Product details
Overview
P6SMB30H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with breakdown voltage 27.0–33.0 V, stand-off voltage 24.3 V, clamping voltage 43.5 V at 14.0 A peak pulse current, and AEC-Q101 qualification for automotive-grade surge protection in power rails and signal lines.
For engineers reviewing the P6SMB30H datasheet, P6SMB30H pinout, P6SMB30H application, or P6SMB30H equivalent, this page delivers verified electrical specs, thermal performance, clamping behavior under ISO 7637-2 pulses, and real-world ESD/inductive switching protection use cases - all specific to the P6SMB30H variant.
Technical Context
The P6SMB30H uses a glass-passivated silicon junction optimized for fast response (<1.0 ps rise time from 0 V to VBR(min)) and low leakage (<1 µA @ 24.3 V). It operates within -55°C to +150°C junction temperature range and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity requirements for automotive electronics.
Its unidirectional configuration provides reverse-biased clamping only, with forward voltage of 3.5 V @ 50 A (per family spec), junction-to-case thermal resistance of 10°C/W, and moisture sensitivity level 1 per J-STD-020 - enabling high-reliability automated SMT assembly without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 27.0 V / 33.0 V - defines guaranteed avalanche initiation window under 1.0 mA test current |
| VWM | 24.3 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 43.5 V @ 14.0 A - clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPSM | 600 W - non-repetitive peak pulse power handling capability per standard waveform |
| TJ(max) | +150°C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJC | 10°C/W - enables effective heat transfer to PCB copper when mounted with adequate thermal pad |
| Leakage @ VWM | <1 µA - ensures minimal standby power loss in always-on vehicle modules |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply inputs in telematics control units exposed to ISO 7637-2 Pulse 2b (load dump) and Pulse 5a (alternator surge). IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between input rail and chassis ground. Use Value: Limits transient voltage to ≤43.5 V, preventing damage to downstream DC-DC converters and microcontrollers rated for 36 V absolute max. | Use Scenario: Safeguarding analog front-end inputs of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Reverse-biased transient shunt on sensor signal lines subject to ESD and relay coil flyback. Use Value: Clamps 8 kV contact ESD events to <45 V within <1 ps, preserving ADC accuracy and avoiding latch-up in precision op-amps. |
| LED Lighting Driver Protection | Automotive CAN Bus Node Protection |
Use Scenario: Guarding constant-current LED driver ICs in commercial vehicle headlamp modules against inductive switching spikes from relay-controlled power stages. IC Role / Device Role / Timing Role: Standoff-rated TVS on driver VIN rail, activated only during >24.3 V surges. Use Value: Absorbs 600 W peak energy without degradation, maintaining luminous output stability across 10,000+ switching cycles. | Use Scenario: Secondary-level protection on CAN_H/CAN_L lines in gateway ECUs interfacing with multiple vehicle domains. IC Role / Device Role / Timing Role: Unidirectional clamping element referenced to ground, used alongside common-mode choke and primary TVS. Use Value: Suppresses asymmetrical fast transients (e.g., EFT burst) while adding <1 pF capacitance - no data rate impact on 500 kbps CAN FD links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Bidirectional variant; VBR = 33.3–36.8 V; VC = 48.4 V @ 12.4 A; same SMB package | Required where bidirectional clamping needed (e.g., AC-coupled data lines); not suitable for DC rail-only protection | Select P6SMB30H for unidirectional 24 V rail protection; choose SMBJ30A only if symmetrical surge threat exists. |
| 1.5SMC33A | Higher power rating (1500 W); larger DO-214AB (SMC) package; VC = 53.3 V @ 28.1 A | Used in higher-energy industrial surge environments (e.g., motor drives); incompatible footprint | P6SMB30H fits space-constrained automotive layouts; 1.5SMC33A requires PCB redesign but handles longer-duration transients. |
Compared with SMBJ30A and 1.5SMC33A, the P6SMB30H offers optimal balance of AEC-Q101 compliance, compact SMB footprint, and precise 24.3 V standoff for 24 V system protection - making it the preferred choice where automotive qualification and board area are critical.

FAQ
What is the breakdown voltage range of the P6SMB30H?
The P6SMB30H has a specified breakdown voltage range of 27.0 V to 33.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This window ensures reliable avalanche initiation across process variation and temperature, and directly supports its use as a 24 V system protector with 24.3 V stand-off rating.
Is the P6SMB30H suitable for automotive applications?
Yes, the P6SMB30H is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b requirements. Its DO-214AA package, MSL Level 1 rating, and -55°C to +150°C operating range make it suitable for engine bay, body control, and infotainment modules - confirmed by Taiwan Semiconductor's official qualification report for the P6SMBxH family.
What is the clamping voltage of the P6SMB30H under surge conditions?
The P6SMB30H clamps to a maximum of 43.5 V at 14.0 A peak pulse current (10/1000 µs waveform). This value is measured and guaranteed per datasheet specifications, ensuring downstream components see no more than 43.5 V during standardized surge events - critical for protecting 36 V-rated power management ICs.
Does the P6SMB30H have polarity markings, and how is it oriented on the PCB?
Yes, the P6SMB30H features a cathode band marking on the DO-214AA (SMB) package body. During PCB layout, the banded end must connect to the protected line (e.g., 24 V rail), while the anode connects to ground - establishing correct unidirectional clamping polarity per the device's internal junction structure.
How does the P6SMB30H compare to the P6SMB30AH variant?
The P6SMB30AH has tighter breakdown tolerance (28.5–31.5 V vs. 27.0–33.0 V), higher stand-off voltage (25.6 V vs. 24.3 V), and slightly lower clamping voltage (41.4 V vs. 43.5 V at 15.0 A). Both share identical package, AEC-Q101 qualification, and thermal specs - select P6SMB30H for cost-sensitive designs where wider VBR is acceptable, P6SMB30AH for tighter voltage margin control.
