Product details
Overview
P6SMB62H from Taiwan Semiconductor is a unidirectional 600W surface-mount Transient Voltage Suppressor (TVS) diode with a nominal breakdown voltage of 55.8–68.2 V, clamping voltage of 89.0 V at 7.0 A peak pulse current, and stand-off voltage of 50.2 V. It features glass-passivated junction, AEC-Q101 qualification, and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transient immunity.
For engineers reviewing the P6SMB62H datasheet, P6SMB62H pinout, P6SMB62H application, or P6SMB62H equivalent, this device is selected for high-reliability DC power rail protection in automotive ECUs, industrial control I/O modules, and LED driver input stages where fast clamping (<1.0 ps response), low leakage (<1 µA @ 50.2 V), and robust 600W surge handling are required.
Technical Context
The P6SMB62H operates as a unidirectional avalanche diode, conducting only in reverse bias above its breakdown threshold to shunt transients away from downstream circuitry. Its DO-214AA (SMB) package enables automated placement and supports 100 A non-repetitive forward surge current (IFSM) and 150 °C maximum junction temperature.
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, enabling effective heat dissipation in compact PCB layouts. Electrical behavior follows ANSI/IEEE C62.35 standards, with VBR tested at 1.0 mA and clamping verified per 10/1000 µs waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Automotive Power Rail Protection | Industrial I/O Module Protection |
|---|---|
|
Use Scenario: Protecting 12 V supply lines in engine control units against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and LDO/regulator input to clamp surges before regulation stage. Use Value: Limits peak voltage to ≤89.0 V during 600 W transients, preventing regulator latch-up or MOSFET gate oxide failure. |
Use Scenario: Safeguarding analog input channels of PLC digital I/O cards from field-wiring induced EFT bursts. IC Role / Device Role / Timing Role: Front-end transient suppressor on signal conditioning path, upstream of op-amp and ADC. Use Value: Sub-µA leakage at 50.2 V avoids loading precision reference voltages; 89.0 V clamping protects 16-bit ADC front-end. |
| LED Driver Input Stage | DC Motor Control Board |
|
Use Scenario: Shielding constant-current LED driver ICs from inductive kickback during PWM dimming or hot-swap events. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor input to absorb back-EMF spikes from switching FETs.

Use Scenario: Suppressing commutation spikes generated by brushed DC motors in robotics and actuator control boards. IC Role / Device Role / Timing Role: Mounted directly across motor terminals to clamp flyback voltage before H-bridge MOSFETs. Use Value: 150 °C junction rating allows sustained operation near motor housings; DO-214AA footprint fits tight mechanical envelopes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Bidirectional variant; VBR = 71.1–78.6 V; VC = 103 V @ 5.8 A; same DO-214AA package | Required where bidirectional surge protection (e.g., AC-coupled data lines) is needed instead of unidirectional DC rail clamping | Select SMBJ64A only if bipolar transient immunity is mandated; P6SMB62H offers tighter VBR tolerance and lower clamping for 12 V–24 V DC systems |
| 1.5SMC62A | Higher power rating (1500 W); larger DO-214AB (SMC) package; VC = 101 V @ 14.9 A; VWM = 53.0 V | Suitable for higher-energy transients (e.g., 24 V truck systems with >1 kV load dump) where PCB area permits larger footprint | Choose 1.5SMC62A when surge energy exceeds 600 W capability; P6SMB62H remains optimal for space-constrained 600 W designs with SMB footprint constraints |
Compared with SMBJ64A and 1.5SMC62A, the P6SMB62H delivers optimized clamping performance (89.0 V) and tighter VBR range (55.8–68.2 V) in the smallest standardized SMB package, making it preferred for cost-sensitive, high-volume automotive and industrial DC protection where 600 W surge handling suffices.

FAQ
What is the breakdown voltage range for P6SMB62H?
The P6SMB62H has a guaranteed breakdown voltage range of 55.8 V to 68.2 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range reflects process tolerance and ensures consistent clamping behavior across production lots while maintaining compatibility with 60 V system margins. The P6SMB62H datasheet specifies these values under TA = 25°C conditions.
Is P6SMB62H suitable for automotive applications?
Yes, the P6SMB62H is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transient immunity standards-making it suitable for under-hood and chassis-mounted automotive electronics. Its 150 °C maximum junction temperature, glass-passivated junction, and moisture sensitivity level 1 rating further validate its use in harsh automotive environments. The P6SMB62H is commonly deployed in engine control units and body control modules.
What is the clamping voltage of P6SMB62H at peak pulse current?
The P6SMB62H clamps to a maximum of 89.0 V at 7.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during surge events. The low clamping ratio (VC/VBR(min) ≈ 1.59) confirms efficient transient suppression for the P6SMB62H.
Does P6SMB62H have polarity marking, and how is it identified?
Yes, the P6SMB62H uses a cathode band marking on the DO-214AA (SMB) package to indicate polarity. The banded end is the cathode and must be connected toward the higher-potential side of the protected line (e.g., +12 V rail), while the unmarked end is the anode. This unidirectional configuration ensures proper avalanche conduction during reverse-biased transients. The P6SMB62H marking code is "MLJ" per the manufacturer's ordering table.
What packaging and reel quantity is offered for P6SMB62H?
The P6SMB62H is supplied in DO-214AA (SMB) package format on tape-and-reel, with 3,000 units per reel. This packaging supports automated SMT assembly and complies with J-STD-020 moisture sensitivity level 1 requirements, eliminating bake-out prior to reflow. The P6SMB62H reel format is standard across authorized distributors and aligns with IPC-7351B land pattern recommendations.
