Product details
Overview
P6SMB62CH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 55.8–68.2 V, clamping voltage of 89.0 V at 7.0 A peak pulse current, and DO-214AA (SMB) package. It provides robust ESD and surge protection for automotive power rails and industrial control inputs.
For engineers reviewing the P6SMB62CH datasheet, P6SMB62CH pinout, P6SMB62CH application, or P6SMB62CH equivalent, key selection criteria include unidirectional polarity, 50.2 V standoff voltage, <1 µA leakage at VWM, AEC-Q101 qualification, and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance.
Technical Context
The P6SMB62CH uses a glass-passivated silicon junction to achieve fast response (<1.0 ps from 0 V to VBR min) and stable clamping under repetitive transients. Its thermal design supports 150°C max junction temperature with RθJA = 55°C/W and RθJC = 10°C/W.
It operates as a unidirectional shunt protector: reverse-biased during normal operation (leakage <1 µA at 50.2 V), then avalanches into low-impedance conduction when transient voltage exceeds VBR (min 55.8 V). The 600 W peak pulse power rating applies to 10/1000 µs waveform per IEC 61000-4-5 and ISO 7637-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 55.8 V / 68.2 V - Ensures reliable triggering above system operating voltage while avoiding false trips |
| VWM | 50.2 V - Maximum continuous reverse working voltage compatible with 48 V automotive and industrial DC systems |
| VC @ IPPM | 89.0 V at 7.0 A - Clamped voltage limits downstream IC stress during ISO 7637-2 Pulse 1 (inductive load dump) |
| PPPSM | 600 W - Sustains high-energy transients without failure under standardized 10/1000 µs surge conditions |
| IR @ VWM | <1 µA - Negligible standby power loss and signal integrity impact in always-on monitoring circuits |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments and enclosed industrial enclosures |
| Package | DO-214AA (SMB) - Surface-mount footprint compatible with automated assembly and IPC-7351B standard land patterns |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode band marking polarity, 0.090 g weight, UL 94V-0 rated compound, and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side return path; enables unidirectional clamping from cathode to anode during overvoltage events |
| Cathode | Reverse-biased input terminal | Connected to protected line (e.g., 48 V rail); avalanche conduction initiates here when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| Glass passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives |
| ISO 7637-2 compliance | Withstands Pulse 1 (inductive switch-off), Pulse 2a/2b (load dump), and Pulse 3a/3b (capacitive coupling) waveforms |
| Low profile SMB package | Enables high-density PCB layouts and compatibility with reflow soldering profiles per J-STD-020 Level 1 |
| Fast response time | <1.0 ps rise-to-breakdown ensures protection before sensitive logic or analog circuitry sustains damage |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 48 V battery-fed ECUs against load dump and alternator transients in passenger vehicles and commercial trucks. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges before they reach DC-DC converters and microcontrollers. Use Value: Limits peak voltage to 89.0 V during 600 W transients, preventing latch-up or gate oxide rupture in downstream 65 V-rated power management ICs. |
Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) connected to PLC I/O modules exposed to field wiring noise. IC Role / Device Role / Timing Role: Shunt protector on signal line to divert EFT bursts and contact bounce spikes away from precision ADC front-ends. Use Value: Sub-µA leakage at 50.2 V avoids loading high-impedance sensor bridges; 89.0 V clamping preserves 24-bit ADC reference integrity. |
| LED Driver Input Protection | Motor Control Gate Drive Protection |
Use Scenario: Securing constant-current LED driver inputs in streetlight and signage applications subject to lightning-induced surges on AC mains lines. IC Role / Device Role / Timing Role: Primary-level TVS on rectified DC bus to absorb energy before it reaches bulk capacitors and controller ICs. Use Value: 600 W rating handles multi-cycle surges from nearby strikes; DO-214AA package allows direct placement at board edge entry points. |
Use Scenario: Shielding high-side and low-side gate drivers in BLDC motor inverters from shoot-through-induced voltage spikes and inductive kickback. IC Role / Device Role / Timing Role: Localized clamping device across gate-source terminals or supply rails of half-bridge drivers. Use Value: 55.8–68.2 V VBR aligns with 60 V-rated MOSFET gate oxide limits; fast <1 ps response prevents millisecond-scale overvoltage exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A | 600 W rating, 60 V VBR min (54.0 V), 93.6 V VC @ 6.4 A; SMA package (smaller footprint, higher RθJA) | Lower clamping voltage margin vs. P6SMB62CH's 89.0 V; less thermal mass for sustained surge duty | Select when space-constrained layouts prioritize smaller footprint over thermal robustness |
| 1.5SMC62A | 600 W rating, 62 V nominal VBR, 100 V VC @ 6.0 A; larger DO-214AB (SMC) package with lower RθJA (40°C/W) | Higher clamping voltage reduces protection margin for 65 V-rated ICs; better heat dissipation for repeated surges | Select when thermal performance under burst-mode operation outweighs board area constraints |
Compared with SMAJ60A and 1.5SMC62A, the P6SMB62CH delivers tighter clamping (89.0 V), optimal VWM/VBR ratio for 48 V systems, and AEC-Q101 validation-making it preferred for automotive and high-reliability industrial deployments where precise voltage limiting and qualification traceability are mandatory.

FAQ
What is the polarity configuration of the P6SMB62CH?
The P6SMB62CH is a unidirectional TVS diode, with cathode marked by a band on the DO-214AA (SMB) package body. It conducts only when the cathode is positive relative to the anode, making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants like P6SMB62CAH, which protect both polarities.
Does the P6SMB62CH meet automotive qualification standards?
Yes, the P6SMB62CH is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD47. Its compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b further validates its suitability for automotive power network protection.
What is the maximum clamping voltage of the P6SMB62CH under surge conditions?
The P6SMB62CH has a maximum clamping voltage (VC) of 89.0 V at 7.0 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value is guaranteed across temperature and ensures protected circuits remain below critical voltage thresholds during standardized surge events.
How does the P6SMB62CH compare to the P6SMB62AH variant?
The P6SMB62CH has a VBR range of 55.8–68.2 V and VWM of 50.2 V, while the P6SMB62AH offers tighter VBR (58.9–65.1 V) and higher VWM (53.0 V). Both share identical package, power rating, and qualification-choose P6SMB62CH for broader tolerance applications and P6SMB62AH for tighter voltage margin control.
Is the P6SMB62CH compliant with lead-free and halogen-free requirements?
Yes, the P6SMB62CH is RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads meet J-STD-002 solderability standards, and the molding compound achieves UL 94V-0 flammability rating-ensuring environmental and safety compliance for global electronics manufacturing.
