Product details
Overview
P6SMB36H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage range of 32.4–39.6 V, clamping voltage of 52.0 V at 12.0 A peak pulse current, and stand-off voltage of 29.1 V. It features AEC-Q101 qualification, glass passivated junction, and DO-214AA (SMB) package for automotive and industrial surge protection.
For engineers reviewing the P6SMB36H datasheet, P6SMB36H pinout, P6SMB36H application, or P6SMB36H equivalent, key selection criteria include its 600W peak pulse power rating, 1.0 mA test current, <1 µA reverse leakage at VWM, 10/1000 µs waveform compliance, and ISO 7637-2 Pulse 1/2a/2b/3a/3b immunity support.
Technical Context
The P6SMB36H operates as a unidirectional avalanche diode optimized for fast transient suppression in DC power rails and signal lines. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at 29.1 V), while its thermal resistance (RθJA = 55 °C/W) supports operation up to +150 °C junction temperature.
Designed per ANSI/IEEE C62.35, it delivers sub-nanosecond response time (<1.0 ps from 0 V to VBR(min)) and meets automotive-grade reliability requirements including JESD201 Class 2 whisker resistance and moisture sensitivity level 1 (J-STD-020).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 32.4 V / 39.6 V - defines guaranteed avalanche conduction onset under 1.0 mA test current |
| VWM | 29.1 V - maximum continuous reverse operating voltage before significant leakage |
| VC @ IPPM | 52.0 V at 12.0 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPSM | 600 W - peak pulse power handling capability under standardized transient waveform |
| IR @ VWM | <1 µA - ultra-low reverse leakage preserves system standby power integrity |
| TJ(max) | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Package | DO-214AA (SMB) - surface-mount footprint compatible with automated assembly and IPC-7351B land patterns |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in vehicle ECUs against load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power input and ground to shunt transients exceeding 29.1 V. Use Value: Limits voltage seen by downstream regulators and microcontrollers to ≤52.0 V during 600 W surges, preventing latch-up or permanent damage. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) in factory automation PLC modules. IC Role / Device Role / Timing Role: Bidirectional-capable variant not used; this unidirectional P6SMB36H protects grounded-signal paths from positive-going ESD or coupling events. Use Value: Sub-ns response ensures clamping occurs before sensitive ADC front-ends are overstressed, preserving measurement accuracy and longevity. |
| LED Driver Output Protection | Telecom DC Power Input Protection |
Use Scenario: Shielding constant-current LED driver outputs from back-EMF during hot-plug or cable disconnect events. IC Role / Device Role / Timing Role: Connected anode-to-ground, cathode-to-output rail to clamp positive transients on the driver output node. Use Value: Withstands repetitive 10/1000 µs surges up to 600 W while maintaining <1 µA leakage-no impact on driver efficiency or dimming fidelity. | Use Scenario: Hardening -48 V telecom power inputs against lightning-induced surges and switching noise in remote radio units. IC Role / Device Role / Timing Role: Placed across input terminals to clamp common-mode transients relative to chassis ground. Use Value: 52.0 V clamping voltage ensures downstream DC/DC converters remain within absolute maximum ratings even during worst-case 600 W impulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Same DO-214AA package, bidirectional, VBR = 40–44.2 V, VC = 58.1 V @ 10.3 A | Supports AC-coupled or floating-rail protection where polarity reversal may occur | Select SMBJ36A only if bidirectional clamping is required; P6SMB36H offers tighter VBR tolerance and lower clamping for unidirectional 24 V systems. |
| 1.5SMC36A | DO-214AB (SMC) package, larger footprint, same VBR/VC specs, higher PPPSM = 1500 W | Used where higher surge margin or legacy board space allows larger SMC footprint | Choose 1.5SMC36A only when 1500 W rating is mandatory; P6SMB36H provides optimal 600 W density for space-constrained automotive modules. |
Compared with SMBJ36A and 1.5SMC36A, the P6SMB36H delivers superior board-area efficiency in unidirectional 24 V protection, tighter VBR distribution (±10%), and AEC-Q101 validation out-of-box-making it preferred for new automotive designs targeting ASIL-B functional safety zones.

FAQ
What is the breakdown voltage range of the P6SMB36H?
The P6SMB36H has a specified breakdown voltage (VBR) range of 32.4 V to 39.6 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range reflects manufacturing tolerance and ensures reliable conduction onset above the 29.1 V stand-off voltage while accommodating thermal drift across its -55 °C to +150 °C operating range. The P6SMB36H maintains this specification under JEDEC-standard test conditions.
Is the P6SMB36H suitable for automotive applications?
Yes, the P6SMB36H is AEC-Q101 qualified and explicitly designed for automotive use. It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transient immunity requirements and is rated for junction temperatures up to +150 °C. Its glass passivated junction, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 make the P6SMB36H appropriate for engine control units, body control modules, and ADAS power supplies.
What is the clamping voltage of the P6SMB36H under surge conditions?
The P6SMB36H clamps to a maximum of 52.0 V when subjected to its rated 12.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This clamping voltage is guaranteed across temperature and lifetime, ensuring downstream ICs see no more than 52.0 V during transient events. The P6SMB36H achieves this with minimal voltage overshoot due to its sub-nanosecond response time.
Does the P6SMB36H have bidirectional capability?
No, the P6SMB36H is a unidirectional TVS diode, intended for protection of polarized DC circuits. Its cathode band marks the high-side connection point. For bidirectional applications (e.g., AC lines or floating signals), TSC offers the P6SMB36AH variant or the SMBJ36A series. The P6SMB36H must be oriented with cathode toward the protected line and anode to ground to function correctly.
What packaging and reel quantity does the P6SMB36H ship in?
The P6SMB36H is supplied in DO-214AA (SMB) package format on 3,000-piece tape-and-reel carriers, compliant with EIA-481 standards. The reel includes matte tin-plated leads, RoHS-compliant and halogen-free molding compound (per IEC 61249-2-21), and laser-marked LUJ device code. This packaging supports high-speed pick-and-place assembly and satisfies IPC-A-610 Class 2/3 solderability requirements.
