Q101 by the end user.
