Product details
Overview
P6SMB62 from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 55.8–68.2V, clamping voltage of 89.0V at 7.0A peak pulse current, and DO-214AA (SMB) package. It protects DC power rails in switching mode power supplies, adapters, and display electronics against ESD and surge events per ISO 7637-2 Pulse 1/2a/2b/3a/3b.
For engineers reviewing the P6SMB62 datasheet, P6SMB62 pinout, P6SMB62 application, or P6SMB62 equivalent, key selection criteria include its 50.2V stand-off voltage, <1μA reverse leakage at VWM, 1.0ps response time, and compliance with J-STD-020 moisture sensitivity level 1 - critical for high-reliability automated assembly and automotive-grade surge immunity.
Technical Context
The P6SMB62 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its minimum breakdown threshold of 55.8V (tested at 1.0mA). Its glass-passivated junction ensures stable clamping performance under repetitive transients, while thermal resistance values (RθJC = 10°C/W, RθJA = 55°C/W) support operation up to 150°C junction temperature.
Designed for 10/1000μs surge waveforms, it delivers 600W non-repetitive peak pulse power with a maximum clamping voltage of 89.0V at 7.0A IPPM. Its low forward voltage (VF = 3.5V @ 50A) and polarity marking (cathode band) confirm unidirectional configuration, distinguishing it from bidirectional variants (e.g., P6SMB62C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 55.8V / 68.2V - defines reliable avalanche initiation window under 1.0mA test current |
| VWM | 50.2V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 89.0V @ 7.0A - clamped voltage during 10/1000μs surge, limiting downstream IC stress |
| PPPSM | 600W - peak pulse power handling for transient suppression without failure |
| IR @ VWM | <1μA - ultra-low leakage preserves efficiency in standby and low-power modes |
| Response Time | <1.0ps - enables protection against fast-rising ESD events (IEC 61000-4-2) |
| TJ max | +150°C - supports operation in thermally constrained PCB layouts and industrial environments |

Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapters |
|---|---|
Use Scenario: Input rectifier output or DC bus line in offline SMPS units subject to lightning-induced surges and switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between bulk capacitor and primary-side controller to clamp transients before they reach gate drivers or feedback circuits. Use Value: Limits voltage spikes to ≤89.0V, preventing MOSFET avalanche failure and maintaining regulation integrity under 600W surge conditions. | Use Scenario: Secondary-side DC output rail in wall-mounted adapters powering consumer electronics. IC Role / Device Role / Timing Role: Standoff-rated protector (50.2V) on +5V/+12V outputs, absorbing ESD from hot-plug events and cable discharge. Use Value: Sub-1μA leakage avoids standby current penalty; SMB footprint enables compact layout adjacent to USB or barrel-jack connectors. |
| Flat Panel TV Power Board | Monitor Backlight Inverter |
Use Scenario: 24V or 48V main logic rail in LED-backlit TV power boards exposed to EMI from backlight drivers and digital video interfaces. IC Role / Device Role / Timing Role: Primary overvoltage clamp on microcontroller supply lines, triggered only during fault-level transients (not normal ripple). Use Value: 1.0ps response ensures protection against nanosecond-scale coupling from nearby inverters, preserving firmware execution stability. | Use Scenario: High-voltage boost stage (≥300V) in CCFL or LED backlight inverters where transformer ringing induces repetitive overshoot. IC Role / Device Role / Timing Role: Clamp diode across resonant tank or MOSFET drain, conducting only during >55.8V excursions to limit stress on switching FETs. Use Value: 89.0V clamping reduces peak drain voltage by >30% versus unprotected operation, extending MOSFET lifetime and reducing thermal derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | 60V nominal VBR, 87.1V VC @ 6.9A, same DO-214AA package | Slightly lower clamping voltage but tighter VBR tolerance (±5% vs ±10% for P6SMB62) | Select SMBJ60A when tighter voltage control is required; verify compatibility with 50.2V VWM margin in design. |
| 1.5SMC62A | Same VBR range (55.8–68.2V), 89.0V VC, but DO-214AB (SMC) package (larger footprint) | Higher thermal mass allows longer surge duration handling; not drop-in due to larger pad layout | Choose 1.5SMC62A only if board space permits and higher steady-state power dissipation (5W vs 3W) is needed. |
Compared with SMBJ60A and 1.5SMC62A, the P6SMB62 offers optimal balance of compact SMB footprint, 600W surge rating, and cost-effective unidirectional protection for mid-voltage DC rails - ideal where board area and automated placement are prioritized over marginal VBR tolerance or thermal headroom.

FAQ
What is the polarity configuration of the P6SMB62?
The P6SMB62 is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its cathode band marking and forward voltage specification (VF = 3.5V @ 50A). It conducts in forward bias during surge events and blocks reverse voltage up to 50.2V in normal operation. This differs from bidirectional variants like P6SMB62C, which protect both polarities.
Does the P6SMB62 meet automotive surge immunity standards?
Yes, the P6SMB62 meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), as explicitly stated in its datasheet. Its 600W peak pulse power rating and 89.0V clamping voltage make it suitable for 12V and 24V automotive subsystems such as infotainment power rails and body control modules.
What is the maximum steady-state power dissipation for the P6SMB62?
The P6SMB62 has a steady-state power dissipation (Ptot) of 3W at TA = 25°C, as specified in its Absolute Maximum Ratings table. This value decreases with rising ambient temperature per the derating curve (Fig.2), reaching zero at 150°C. It is intended for transient suppression, not continuous power dissipation.
How does the P6SMB62 compare to the P6SMB62A variant?
The P6SMB62A features a tighter breakdown voltage range (58.9–65.1V vs. 55.8–68.2V for P6SMB62) and slightly lower clamping voltage (85.0V vs. 89.0V at 7.4A). Both share identical package, power rating, and application scope. The P6SMB62A is preferred where tighter VBR tolerance improves system margin, while the P6SMB62 offers broader voltage coverage for less stringent designs.
Is the P6SMB62 RoHS and halogen-free compliant?
Yes, the P6SMB62 is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in its official datasheet. Its molding compound meets UL 94V-0 flammability rating, and matte tin-plated leads comply with J-STD-002 solderability standards - supporting environmentally regulated markets and high-reliability manufacturing.
